Method and apparatus for network latency performance measurement

摘要

A communication system (100) includes a network, a first application running on a first Host computer system (First Host) (102) coupled to the network, and a second application running on a second Host computer system (Second Host) (122) coupled to the network. The first application issues an Extended PING command (300) for sending an Extended ECHO message (380) from the First Host (102) into the network and directed to the second application in the Second Host (122). The second application in the Second Host (122), in response to receiving the Extended ECHO message (380), issues an Extended PING command (300) for sending an Extended ECHO reply message (380) into the network and directed to the first application to measure the full loop-back network latency of communicating a message application-to-application across the network.
