PingER, an acronym for Ping End-to-end Reporting, measures round-trip travel time of a packet of data between two nodes on the Internet.The PingER' Project uses a simple tool—the ping command—to get valuable insights into performance of the Internet backbone.
However, ping time may differ from experienced RTT with other protocols since the payload and priority associated with ICMP messages used by ping may differ from that of other traffic. End-to-end delay is the length of time it takes for a signal to travel in one direction and is often approximated as half the RTT.
End-to-end delay or one-way delay (OWD) refers to the time taken for a packet to be transmitted across a network from source to destination. It is a common term in IP network monitoring , and differs from round-trip time (RTT) in that only path in the one direction from source to destination is measured.
Ping operates by means of Internet Control Message Protocol (ICMP) packets. Pinging involves sending an ICMP echo request to the target host and waiting for an ICMP echo reply. The program reports errors, packet loss , and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard ...
Graphical depiction of contributions to network delay. Network delay is a design and performance characteristic of a telecommunications network.It specifies the latency for a bit of data to travel across the network from one communication endpoint to another.
When you get a message from a "MAILER-DAEMON" or a "Mail Delivery Subsystem" with a subject similar to "Failed Delivery," this means that an email you sent was undeliverable and has been bounced back to you.
The advantages of PathPing over ping and traceroute are that each node is pinged as the result of a single command, and that the behavior of nodes is studied over an extended time period, rather than the default ping sample of four messages or default traceroute single route trace. The disadvantage is that it takes a total of 25 seconds per hop ...
