FlexE is a technology for extending standard Ethernet PHYs to add support for bonding, sub-rating and channelization and also provides support for management channels and time synchronization. The FlexE 2.1 Implementation Agreement supports homogeneous collections of 50GbE, 100GbE, 200GbE and 400GbE PHYs. A common application is data-center interconnect over advanced coherent links. The FlexE framing mechanism is used as the basis for Recommendation ITU-T G.8312, Interfaces for the metro transport network. As IEEE 802.3 continues to develop standards for beyond 400 Gb/s Ethernet, it is anticipated that FlexE will be extended to operate over groups of greater than 400 Gb/s Ethernet PHYs.

FlexE 2.2
This is a maintenance release under development to incorporate the updates and corrections reflected in the FlexE 2.1 implementation guide.
