PING (ICMP echo/reply) Tests

A Ping packet is a simple ICMP packet that can be used to work out the round trip time of a pair of hosts. Although simplistic, an aggregation of ping results over a time period can give very useful insight into the state of the network and the changes in queues etc.

Number of pings on accuracy Tests to determine the optimal number of pings to send for various networks. Dell GigE b2b. Boston GigE b2b. Boston GigE MBNG.
Variation of packet size and interval between packets Dell GigE b2b.
Variation of packet size on latency Boston GigE b2b. Boston GigE MBNG
