Looking for a relatively painless overview of the current state of the art for high-speed Ethernet used in data centers and for telecom? You should take a look at this just-posted, 30-minute video of a panel discussion at OFC2017 titled “400GE from Hype to Reality.” The panel members included:
- Mark Gustlin, Principal System Architect at Xilinx (the moderator)
- Brad Booth, Microsoft Azure Networking
- David Ofelt, Juniper Networks
Gustlin starts by discussing the history of 400GbE’s development, starting with a study group organized in 2013. Today, the 400GbE spec is at draft 3.1 and the plan is to produce a final standard by December 2017.
Booth answers a very simple question in his talk: “”Yes, we ill” use 400GbE in the data center. He then proceeds to give a fairly detailed description of the data centers and networking used to create Microsoft’s Azure cloud-computing platform.
Ofelt describes the genesis of the 400GbE standard. Prior to 400G, says Ofelt, system vendors worked with end users (primarily telecom companies) to develop faster Ethernet standards. Once a standard appeared, ther would be a deployment ramp. Although 400GbE development started that way, the people building hyperscale data centers sort of took over and they want to deploy 400GbE at scale, ASAP.
Don’t be fooled by the title of this panel. There’s plenty of discussion about 25GbE through 100GbE and 200GbE as well, so if you’re needing a quick update on high-speed Ethernet’s status, this 30-minute video is for you.
