Network failures continue to plague datacenter operators as their symptoms may not have direct correlation with where or why they occur.

Summary: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.
