Abstract

Reduction in the delay of the network traffic is an important problem in the communication network. But, it becomes hard to bring down the delay with boosting the performance. The reason for this, to minimize the delay there must be a small queue but to reduce the packet drop there must have a large queue. In our proposed modified RED, the Explicit Congestion notification marked and network traffic packets will be dropped when only excess congestion occurs at router in TCP/IP network. The main aim is to provide better congestion control over the bursty traffic with maintaining the advantages of RED. Due to exponential increases in network traffic, to minimize the increasing packet loss rates, the IETF (Internet Engineering Task Force) consider the establishment of AQM techniques such as RED, REM. We use ns2 to simulate the modified RED and demonstrate that the modified RED gives better delay reduction and higher link utilization in case of bursty network traffic.
