Definition
Congestion appears in an interconnection network when intense traffic clogs any number of internal network paths, thus slowing down traffic flowing. Congestion management refers to any strategy focused on avoiding, reducing, or eliminating network congestion and/or its negative impact on network performance.
Discussion
Introduction
Congestion is a phenomenon that may dramatically degrade network performance. Congestion situations may actually appear in both computer communication networks (like the Internet) and interconnection networks of parallel computing systems. In the former, packet dropping is allowed (“lossy” networks), thus congestion is not a critical problem as congested packets can be discarded. Nevertheless, congestion should be avoided because dropped packets have consumed bandwidth, thus wasting it, and packet retransmissions significantly increase individual packet latency. In the latter, on the contrary, packets usually can not be...
