PTPmesh: Data Center Network Latency Measurements Using PTP
Authors: Diana Andreea Popescu, Andrew W. Moore.
Abstract
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 leverage 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 cloud providers, using
PTPd, an open-source software implementation of PTP.
