Test results for TC002 network latency
======================================
.. toctree::
:maxdepth: 2
Overview of test case
=====================
TC002 verifies that network latency is within acceptable boundaries when packets travel between hosts located on same or different compute blades.
Ping packets (ICMP protocol's mandatory ECHO_REQUEST datagram) are sent from host VM to target VM(s) to elicit ICMP ECHO_RESPONSE.
Metric: RTT (Round Trip Time)
Unit: ms
