Congestion is a problem that occurs on shared networks when multiple users contend for access to the same resources (bandwidth, buffers, and queues). Think about freeway congestion. Many vehicles enter the freeway without regard for impending or existing congestion. As more vehicles enter the freeway, congestion gets worse. Eventually, the on-ramps may back up, preventing vehicles from getting on at all. Congestion control in computer network is an important issue to be addressed. Various congestion protocols are used for avoiding congestion in network. The survey of congestion control protocols in network is important and necessary for smart transport system. This paper discusses the advantages/disadvantages and the applications of various con-gestion control protocols for wired/wireless networks. It ex-plores the motivation behind the designed, and traces the evolution of these congestion control protocols.
