      This is a talk that I gave at an internal VMware event called "Open
      Source Day" in February.  I prepared it as a kind of internal recognition
      of the ACM SOSR conference awarding Open
      vSwitch its Software Systems Award.  It goes over a history of Open
      vSwitch and the motivation behind it, factors that led to its success,
      and some of the project's failures and mixed results.

      view them to follow along.

      VMware Research High Bits is a podcast coming soon from VMware's research
      group.  This episode is a sneak preview of episode 1, with Lalith Suresh.
      Lalith is a researcher in the VMware Research Group who specializes in
      measurement, design, and implementation of large-scale networked and
      distributed systems.  Last year, Lalith published a blog
      entry with advice on how to build software systems for research, and
      then he followed up with a video with more
      details.  This episode interviews Lalith to learn more about his approach
      to building research systems.
    

    
      To learn more about Lalith's work, visit his VMware
      Research webpage or his personal blog Comfortably Geek, where you can also find
      his contact information.

      computer networking textbooks.  Mark Twain has been called the greatest
      humorist the United States has produced and the father of American
      literature.  This episode, the first collaboration among these celebrated
      authors, incorporates elements of the works of both [1, 2].

The Systems Approach, with Bruce Davie, Larry Peterson, and Mark Twain


      Bruce Davie and Larry Peterson talk about their Systems Approach series of
      books on computer networking.  These books began with the textbook Computer Networks: A
      Systems Approach, published in 1996.  After publishing the fifth
      edition in 2011, they took their book "open source" by making the text
      freely available on
      Github under a Creative Common license.  Now the original book is
      part of a series that also includes "micro-books" on SDN and 5G, with
      more books in preparation.  In this episode, Bruce and Larry talk about
      their motivations and future plans, including trying to rope your host
      into writing a book on Open vSwitch.

Computer Networks: A Systems Approach, with Bruce Davie and Larry Peterson


      Dmitry Yusupov submitted a talk to the Open vSwitch 2020 Fall Conference
      that we weren't able to fit into the schedule.  This podcast, recorded in
      December 2020, is based on the material that Dmitry presented in a video available on YouTube.
      The slides for Dmitry's talk are also
      available.
    

    
      The abstract for this talk is:
    

    
      
        OVSDB (management protocol RFC 7047) is a fundamental building block of
        modern SDN architecture based on OVN/OVS. OVSDB is the key component
        that is responsible for efficient scalability of large deployments,
        such as 1000+ node Kubernetes clusters when CNI function is OVN based.
      

      
        OVSDB was originally designed to store configuration for Open vSwitch
        daemon, however, it was later extended to be part of OVN architecture,
        with added RAFT clustering support and improved scale-out capabilities,
        such as efficient scale-out caches.
      

      
        This talk brings a question of scaling up OVSDB with introduction of
        OVSDB Query Optimizer using primary and alternate key indexing.  We
        will be also looking at OVSDB with Query Optimizer as high-performance
        Key-Value API interface and compare it to ETCD.
