400GE: Hype, reality, something else? OFC 2017 video by Xilinx, Microsoft/Azure Networks, and Juniper explains all

To paraphrase Douglas Adams’ Hitchhikers Guide to the Galaxy: “400GE is fast. Really fast. You just won't believe how vastly, hugely, mind-bogglingly fast it is.”

 

Xilinx, Microsoft/Azure Networking, and Juniper held a 400GE panel at OFC 2017 that explored the realities of the 400GE ecosystems, deployment models and why the time for 400GE has arrived. The half-hour video below is from OFC 2017. Xilinx’s Mark Gustlin discusses the history of Ethernet from 10Mbps in the 1980s to today’s 400GE, including an explanation lower-speed variants and why they exist. It also provides technical explanations for why the 400GE IEEE technical specs look the way they do and what 400GE optical modules will look like as they evolve. Microsoft/Azure Networking’s Brad Booth describes what he expects Azure’s multi-campus, data-center networking architecture to look like in 2019 and how he expects 400GE to fit into that architecture. Finally, Juniper’s David Ofelt discusses how the 400GE development model has flipped: the hyperscale developers and system vendors are now driving the evolution and the carriers are following their lead. He also touches on the technical issues that have held up 400GE development and what happens when we max out on optical module density (we’re almost there).
