TEF 2020: The Next Ethernet Rate

The Ethernet ecosystem is overdue to start considering an increase in the maximum port speed. The 802.3bs project completed work in 2017 and leveraged state of the art 50 Gb/s / lane SerDes technology with the new 8-lane front panel pluggable modules to enable 400 GbE. However, with the 802.3ck project now in mid-flight, which will standardize 100 Gb/s / lane electrical signaling, such 8 lane modules could be repurposed to enable an 800 GbE interface. Although this seems a logical next step, is this enough of a rate increase to satisfy end-user demand?

New datacenter workloads such as machine learning, AI, and streaming gaming services are driving ever increasing traffic loads, both machine to machine, as well as to the end user. The last major speed transition was 4 x from 100 GbE to 400GbE, which begs the question – why not 1.6 TbE rather than 800GbE as the next Ethernet rate?

The Ethernet Alliance will host a one-day Technology Exploration Forum (TEF) to focus on the trade-offs, use-cases and technology challenges surrounding the selection of what should be the next Ethernet rate. The Forum will bring together key experts from both the end user community as well as equipment and component manufacturers to discuss and debate these key issues with the goal of understanding end-user requirements and building consensus on what Ethernet’s next rate should be.

In addition to its own broad membership, which includes component vendors, system vendors, and end users, this event is open to non-Ethernet Alliance members.  Together, these constituencies will provide a diverse set of backgrounds, ensuring lively discussion and debate.

Panel Presentations

  • Market Need – The Next Ethernet Rate – This set of panel presentations will examine the drivers for the development of a higher rate Ethernet speed, from both a forward looking as well as historical perspective.
  • New Applications Driving Higher Bandwidths – A host of new applications including AI / ML, IoT, and 5G are driving the next wave of bandwidth growth in across all network sectors. How will these new workloads affect the demands on Ethernet, and does this indicate the need for a higher rate port?
  • Technical Feasibility I – Electrical Interfaces post 400GbE – Panelists will explore architectures and technical feasibility for next generation electrical interfaces. Topics will include approaches to deliver higher bandwidth per lane, and strategies for offsetting reduced physical reach at higher lane rates.
  • Technical Feasibility II – Next Generation Optical Interfaces Moderator – Optical interconnects are becoming one of the largest cost components of networking, with long development lead times. In this session, the trade-offs between technical and economic feasibility will be explored along with ecosystem readiness and alignment with end-user requirements.
