  • NetPilot: Automating Datacenter Network Failure Mitigation

    ACM SIGCOMM

    Cloud scale data centers are huge, and leverage broad layers of cheap routers to achieve huge capacities. The downside is that network has many routers, and automation becomes essential for managing all aspects of the network.

  • Building Scalable Data Centers: BGP is the Better IGP

    Design choices, such as protocols & topology, for large scale (100k+ services) Web data centers have significant impact on scalability and operations of underlying networks. Such networks often host Hadoop-like compute clusters, which calls for topology providing large amount of bisection bandwidth. Consequently, to satisfy the requirement for intense east-west traffic, operators commonly choose some of Clos/Fat-tree topology variants.

    Design choices, such as protocols & topology, for large scale (100k+ services) Web data centers have significant impact on scalability and operations of underlying networks. Such networks often host Hadoop-like compute clusters, which calls for topology providing large amount of bisection bandwidth. Consequently, to satisfy the requirement for intense east-west traffic, operators commonly choose some of Clos/Fat-tree topology variants. Another prominent property of such environments is reliance on fixed form-factor, cheap commodity 1G/10G Ethernet switches to reduce capital expenditures. Both of these properties combined result in a network topology with very high link density and large number of switches – on the order of 10’s of thousands and thousands of elements respectively. Applying traditional data-center designs with large L2 domains, even leveraging features such as vPC/mLAG is not possible due to scalability issues. This situation calls for different design options

    “Dave is super-smart driven and extremely knowledgeable and innovative. Specifically, Dave was instrumental in defining the network architecture that reduced cost significantly and drove up reliability of Bing DCs. He is a great colleague and a real pleasure to work with - he is very collaborative but yet keeps the team focused on results and delivery. I'd welcome a chance to work with Dave again in the future.”
