Comparison and Analysis of Drop Tail and RED Queuing Methodology in PIM-DM Multicasting Network

The paper describes a Multicasting network using PIM-DM (Protocol Independent MulticastDense Mode) with two queuing algorithms Drop Tail and Random Early Detection (RED). A simulation environment is created in NS2 to analyse and contrast Drop Tail and RED for queue management on basis of drop out data packets in network. The experiment indicates better performance of RED by 13.7375% on the basis of reducing drop out data packets. The topology is created using TCL to simulate multicast network and graphs are generated in Tracegraph, to contrast the difference. Keywords— PIM-DM, Drop Tail, RED, Data Multicasting, NS2
