OIF’s Optical Masterclass Series at NGON to Include Updates on 400ZR, Common Electrical I/O, Flex Ethernet & SDN Projects

Fremont, Calif.—May 8, 2019 – At NGON, May 21-23, 2019, OIF experts will kick off the Optical Masterclass Series with a comprehensive update on its 400ZR, Common Electrical I/O (CEI)-112, Flex Ethernet (FlexE) and Software Defined Networking (SDN) projects.

“OIF’s interoperability solutions are vital to the global network and with many of the key network operators in attendance, NGON is the ideal platform to provide updates on OIF’s work in 400ZR, CEI, FlexE and SDN,” said Dave Brown, Nokia and OIF Director of Communications.

The “Optical Masterclass Series – The Optical Internetworking Forum” session is being held Tuesday, May 21, 2019 from 09:00 – 11:00 (NEW TIME AS OF 5/16). Brown and Karl Gass, OIF Physical & Link Layer Working Group Vice Chair, Optical, will discuss how OIF is assuring interoperability in open, agile, next-generation optical networks and provide updates on crucial industry projects.

400ZR

OIF’s 400ZR project is critical in facilitating the reduction of cost and complexity for high bandwidth data center interconnects and promoting interoperability among optical module manufacturers. This Implementation Agreement (IA) will specify an interoperable digital coherent 400ZR interface targeted at short reach (80 km or more) DWDM amplified noise limited links and unamplified loss limited links.

CEI

The CEI project update will include discussion of the multiple 112 Gb/s interfaces being defined by OIF including CEI-112G MCM, XSR, VSR, MR and LR. Applications of these 112 Gb/s interfaces include die-to-die, die-to-OE (optical engine) on package, chip-to-module, chip-to-chip and chip-to-chip long reach over backplane and cables.

FlexE

OIF continues to lead in FlexE aggregation architectures through its newest FlexE 2.1 project for FlexE over 50GbE PHY applications, an extension to its FlexE 2.0 Implementation Agreement (IA). FlexE 2.1 will specify a 50G FlexE frame and multiplexing format and will address FlexE applications with lower bandwidth needs and provide an implementation foundation for applications including the access layer of the future 5G mobile network.

SDN

In November 2018, OIF announced the launch of “Requirements for Integrated Packet Optical SDN.” The project outlines requirements for a multi-layer SDN reference architecture as a use case for packet optical transport networks. It will generate functional requirements, a reference architecture and use cases for packet/optical networks guided by the vision to enable agile, open network solutions that simplify operations and optimize resource utilization.

IC-TROSA

The session will also include an update on the Integrated Coherent Transmit-Receive Optical Sub Assembly (IC-TROSA) project that defines a standard optical component containing a complete coherent modem. The availability of highly integrated components accelerates the adoption of coherent transmission into additional markets.

Additionally, Gass will participate in Wednesday’s Plenary session, 09:30 – 10:10, “Present View: To the terabit & beyond – practicalities for coherent transmission.” Also on Wednesday, from 14:35 – 15:30, Brown will speak on the “Open Source Approach: Looking at disaggregation as a pathway for multi-vendor cooperation, interoperability and driving enhanced network interfaces” panel.

T-API taps into the transport layer

This article originally appeared on Gazettabyte by editor Roy Rubenstein: http://www.gazettabyte.com/home/2018/8/20/t-api-taps-into-the-transport-layer.html

The Optical Internetworking Forum (OIF) in collaboration with the Open Networking Foundation (ONF) and the Metro Ethernet Forum (MEF) have tested the second-generation transport application programming interface (T-API 2.0).

SK Telecom’s Park Jin-hyo

T-API 2.0 is a standardised interface, released in late 2017 by the ONF, that enables the dynamic allocation of transport resources using software-defined networking (SDN) technology.

The interface has been created so that when a service provider, or one of its customers, requests a service, the required resources including the underlying transport are configured promptly.

The OIF-led interoperability demonstration tested T-API 2.0 in dynamic use cases involving equipment from several systems vendors. Four service providers – CenturyLink, Telefonica, China Telecom and SK Telecom – provided their networking labs, located in three continents, for the testing.

Packets and transport 

SDN technology is generally associated with the packet layer but there is also a need for transport links, from fibre and wavelength-division multiplexing technology at Layer 0 through to Layer 2 Ethernet.

