The Echo Protocol is a service in the Internet Protocol Suite defined in 1983 in RFC 862 by Jon Postel. It was originally proposed as a way to test and measure an IP network. A host may connect to a server that supports the Echo Protocol using the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP) on the well-known port ...

This may be used to detect that the remote host was effectively woken up, by repeating a new request after some delay to allow the host to resume its network services. If the host was just sleeping in low power active state, a single request wakes up that host just enough to allow its Echo Reply service to reply instantly if that service was ...

A ping flood is a simple denial-of-service attack where the attacker overwhelms the victim with ICMP "echo request" packets. [1] This is most effective by using the flood option of ping which sends ICMP packets as fast as possible without waiting for replies.
A displayed 'echo' is independent of 'duplex' (or any) telecommunications transmission protocol. Probably from technical ignorance, "half-duplex" and "full-duplex" are used as slang for 'local echo' (a/k/a echo on) and 'remote echo', respectively, as typically they accompany one another. Strictly incorrect, this causes confusion (see duplex ...
The dual unicast form is comparable with a regular ping: an ICMP echo request is sent to the patsy (a single host), which sends a single ICMP echo reply (a Smurf) back to the target (the single host in the source address). This type of attack has an amplification factor of 1, which means: just a single Smurf per ping.
