What is Barefoot Deep Insight?
Barefoot Deep InsightTM is the first to provide the four ground truths for every packet in the network
1 How did it get here? The sequence of devices the packet visited along its path.
2 Why is it here? The set of rules it matched upon at every device along the way.
3 How long was it delayed? The time it spent buffered in every switch, to the nanosecond.
4 Why was it delayed? The packets, flows and applications that the packet shared each queue with.