Transport SDN differs from packet-based SDN in several ways. Transport SDN sets up dedicated pipes whereas a path is only established when packets flow for packet SDN. “When you order a 100-gigabit connection in the transport network, you get 100 gigabits,” says Jonathan Sadler, the OIF’s vice president and Networking Interoperability Working Group chair. “You are not sharing it with anyone else.”

Another difference is that at the packet layer with its manipulation of packet headers is a digital domain whereas the photonic layer is analogue. “A lot of the details of how a signal interacts with a fibre, with the wavelength-selective switches, and with the different componentry that is used at Layer 0, are important in order to characterise whether the signal makes it through the network,” says Sadler.

T-API 1.0 is a configure and step-away deployment, T-API 2.0 is where the dynamic reactions to things happening in the network become possible

Prior to SDN, control functions resided on a platform as part of a network’s distributed control plane. Each vendor had their own interface between the control and the optical domain embedded within their platforms. T-API has been created to expose and standardise that interface such that applications can request transport resources independent of the underlying vendor equipment.

NBI refers to a northbound interface while SBI stands for a southbound interface. Source: OIF.

To fulfil a connection across an operator’s network involves a hierarchy of SDN controllers. An application’s request is first handled by a multi-domain SDN controller that decomposes the request for the various domain controllers associated with the vendor-specific platforms. T-API 2.0’s role is to link the multi-domain controller to the application layer’s orchestrator and also connect the individual domain controllers to the multi-domain SDN controller (see diagram above). T-API is an example of a northbound interface.

The same T-API 2.0 interface is used at both SDN controller levels, what differs is the information each handles. Sadler compares the upper T-API 2.0 interface to a high-level map whereas the individual TAPI 2.0 domain interfaces can be seen as maps with detailed ‘local’ data.  “Both [interfaces] work on topology information and both direct the setting-up of connections,” says Sadler. “But the way they are doing it is with different abstractions of the information.”

T-API 2.0

The ONF developed the first T-API interface as part of its Common Information Model (CIM) work. The interface was tested in 2016 as part of a previous interoperability demonstration involving the OIF and the ONF.

One important shortfall revealed during the 2016 demonstrations, and which has slowed its deployment, is that the T-API 1.0 interface didn’t fully define how to notify an upper controller of events in the lower domains. For example, if a link is congested, or worst, lost, it couldn’t inform the upper controller to re-route traffic. This has been put right with T-API 2.0.

“T-API 1.0 is a configure and step-away deployment, T-API 2.0 is where the dynamic reactions to things happening in the network become possible,” says Sadler.

When it comes to the orchestrator tying into the transport network, we do believe T-API will be one of the main approaches for these APIs

Interoperability demonstration

In addition to the four service providers, six systems vendors took part in the recent interoperability demonstration: ADVA Optical Networking, Coriant, Infinera, NEC/ Netcracker, Nokia and SM Optics.

The recent tests focussed on the performance of the TAPI-2.0 interface under dynamic network conditions. Another change since the 2016 tests was the involvement of the MEF. The MEF has adopted and extended T-API as part of its Network Resource Modeling (NRM) and Network Resource Provisioning (NRP) projects, elements of the MEF’s Lifecycle Service Orchestration (LSO) architecture. The LSO allows for service provisioning using T-API extensions that support the MEF’s Carrier Ethernet services.

Three aspects of the T-API 2.0 interface were tested as part of the use cases: connectivity, topology and notification.

Setting up a service requires both connectivity and topology. Topology refers to how a service is represented in terms of the node edge points and the links. Notification refers to the northbound aspect of the interface, pushing information upwards to the orchestrator at the application layer. This allows the orchestrator in a multi-domain network to re-route connectivity services across domains.

The four use cases tested included multi-layer network connections whereby topology information is retrieved from a multi-domain network with services provisioned across domains.

T-API 2.0 was also used to show the successful re-routing of traffic when network situations change such as a fault, congestion, or to accommodate maintenance work. Re-routing can be performed across the same layer such as the IP, Ethernet or optical layer, or, more optimally, across two or more layers. Such a capability promises operators the ability to automate re-routing using SDN technology.

