24.1 WAN acceleration overview
Long-delays and a high packet-loss rate are characteristic of WANs. Especially in TCP
communication, confirmation responses and congestion control for guaranteeing reliability
are affected, which sometimes results in a failure to satisfy expected packet forwarding
performance.
The service processor functionality is installed on both ends of a WAN on the TCP
communication path and uses its own TCP to communicate with each other. This
eliminates the long delays and high packet-loss rate for a communication node, and
enables improvements in both reliability and packet forwarding performance for TCP.
