A First Look at Data Center Network Conditions Through The Eyes of PTPmesh
Authors: Diana Andreea Popescu, Andrew W. Moore.
Abstract
Increased network latency and packets losses can
affect substantially application performance. Due to the scale
of data centers, custom network monitoring tools have been
developed to measure network latency and packet loss. In our
previous work, we used the Precision Time Protocol (PTP) to
measure one-way delay and to quantify packet loss ratios, and
we proposed PTPmesh as a cloud network monitoring tool. In
this work, we provide a better understanding on how to exploit
the measurement data offered by PTPmesh and present a detailed
analysis of PTPmesh measurements collected in ten data centers
from three cloud providers. Our findings reveal different latency,
latency variance and packet loss characteristics across data
centers. Through our analysis, we showcase the strengths and
limitations of PTPmesh as a cloud network monitoring tool. To
foster further research in this area, we make our dataset available
to the public.
