Congestion occurs ill a computer uetwork when the resource demandsexceed the capacity. Packets may be lost due to too lnuch queuingin the uetwork. During cougestion, the network throughput lnay dropand the path delay may become very high. A congestion control scheme}mlps the network to recover froln the congestion state. A congestionavoidance scheme allows a network to operate in the region of low delayand higfi throughput. Such schemes prevent a network from enteringtile cougested...