The two other use cases tested during the recent demonstration were the orchestrator performing network restoration across two or more domains, and the linking of data centres’ network functions virtualisation infrastructure (NFVI).  Such NFVI interconnect is a complex use case involving SDN controllers using T-API to create a set of wide area networks connecting the NFV sites. The use case set up is shown in the diagram below.

Source: OIF

SK Telecom, one of the operators that participated in the interoperability demonstration, welcomes the advent of T-API 2.0 and says how such APIs will allow operators to enable services more promptly.

“It has been difficult to provide services such as bandwidth-on-demand and networking services for enterprise customers enabled using a portal,” says Park Jin-hyo, executive vice president of the ICT R&D Centre at SK Telecom. “These services will be provided within minutes, according to the needs, using the graphical user interface of SK Telecom’s network-as-service platform.”

SK Telecom stresses the importance of open APIs in general as part of its network transformation plans. As well as implementing a 5G Standalone (SA) Core, SK Telecom aims to provide NFV and SDN-based services across its network infrastructure including optical transport, IP, data centres, wired access as well as networks for enterprise customers.

“Our final goal is to open the network itself to enterprise customers via an open API,” says Park. “Our mission is to create 5G-enabled network-slicing-based business models and services for vertical markets.”

Takeways

The OIF says the use cases have shown that T-API 2.0 enables real-time orchestration and that the main shortcomings identified with the first T-API interface have been addressed with T-API 2.0.

The OIF recognises that while T-API may not be the sole approach available for the industry – the IETF has a separate activity – the successful tests and the broad involvement of organisations such as the ONF and MEF make a strong case for T-API 2.0 as the approach for operators as they seek to automate their networks.

“When it comes to the orchestrator tying into the transport network, we do believe T-API will be one of the main approaches for these APIs,“ says Sadler.

SK Telecom said participating in the interop demonstrations enabled it to test and verify, at a global level, APIs that the operators and equipment manufacturers have been working on. And from a business perspective, the demonstration work confirmed to SK Telecom the potential of the ‘global network-as-a-service’ concept.

OIF CONCLUDES SUCCESSFUL SDN TRANSPORT API INTEROPERABILITY TESTING – RESULTS TO BE REVEALED TODAY AT NGON

Multi-vendor demo showcases new dynamic behavior uses cases and deployment scenarios

Nice, France—June 26, 2018 – Following a six week testing period, the OIF (Optical Internetworking Forum) today announced the conclusion of its 2018 Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) multi-vendor interoperability demonstration. The much-anticipated demo results will be revealed during a public read-out event being held today from 10:00am-12:00pm at NGON & DCI Europe 2018 in Nice, France. ClicktoTweet

Additionally, Juan Pedro Fernández Palacios, Head of Unit, Telefónica will discuss Telefonica’s view of the demo results and use cases during his NGON keynote presentation tomorrow, June 27th.

“In bringing together service providers and optical networking vendors to demonstrate new SDN deployment scenarios including dynamic-behavior use cases, the OIF in collaboration with MEF has taken another important step towards providing the foundation for service providers to efficiently deliver dynamic multi-domain connectivity services to market,” stated Heidi Adams, Senior Research Director, IP & Optical Networks, IHS Markit. “With the 2018 demo event, the T-API 2.0 interface from the Open Networking Foundation (ONF) is on its way to becoming a standard northbound interface (NBI) to SDN transport network controllers.”

OIF, in collaboration with MEF, is leading the industry toward the validation and widespread commercialization of T-API 2.0 from the Open Networking Foundation (ONF) as a standard northbound interface (NBI) to transport network controllers.

The multi-vendor demo led by four network operator labs included lab deployed and cloud deployed systems testing new dynamic behavior use cases and deployment scenarios. The demo also incorporated service provisioning scenarios at the LSO Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile Specification (MEF 60), which defines extensions to T-API in support of Carrier Ethernet services.

“The OIF SDN Interoperability demonstration has successfully brought together carriers, vendors and integrators with a common goal of moving to an open API (TAPI),” said Jack Pugaczewski, Distinguished Architect, CenturyLink. “T-API is a key enabler for providing automated service fulfillment and assurance. We have tested the Connectivity, Topology and Notification software patterns that T-API provides. Common APIs reduce design, development and deployment cycles for all involved, thus getting to market faster and realizing the financial benefits of automation.”

