An ICMP flood, also called a ping or echo flood, is a denial-of-service technique that overwhelms a server with an unlimited stream of ping requests until legitimate users cannot receive responses. section 9.3
It is a volumetric attack against the infrastructure supporting an API, unlike application-layer attacks that exploit weaknesses such as unbounded data retrieval. Distributed variants use many origins to overwhelm services. section 9.3
Figure 9.14 A common DoS attack is ping flood. The goal of this attack is to overwhelm the server with an unlimited number of ping requests until it can no longer respond to requests from legitimate users.
The figure illustrates the failure mode: continuous ping requests consume server capacity until legitimate requests can no longer receive responses. section 9.3
