ICMP flood attacks is usually focused at precise servers or they may be random. It fundamentally consumes bandwidth to The purpose of exhaustion.

Most switches have some charge-limiting and ACL capability. Some switches offer automatic or program-wide fee limiting, targeted visitors shaping, delayed binding (TCP splicing), deep packet inspection and bogon filtering (bogus IP filtering) to detect and remediate DoS attacks as a result of computerized charge filtering and WAN Url failover and balancing.