Participating network operators were CenturyLink, China Telecom, SK Telecom and Telefónica and vendors included ADVA, Coriant, Infinera, NEC/Netcracker, Nokia and SM Optics. Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) was a participating academic institution and TELUS Communications participated as a consulting network operator.

Additionally, two private events detailing the test results will be held with participating network operators: CenturyLink on July 10 in Denver, Colorado and China Telecom on July 19 in Beijing. Members of the media and analyst community interested in attending, please contact leah@wilkinson.associates.

“The OIF’s goal for interop events is to improve the quality and clarity of specifications being tested,” explained Jonathan Sadler, OIF VP and Networking & Operations Interoperability Working Group Chair. “As the tests were performed, we noted possible points for misunderstanding and places where the specifications may be enhanced. These results will be liaised to ONF and MEF for review at future meetings.”

A technical white paper and an executive summary of the demo result will be available in August.

OIF CONFIRMS PARTICIPANTS FOR 2018 JOINT-NETWORK OPERATOR, MULTI-VENDOR SDN TRANSPORT API INTEROPERABILITY DEMONSTRATION

April 10, 2018  Liz Smeds

Focused on accelerating the commercialization of transport SDN, leading global network operators and vendors will test new, more dynamic use cases

Fremont, Calif. —April 10, 2018 – Committed to accelerating the commercialization of transport SDN worldwide, the Optical Internetworking Forum (OIF) today announced plans for its 2018 Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) interoperability demonstration. In collaboration with MEF, this year’s demonstration will bring new dynamic behavior use cases and deployment scenarios into network operator labs around the world to test and validate the industry leading T-API 2.0 northbound interface (NBI) from the Open Networking Foundation (ONF).

The 2018 event builds on the OIF’s previous 2016 interoperability test and demonstration which addressed multi-layer and multi-domain environments as well as on the 2014 demo which prototyped the use of Northbound APIs and helped advance transport SDN standardization. The event will also incorporate service provisioning scenarios at the LSO (Lifecycle Service Orchestration) Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile Specification (MEF 60), which defines T-API extensions in support of MEF Carrier Ethernet services.

Network operators are rapidly moving toward giving customers and their applications the ability to dynamically control services, and do it in real-time. The days of waiting for service changes will soon be a thing of the past. To achieve this, they need the ability to dynamically move capacity quickly in open networks to avoid network congestion and provide better services to customers.

“With network operators leading the charge for more dynamic and open networks, there has to be widespread adoption of transport SDN. Through working through the specifications, rigorous interoperability testing and validation, this year’s demo is intended to substantiate T-API as the NBI of choice,” said Dave Brown, Nokia and OIF President. “We also look forward to our collaboration with MEF and the depth of expertise the organization brings to this demonstration.”

“MEF is pleased to contribute our LSO Presto NRP API work in support of the OIF SDN Transport API Interop Demo as we advance toward a common goal of orchestrating dynamic services over automated networks powered by SDN and LSO,” said Pascal Menezes, CTO, MEF. “This is exactly the type of collaboration that we need to accelerate industry innovation and deliver lasting value for service providers and their end customers.”

“The work done by OIF is critically important to network operators around the world as we work to provide our customers with better services and higher efficiency, which will definitely help the monetization of our network capacity,” said Dr. Junjie Li, China Telecom and OIF Network Operator Working Group Chair.

The international joint-network operator, multi-vendor optical networking interoperability demonstration includes network operator hosts CenturyLink, China Telecom, SK Telecom and Telefonica and participating vendors include ADVA Optical Networking SE, Coriant, NEC/Netcracker, Nokia, SM Optics and ZTE Corporation.

OIF Updates Micro Intradyne Coherent Receiver IA for Beyond 100G Applications

Forum soliciting input for next global interop demo

Optical Internetworking Forum (OIF) members recently approved important updates to the Micro Intradyne Coherent Receiver implementation agreement. The IA introduces three classes of receivers, distinguished by their RF frequency response, to support Flex Coherent DWDM transmission to 400G and beyond.

The OIF continues its efforts to look beyond 100G by selecting a 400G implementation technology option. The newly published Flex Coherent DWDM Transmission framework document specifies a single technical approach for diverse network applications, including long-haul (LH), metro and data center inter-connection (DCI).  One of the objectives of this work is to provide direction on the technical developments required by system and component providers.

