How can I tell when packet loss is affecting application behavior?
Application performance and throughput are influenced by many factors. Latency and packet loss have a profound effect on application performance. At the network level, application performance is limited by high latency (the effect of physical distance), jitter, packet loss, and congestion. At the application level, performance is further limited by natural behavior of application protocols (especially when faced with latency, jitter, packet loss, and congestion at the network level), that engage in excessive handshaking across the network links, and the serialization of the applications themselves. The solution is an effective WAN optimization framework/model.
