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 2015[1] and software in 2014[2]. 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] [VIDEO] [2] [LINK] [3] [LINK]

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 [VIDEO]

They switched to openflow on internal networks for this reason, deterministic: [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.