“Our system vendor members continue to flow down future system requirements so that component suppliers can be ready with products to support their designs,” said Karl Gass of Qorvo and the OIF’s Physical and Link Layer Working Group – Optical Vice Chair.

OIF Approves Virtual Transport Network Service Implementation Agreement

Tad Hofmeister of Google joins board of directors

Members of the Optical Internetworking Forum (OIF) recently met in Ljubljana, Slovenia for a quarterly technical committee and approved an implementation agreement (IA) for an optical Virtual Transport Network Service.  They also made progress on the 400G-ZR project and were given a presentation on 100G and Beyond by Andre Pucko of Telekom Slovenije d.d.  Additionally, Tad Hofmeister of Google joins the board of directors, filling an open seat.

A Virtual Transport Network Service (VTNS) is the creation and offering of a Virtual Network (VN) by a provider to a user and is built on the virtualization of transport network resources. VNs may be dynamically created, deleted, or modified and users can perform connection management, connection monitoring and connection protection within their VN.

“Development of Transport SDN (Software Defined Networking) will enable service providers to offer new revenue generating services,”  said Lyndon Ong of Ciena and the OIF’s Market Awareness & Education Committee Co-Chair, Networking. “VTNS is one class of services of interest to many operators and can become a main driver for the deployment of SDN in their transport networks.”

In specifying the new VTNS IA, OIF identifies the requirements and characteristics of different virtual network service types, such as dynamic and static behaviors, as well as the attributes and parameters required for these service types and the requirements for support of service recovery and OAM. Different types of VTNS could be associated with operators offering, for example, Bandwidth on Demand (BoD) services, Network as a Service (NaaS) or Network Slicing for 5G Networking.

400G-ZR Project Update

The OIF’s 400G-ZR Interoperability project addresses both 400G ZR and short-reach DWDM multivendor interoperability such as might be required for cloud scale data center interconnect (DCI). The project made progress at the Q2 meeting by receiving 10 technical contributions addressing considerations such as power consumption of DSP, FEC proposals and experimental demos.  The work will continue to move forward with scheduled conference calls before the Q3 meeting.

OIF Concludes SDN Transport API Interoperability Testing

The Optical Internetworking Forum (OIF) conducted a six-week long global testing of the Transport Application Programming Interface (T-API) standard from the Open Networking Foundation (ONF). The OIF managed the multi-location demonstration which started in mid-October 2016 and concluded in December 2016.  Vendor participants executed a multi-domain path selection and recovery test plan with intra-lab and inter-lab testing across five carrier labs located in Asia, Europe and North America. A technical white paper on the demonstration is available to download here.

“As operators move from SDN PoCs and lab trials into commercial deployments, lack of interoperability between the SDN controllers and the orchestration layer above has quickly become the biggest technical barrier for many operators,” said Sterling Perrin, principal analyst, Heavy Reading. “Building a standardized northbound interface and successfully testing interoperability across different vendors and different networks – as the OIF has demonstrated – is a major step forward in addressing the northbound interface challenge and bringing SDN architectures to wide-scale commercial use.”

OIF SDN Transport API Interoperability Demonstration

The Optical Internetworking Forum (OIF) and the Open Networking Foundation (ONF) are leading the industry toward the wide scale deployment of commercial SDN by testing key Transport Application Programming Interfaces (T-API). The interoperability test and demonstration, managed by the OIF, addresses multi-layer and multi-domain environments in the following carrier labs; China Telecom, China Unicom, SK Telecom, Telefonica and Verizon. These carriers defined real world use cases including multi-domain orchestration of services delivered through Ethernet, OTN and optical switching. Carriers and vendors demonstrated how Network Function Virtualization (NFV) and SDN configured connectivity are combined to deliver service life cycle management.

Participating vendors include ADVA Optical Networking, Ciena, Coriant, Huawei Technologies Co., Ltd., Infinera, Juniper Networks, NEC Corporation, Sedona Systems, and SM Optics. Consulting carriers include Orange and TELUS.  Academic and/or research institution participants include China Academy of Telecommunication Research (CATR) and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).

Additional information can be found here.

