Congestion Propagation Among Routers in the Internet: In recent years, various non-linear phenomena of the Internet have been discovered. For instance, it is reported that congestion of a router propagates to neighboring routers like a wave. Several researches on congestion propagation among routers have been performed. However, in these researches, cause of congestion propagation and condition that...; Tags: Internet, Router, Congestion Propagation, Routers & Switches, Network Technology, Networking; White papers 2007-11-16
