Vigil started with an ambitious goal: For every TCP retransmission in our data centers, we
wanted to pinpoint the network link that caused the packet drop that triggered the
retransmission with negligible diagnostic overhead or changes to the networking
infrastructure. This goal may sound like an overkill—after all, TCP is supposed to be able to
deal with a few packet losses. Packet losses might occur due to simple congestion instead of
network equipment failures. Even network failures might be transient. Above all, there is a
danger of drowning in a sea of data without generating any actionable intelligence.