Participants in the OIF Transport SDN interoperability event also submitted a proof of concept demo proposal to ETSI NFV.  The proposal, “Mapping ETSI-NFV onto Multi-Vendor, Multi-Domain Transport SDN”, was accepted and details are located here. The open demonstration of NFV concepts in a Proof of Concept (PoC) helps to build industrial awareness and confidence in NFV as a viable technology. Proofs of Concept also help to develop a diverse, open, NFV ecosystem. Results from PoCs may guide the work in the NFV ISG by providing feedback on interoperability and other technical challenges.

“Being able to dynamically establish connectivity between Virtual Network Functions enables carriers to provide greater service agility and reduce opex,” said Jonathan Sadler, of Coriant and the OIF Interoperability chair.  “Integrating multiple technologies using transport SDN further enables the right connectivity mechanisms used for service delivery.  Having this demonstration recognized by ETSI NFV provides building blocks for the development of future SDN-WAN.”

OIF Partners With UNH-IOL to Certify Optical Control Plane UNI

Enables Multi-vendor, Multi-layer Interoperability Using RSVP-TE Signaling

The Optical Internetworking Forum (OIF) today announced an agreement with the University of New Hampshire InterOperability Lab (UNH-IOL), an independent provider of testing and standards conformance services for the networking industry, to provide certification for Optical Control Plane User Network Interfaces (UNI) based on industry standards.  In line with OIF’s mission to enable global interoperability in optical transport networks, the Forum’s certification program will address the interoperability of optical and packet products, complementing OIF’s work on unlocking the benefits of SDN for carriers.

While an optical control plane is already deployed by a large number of operators around the world, interoperability between vendors is constrained by lack of an interoperable UNI. Multi-vendor interoperability of the optical control plane remains absent from commercial products, although various demonstrations have proven it is feasible.  The optical control plane facilitates operations and enables dynamic provisioning, restoration and optimization across optical networks. The UNI extends these capabilities to client nodes and the OIF’s UNI certification will help enable the availability of control plane interoperability in commercial products.

“The advent of interoperability in optical networks is a paradigm shift, which will dramatically increase flexibility and innovation in our networks,” said Philippe Lucas, SVP Strategy Architecture and Standards of Orange. “The OIF certification is a step to unlock the market by providing a unique reference and a critical market advantage to compliant, interoperable products.”

“The benefits of multi-vendor interoperability combined with certification can help broaden and accelerate the market for optical products, reduce costs, introduce new features and operational agility,” said Timothy Winters, Senior Executive of UNH-IOL.  “Certification can fulfill operator’s and vendor’s requirements with reduced repetitive testing and a higher level of confidence when going to market.”

“Development of the UNI certification test specification is happening at an important time in our industry,” said Tim Doiron, Principal Analyst Intelligent Networking, ACG Research.  “We’ve never gotten the optical domain out of vendor isolation when it comes to the optical control plane. Certification and interoperability will aid service providers in their migration toward a multi-vendor programmable, dynamic optical underlay with increasing automation, service agility and reduced operational costs.”

The Optical Control Plane UNI Certification Program

The new certification program, along with OIF’s well established and successful interop testing process and implementation agreements, helps the industry realize open, programmable and interoperable optical networks in commercial deployments, bringing to reality the promised benefits of transport SDN, with accelerated time-to-revenue coupled with increased operational efficiency. 

  • Certification is based on compliance with relevant industry standards including IETF RFCs on RSVP-TE signaling.
  • Addresses the main use cases enabled by an optical control plane, including simplified provisioning, automated path selection, dynamic restoration and multi-layer optimization.
  • Enables several deployment cases which are of primary importance to operators and require immediate interoperability, including IP/WDM integration, packet-optical interconnect, multilayer optimization and alien wavelength deployments.
  • Contributes to OIF efforts to unlock the benefits of SDN for flexible networks
  • Facilitates multi-vendor deployments.

Development of the UNI certification test specification is starting now. Visit the OIF webpage for more information. Formal testing of participating vendor products will start early 2017 and pre-testing is already open at UNH-IOL. The first OIF certified products are expected to be on the market in approximately 12 months from now.

