AN EFFECTIVE WAY OF PROTECTION AGAINST SHREW ATTACK IN COMPUTER NETWORKS

1 Shrew attack is a low rate burst which reduces the bandwidth of TCP flow and affects the performance of all TCP based protocols. A method has been suggested called as a shrew attack protection model that isolates attackers and identifies victims by keeping track of their drop rates and admit those packets which are having high priority for the queue. Shrew Attack Protection (SAP) has previously been demonstrated using network simulator ensuring the TCP sessions retain their bandwidth shares. In this paper the implementation of shrew attack model is done with router and switches and the results are analyzed to validate the performance of improvement of bandwidth after network attack.
