Many data center applications are latency-sensitive. Monitoring continuously the network latency and reacting to congestion on a network path is important to ensure that the applications performance does not suffer penalties. We show how to use the Precision Time Protocol (PTP) to infer network latency and packet loss in data centers, and we conduct network latency and packet loss measurements in data centers from different cloud providers, using PTPd, an open-source software implementation of PTP .

This is a practice talk for Diana’s presentation in MASCOTS 2017 .
