Abstract :

The present day networks are meant for transmission of data, voice, multimedia applications, using packet switching and frame relays. With explosion in traffic, the earlier problem of proper routing, are proving to be lacking in a providing acceptable bonds of delay and errors, as network getting jammed due to traffic The current circuit switched and packet switched networks are suffering from the problem of extreme congestion and network crashing frequently. The demand for fast transfer of large volumes of data,. TCP, does not meet this demand because it favors reliability over Timeliness and fails to fully utilize the network capacity due to limitations of its conservative congestion control algorithm. The slow response of TCP in fast long distance networks leaves sizeable unused bandwidth in such networks. A large variety of TCP variants have been proposed to improve the connection’s throughput by adopting more aggressive congestion control algorithms. This article deals with different types of congestions algorithms and their roles in network.
