Amin Vahdat explains Google's custom datacenter networking hardware, software-defined networking, and high bisection bandwidth architecture.

Open Networking Summits, Inc. (ONS) represents the industry's premier and only non-profit conference that brings together the entire networking ecosystem to discuss advances in software-defined networking (SDN), OpenFlow and network functions virtualization (NFV). With a mission to transform networking, the non-profit ONS is exclusively committed to bringing together the thought leaders, luminaries, creators, and innovators of SDN and OpenFlow to lead the development of the networks of tomorrow. Founded in 2011, ONS produces conferences that attract participants from around the world, who come to discuss, share and shape the future of networking. Through exhibitions, demonstrations, visionary talks, technology tutorials and networking opportunities, ONS helps facilitate the understanding and dialogues that drive the advancements and adoption of new networking technologies.

Why it's here

What people say. Highly recommended for its rare, detailed look into the scale and architecture of Google's internal network infrastructure.

On “What's the Best Cloud? Probably GCP”

If you're interested in datacenter networking, can't miss ONS. Amin Vahdat, the guy in charge of networking at Google, has keynoted the past two years, with hardware in 20151 and software in 20142. Mark Russinovich also spoke about Azure's SDN, but it doesn't come close to Amin's presentation. Every once in a while you'll hear some random spec from one of these companies, and it's always pretty surprising, but Amin's team has achieved 5 Petabit/s in bisectional bandwidth. It's more than surprising. 1 link to this video 2 link 3 link

On “Is the Network the Limit? Dealing with Weave, CoreOS and Azure”

Hi Joe :) Conveniently, Amin Vahdat recently shared some content publicly about why it should scale to lots of VMs: link to this video (And, to others, disclaimer: I work on some bits of GCE networking at Google)

On “Non-volatile Storage: CPUs no longer more performant than I/O devices”

The numbers in this are daunting, but I personally believe massively multi-core systems make the problem a lot less daunting than the article makes out. Core counts in big servers can get up over 100 per server for Intel (see Amazon's new EC2 offerings for public evidence of this). Intel's Xeon Phi series of processors offer core counts approaching ~300. Going to 300x takes the required latencies per request from microseconds up to the millisecond range. POWER systems can go even higher. Moreover, for many workloads that actually leverage this sort of compute you can do something horrifying with the new DRAM-addressable persistent storage: DMA directly from the NIC into block storage. Some (…

On “Google Compute Engine Incident #16015”

They switched to openflow on internal networks for this reason, deterministic: link to this video External network is BGP though and sounds like they didn't detect it until user reports hit. They can't predict the problem and there detection isn't working well either.

On “Espresso – Google’s peering edge architecture”

For some reason they didn't actually link to the talk, which I haven't watched, but presumably actually tries to start answering those questions. Quick search is showing the 2015 keynote that Amin gave, haven't found the 2017 one yet... 1 - 2015 ONS Keynote link to this video
