OIF Validates Maturity of Transport SDN APIs in 2020 Multi-Vendor Interoperability Demonstration – Results published in new white paper

Successful collaborative multi-vendor demo revealed high percentage of network operator-favored use cases supported and high product maturity, identified areas for interoperability improvement

Fremont, Calif. OIF today revealed the results of its 2020 Transport SDN Application Programming Interface (API) Interoperability Demonstration in a new white paper now available here. The white paper includes details on the test topology, testing methodology, technical specifications, use cases and findings.

The 2020 joint network operator, multi-vendor demo event focused on testing SDN-based programmability, control, and automation to support the industry to develop standard, robust, interoperable APIs for widescale adoption. The testing was conducted on a partially disaggregated open optical network architecture with operator-defined use cases.

“Interoperable transport SDN APIs are essential capabilities to enable open optical networks,” said Mauro Costa, Head of planning, strategy & architecture, Telia Company, a consulting network operator for this year’s demo. “International co-operations, like this one with OIF, allow the industry to progress at a high pace and Telia Company welcomes the opportunity offered by this interoperability demo. It reinforces that we are advancing in the right direction and that the maturity of the APIs implementation for optical SDN architecture is improving.”

The results of the 2020 demo were presented during a public read-out webinar held on 12 January 2021 in conjunction with Lightwave and on 19 January 2021 at a private, invitation-only virtual event jointly hosted by OIF and Telefónica. On-demand viewing of the Lightwave webinar is available here.

The interoperability testing involved three phases over ten weeks, Sept – Nov 2020, in Telefónica’s Madrid lab:

  • Phase 1: Open Networking Foundation (ONF) T-API NBI testing, Scope: ONF T-API v2.1.3 reference implementation agreement TR-547
  • Phase 2: Open terminals testing including discovery, provisioning, service de-activation and streaming telemetry
  • Phase 3: End-to-end disaggregation demo, Scope: evaluation and demonstration of end-to-end use cases

Findings and results of the testing include:

  • Vendor products demonstrate a high level of maturity and support of operator-favored use cases, based on T-API version 2.1.3 and OpenConfig APIs. Vendors have adopted the ONF 2.1.3 Reference Implementation Agreement (ONF TR-547) rapidly and with few deviations.
  • Inconsistent interpretation of the Internet Engineering Task Force (IETF) RESTCONF standard was one interoperability issue identified, especially standard authentication. Clarification to RESTCONF provisioning behavior and implementation scalability were also identified as issues.
  • A particularly good level of compliance to the OpenConfig models was demonstrated by implementations, however, some areas such as key exchange algorithms for IETF NETCONF and complex use cases for device provisioning and commissioning did generate issues.

Participating vendors included ADVA, Ciena, Cisco Systems, Infinera and Nokia. Network operator Telefónica hosted the demo. China Telecom, Telia Company and TELUS participated as consulting network operators.

OIF Completes Successful 2020 Joint Network Operator, Multi-Vendor Transport SDN API Interoperability Demonstration

Public webinar, read-out events planned for Q1 2021

Fremont, Calif.—December 2, 2020 – OIF today announced the completion of its multi-vendor 2020 Transport SDN Application Programming Interface (API) Interoperability Demonstration. To validate the benefits of transport SDN worldwide and transport network transformation for the 5G era, OIF members participated in a ten-week long interoperability testing exercise in Telefonica’s Madrid lab.

The testing focused on SDN-based programmability, control and automation — testing Layer 1 and Layer 0 OTN control using ONF T-API 2.1.3, with additional testing of OpenConfig device APIs for transport equipment in network-operator-defined use cases.

“Operators have demanded more open optical networks to enable flexibility, lower costs, and best-of-breed options,” said Scott Wilkinson, Lead Analyst at Cignal AI. “Standard management interfaces and multi-vendor interoperability are critical to open optical networks. The interoperability demonstration recently performed under the guidance of the OIF is a major step towards achieving those operator goals.”

Participating vendors included ADVA, Ciena, Cisco Systems, Infinera and Nokia. Network operator Telefonica hosted the demo. China Telecom, Telia and TELUS participated as consulting network operators.

“The successful completion of the OIF 2020 Transport SDN API interoperability demonstration is a significant milestone toward widespread SDN deployment in production networks,” said Arturo Mayoral, Telefónica Transport Global CTIO Unit – Technology Expert and Lead of Optical SDN strategy. “By aligning vendors for a shared purpose – interoperability – and testing multiple use cases, we’re fostering manageability and flexibility in the network to allow deployment of cloud-based services, meet dynamic bandwidth demands and accelerate transport network transformation for the 5G era.”

The much-anticipated results of the multi-vendor demonstration will be revealed during a public read-out webinar event being held in partnership with Lightwave, Tuesday 12 January 2021, 6:00-7:30am PST. Register for free here.

A private read-out event for demo participants and invited Network Operators is scheduled for Tuesday 19 January 2021.

OIF representatives will give presentations on the current status of the 2020 OIF Transport SDN API Interoperability Demonstration during the below events:

NGON & DCI World Digital Symposium – Friday 04 December 2020 – 20:00-20:15pm CET, OIF Speaker: Arturo Mayoral López de Lerma, Telefonica S.A

ECOC – Monday 07 December 2020 – 17:20-17:40pm CET, OIF Speaker: Arturo Mayoral López de Lerma, Telefonica S.A

Additionally, OIF developed an infographic to visually explain the 2020 Transport SDN API Interop Demo. Print and web-ready files can be downloaded here: https://1drv.ms/u/s!AgxJQTMC3jSUiIhCVZzu9vewlRGU0w?e=hl5D3C

A technical white paper and an executive summary of the demo result will be available in Q1 2021.

2020 Transport SDN Application Programming Interface (API) Interoperability Demonstration PR Boilerplate:

Leading the acceleration of the commercialization of transport SDN worldwide and transport network transformation for the 5G era, OIF will bring new use cases and deployment scenarios into Telefonica’s lab to test multi-vendor interoperability of Layer 1 and Layer 0 OTN control using ONF T-API 2.1.3 and OpenConfig Transport APIs. The 2020 Transport SDN Application Programming Interface (API) interoperability demonstration builds on OIF’s previous transport API requirements and interoperability demonstrations which substantiated T-API as the northbound interface (NBI) of choice, establishing a foundation for open, programmable networks that allow network operators to efficiently deliver dynamic multi-domain connectivity services to the market.
