Random Early Detection (RED) algorithm, a framework of active queue management (AQM), has been proposed in order to improve the performance of congestion routers due to the increased use of Internet. But, the basic problem of a lag between congestion's occurrence and its remedy remained. To overcome this problem of RED, Explicit Congestion Notification (ECN) proposed by the IETF that allows end-to-end...
This paper presents an overview of random early detection algorithm and differentiated services on ns2. In the present scenario of computer networks the traffic is increasing exponentially due to which packet losses are also increasing at a great rate. An active queue management in routers and gateways can potentially reduce packet loss rates in the Internet. In this paper we have proposed use of...
