Kevin Springborn: High Performance Networking @ Google

Event Details

This talk is an introduction to high performance networking concepts. We start with a quick discussion of the OS implications of ever increasing network speeds. Next, we describe a typical Google datacenter, as motivation for thinking about networking challenges at scale. We provide a brief overview of Linux’s general purpose network stack to highlight some opportunities for different tradeoffs. Finally, Remote Direct Memory Access (RDMA) is discussed in detail. libibverbs examples are used as exemplars for common concepts (out of band establishment, RMA, messaging, etc.).
