25 Gigabit Ethernet call for interest

The following request for agenda time for a 25 Gigabit Ethernet call for interest has been received from Brad Booth. It will be discussed at the IEEE 802 LMSC March 2014 Plenary meeting in Beijing, China.

If you have any questions please get in touch with either or directly.

The use of 4x10G breakout via 40G interfaces has become very popular over the last few years in hyper-scale data centers. As these data centers prepare to transition to 100 Gigabit Ethernet, there is an expectation to use 100G (4 x 25 Gb/s) interfaces specified in IEEE P802.3bj and P802.3bm. What the industry is missing is the ability to provide a breakout solution that like 4x10G with 40G matches the single-lane line rate of 25 Gb/s. Where 4x10G could draw upon 10 Gigabit Ethernet, 4x25G has no ability to draw upon a 25 Gigabit Ethernet specification. This Call-for-Interest is a request for the formation of a study group to explore the enhancements required and market requirements to take advantage of interoperable interfaces specified in P802.3bj and P802.3bm to provide a single-lane 25 Gb/s Ethernet specification.

The call for interest will take place during the IEEE 802.3 Opening Plenary on the afternoon of Monday 17th March. A call for interest consensus building meeting has been scheduled to occur from 18:00 to 19:00 on the evening of Wednesday 19th March. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 20th March.