To drive adoption of SDN, OIF demonstrates Transport Application Programming Interface (TAPI)

Ovum view

The goal of networking standards groups is to establish multivendor/multicarrier standards that interoperate. To achieve that goal, the OIF (Optical Internetworking Forum) is conducting a global interoperability demo to test software-defined networking (SDN) Transport Application Programming Interfaces (TAPI) among 5 global carriers and 11 system and software vendors. The tests cover services across optical, IP, and virtual appliance layers to see how services interact across the different vendors. In 1Q17, all issues identified will be presented to users and standard organizations to improve the performance and adoption of SDN. In doing this work, the OIF is performing a necessary step to drive adoption of multilayer and multivendor SDN.

OIF’s demonstration will lead to faster adoption of multilayer SDN

The OIF has been working to accelerate the deployment of new optical technology since its founding in 1998. In its 2014 demonstration of SDN transport architecture, the OIF established the need for common APIs for end-to-end orchestration for a multidomain network. Now, it is testing the Open Networking Foundation’s (ONF’s) SDN TAPI across 11 system participants: Adva, Ciena, Coriant, FiberHome, Huawei Technologies, Infinera, Juniper Networks, NEC Corporation, Sedona, SM Optics, and ZTE, with the support of five carriers – China Telecom, China Unicom, SK Telecom, Telefonica, and Verizon. The goal is to identify gaps in the current standards and work with standard bodies to address those gaps.

The demonstrations will abstract the topology for each carrier, including a virtual network in another carrier, setup of dynamic VNFs (virtual network functions), dynamic-connect IP services, and restore/setup of intra-lab optical connections. Each of these demonstrations will help vendors, carriers, and standard bodies see how complete the solutions are, and what needs to be done to progress multilayer interoperability between vendors and carriers.

Overall, the OIF is helping to move SDN and NFV (network functions virtualization) forward with the test of SDN TAPI. Vendors will benefit from knowing what applications need more work, and carriers will benefit from knowing how adoption of SDN/NFV can work across vendors and carriers so they can speed investment.

OIF Announces Plans for SDN Transport API Interoperability Demonstration

The Optical Internetworking Forum (OIF) announced today plans for a global Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) interoperability demonstration in the fall of 2016. The OIF is partnering with the Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating the adoption of open SDN, to take the testing into carrier labs worldwide and lead the industry towards the wide-scale deployment of commercial SDN. Network virtualization and flexibility to deal with peak traffic events, link failures and network slicing are driving motivations behind the demonstration. Currently the transport layer operates with no awareness of the packet layer above it, so manual intervention is often needed to address issues. By incorporating the T-API, the problems can be corrected automatically through software.

Host carriers for the demonstration include China Telecom, China Unicom, SK Telecom, Telefónica and Verizon. Participating vendors include ADVA Optical Networking, Ciena, Coriant, Fiberhome, Huawei Technologies Co., Ltd., Juniper Networks, NEC Corporation, Sedona Systems, SM Optics and ZTE. Consulting carriers include Orange and TELUS.  Academic and/or research institution participants include China Academy of Telecommunication Research (CATR) and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).

“In the modern operating environment, carriers need to dynamically move capacity to handle quickly changing traffic demands,” said Jonathan Sadler of Coriant and the OIF’s technical committee vice chair and acting networking interoperability chair. “The APIs that are being tested create a new breed of applications. Like so many of the interoperability agreements developed by the OIF, demand from carriers continues to drive the technical direction of the Forum.”

“ONF and the OIF are united in our goal of moving these technical advances into the market for the benefit of network operators and their users,” said Dan Pitt, executive director of the Open Networking Foundation. “We are pleased to extend our longstanding collaboration with the OIF on T-API, leveraging OIF’s specialized optical expertise, and these demonstrations inspire operators and vendors alike to accelerate development and deployment.”

One main focus of the global demonstration is the notification interface – the means for notifying applications that congestion is being observed, triggering moving around of traffic and addition of capacity. Additional use cases based upon the API standards will be clarified during the testing and defined through OIF implementation agreements to provide a common set of requirements. Regional demonstration read-out events will take place in early 2017 and a whitepaper describing the event will be available to the public.

