The 2016 Ethernet Roadmap

Authors: John D'Ambrosia (Ethernet Alliance)

BP Abstract: Ethernet Alliance developed the 2016 Ethernet Roadmap as a good overview of the latest developments in Ethernet standards. This BoF will discuss the latest developments in Ethernet and show how 2.5, 5 and 25GbE standards were completed in 2016 while 50 and 200GbE standards are under development with 400GbE. The BoF will also discuss Flex Ethernet that is considered next-generation LAG and creates speeds from 75GbE to 500GbE. The BoF will discuss the latest developments in new optical module form factors for 100-400GbE including the microQSFP, QSFP-DD and on-board optics (OBO). Physical copies of the roadmap will be handed out.

Long Description: This exciting and interactive BOF will discuss the latest developments in Ethernet that are summarized in the 2016 Ethernet Roadmap. This roadmap is an overview of the latest Ethernet technologies that are being developed and deployed. The BOF will discuss how Ethernet is driving high performance computing (HPC) to new levels of performance. Ethernet is the most popular type of networking technology deployed today and is going through exponential changes. Free copies of the 2016 Ethernet Roadmap will be handed out to attendees. The roadmap is full of excellent graphics that will be used in the BOF presentation. The BOF will educate the audience about Ethernet and leave time for questions and answers from the audience. In early 2016, six new Ethernet were being developed in IEEE. While it took 30 years to develop the first six speeds of Ethernet, Ethernet is diversifying rapidly to higher speeds such as 200GbE and 400GbE and cost-optimized speeds such as 2.5GbE and 5GbE. The lower speeds are optimized for sensors and Ethernet-based hard disk drives while the higher speeds are designed for routers and high performance switches. The BOF will discuss the latest developments in interconnecting data centers. Ethernet is the basis for most traffic over the Internet and optical transport networks (OTN). To optimize the traffic for these long distance links, Flexible Ethernet (FlexE) is being developed that interfaces to next generation OTN and dense wavelength division multiplexing (DWDM) systems. FlexE enables muxing of various lower speed links into very efficient high bandwidth streams. HPC data centers require high bandwidth connections to other data centers and end users that could use the benefits of FlexE. Another hot topic in Ethernet is the shift to 50Gb/s serial lanes. Signaling rates are shifting from 10Gb/s to 25Gb/s now and will shift to 50Gb/s/lane starting in 2018. 50G signaling will create a new generation with 50G SFP+ connections to servers, 100GbE (2X50G) and 200GbE (4X50G) for switches and 400GbE (8X50G) for routers. IEEE is developing new speeds and interfaces to take advantage of this new technology. New Ethernet interfaces will also be discussed that include copper and optical modules. New 400GbE modules such as the CFP8, QSFP-DD and on-board-optics (OBO) will enable low cost 400GbE. The QSFP-DD fits 8 lanes in the size of the QSFP to support very high bandwidth density switching. The micro-QSFP is another new four-lane module that can pack lots of bandwidth into the size of an SFP+ module. The BOF will discuss how these interfaces will be used to increase performance per bit. The Ethernet Alliance is the voice of Ethernet and HPC is built around Ethernet. This BOF will discuss the best use of Ethernet in HPC and offer a question and answer period. The Ethernet Alliance will use social media to promote the talk and give multiple interviews to press and analysts at the event.
