Papers We Love Sept. 2018: 007: Democratically Finding The Cause of Packet Drops

Network failures continue to plague datacenter
operators as their symptoms may not have
direct correlation with where or why they occur. We
introduce 007, a lightweight, always-on diagnosis application
that can find problematic links and also
pinpoint problems for each TCP connection. 007 is
completely contained within the end host. During
its two month deployment in a tier-1 datacenter, it
detected every problem found by previously deployed
monitoring tools while also finding the sources of
other problems previously undetected.