OIF Publishes Transport SDN Framework Document

Key Findings from 2014 Demo Inspires Framework Architecture

Fremont, Calif. – May 19, 2015 –Following a 2014 prototype demonstration event, the Optical Internetworking Forum (OIF) has approved an SDN Framework whitepaper that paves the way for implementation of SDN in Carrier Networks. The whitepaper, titled “Framework for Transport SDN:  Components and APIs”, documents the SDN framework for multi-domain carrier networks.  It identifies critical open APIs for Transport SDN based on synthesis of the SDN layered architecture and the ITU-T ASON functional element model for optical network control.

SDN identifies interfaces separating infrastructure and control layers, and control layer from application layer.  The interface between infrastructure and control layers is termed the SouthBound Interface or SBI, the interface between control and application layers is termed the NorthBound Interface or NBI, and provides APIs to the application.

“In 2014, the prototype demonstration brought together multiple vendors and carriers to test cloud-bursting services, utilizing SDN principles and interfaces,” said Lyndon Ong of Ciena and co-chair of the OIF Market Awareness & Education Committee.  “The demonstration results factored into the development of a framework that allows SDN to be deployed over a carrier’s network with multiple, diverse domains.”

One of the key findings from the demonstration was that the separation introduced by the NBI and SBI enables SDN to be applied over greenfield (i.e., OpenFlow) and brownfield environments, allowing integration of domains controlled by management systems and domains using existing distributed control planes as well as centralized SDN.  A variety of SBI protocols could coexist in the carrier’s Transport SDN network, including the OpenFlow protocol, with extensions for optical networks.

NBI is an area of particular importance; by providing access to ASON functional elements, the NBI opens up access to the network control plane and provides greater programmability of services, improving the speed of service deployment and overall manageability of the network.  Functional elements accessible via NBI in this framework include Call Control, Connection Control, Topology and Path Computation.

The document assesses where existing protocols may be used to support NBI access.  In addition to existing protocols, there are benefits from defining new REST-based interfaces such as were prototyped in the demo, based on a common information model.

OIF Launches New Project to Identify APIs for Transport SDN

Close on the heels of the joint Optical Internetworking Forum (OIF) and Open Networking Foundation (ONF) Global Transport SDN demonstration that concluded in October, the OIF has launched a new project to develop implementation agreements (IAs) for the application programming interfaces (APIs) used between application and network controller during the event. The new initiative will build on the Service Request and Topology APIs prototyped in the demonstration, culminating in IAs for use by carriers and equipment vendors. The new initiative will also create IAs for Service Request, Path Computation, Topology and Link Resource Manager interfaces that have been identified as part of the OIF’s upcoming SDN Framework document. The APIs to be delivered by the new project are based on REST and JSON principles enabling rapid and flexible application development.

“The prototype Transport SDN demonstration revealed a lack of definition for how user applications interact with transport network applications and resource functions,” said Jonathan Sadler, of Coriant and the OIF technical committee vice chair. “The programmability of Transport SDN requires some of the internal interfaces used by ASON to become open.”

In particular, a Service API is important as it allows applications to request connectivity services from the network. Having a common Service API allows a variety of applications to access services provided by the network, particularly in an environment with multiple domains with potentially different underlying control methods.

During the Global Transport SDN demonstration, different domains supported a number of South-Bound Interfaces (SBIs) with the Domain controller, including vendor-specific, standard OpenFlow version 1.3, and OpenFlow with optical extensions. The use of a common Service API allowed the same application to be tested across these heterogeneous domains.

Similarly, the Topology API allows applications to understand the connectivity available in the network.  A common Topology API allows a variety of applications to access network topology information, enabling support for new constraints and service criteria.

The Global Transport SDN demonstration implemented a prototype Topology API. Different domains exported their topology information enabling path computation to be performed outside of the controller.  These paths could then be requested using the Service API.  Additionally, the Service API responses had references to links and nodes in the topology, enabling the activated path to be shown.

Leadership Elections

The Forum conducted its annual leadership election with Doug Zuckerman of Applied Communication Sciences and Junjie Li with China Telecom elected to the OIF board of directors for one-year terms. Officers re-elected to two-year terms include Dave Brown of Alcatel-Lucent, vice president of marketing; Dave Stauffer, of Kandou Bus, secretary/treasurer; John McDonough, NEC Corp of America, vice president; and Torsten Wuth, of Coriant, Physical Layer User Group working group chair.
