Congestion control algorithms for non TCPtraffic

Abstract

In the recent era Internet rules the world. Joined by a wide array ofelectronic, remote, and optical innovations, this network of networks consistsof private, public, scholastic, business and government networks of local toworldwide scope.Therefore it is required to find ways and means to avoid orto manage congestion for animportant period of time. The former is thecongestion avoidance mechanism that is proactive in nature and latter is thecongestion control mechanism which is reactive in nature.TransmissionControl Protocol (TCP)flows keep increasing the number of packets theycanplace on outgoing communication channels untilthey detect congestion. Whencongestion is detected, theydecrease their transmission rates significantly. Inthis manner,good fair share of bandwidth is attained by TCP flows. Today sinternet traffic not only consists of responsive flows but also unresponsiveflows in dominance. Whilein congestion, responsive flows decrease theirtransmission rates, on the other hand, unresponsive flows never. Itresults inunfair share of bandwidth among TCP and Non TCP flows. Due to thedramaticallyincrease in the number of unresponsive flows in the Internet,theabove problem is more likely to occur. Hence it is necessary to find ways andmeans to protect responsive TCP flows from high rate unresponsive flows. newline
