Pingetests
Pingetests are a basic method for assessing the reachability and performance of a network path between a source host and one or more destination hosts. They typically use the Internet Control Message Protocol (ICMP) by sending echo request messages and waiting for echo replies. The resulting measurements usually include the round-trip time (RTT) for replies, the proportion of packets that do not reply (packet loss), and, in some tools, the variability of latency (jitter).
During a test, a host can perform a single probe or run a series of probes at
Uses include basic troubleshooting of network outages, initial assessment of new links, monitoring service availability, and
Limitations include that ICMP traffic is frequently deprioritized or blocked by firewalls, routers, or rate-limiting devices,
Ping, the original utility that popularized the concept, was developed in 1983 by Mike Muuss. The term
