Performance Analysis of Protocol Independent Multicast (PIM)

Abstract

This research was conducted for the purpose of analyzing the performance of a network through the use of a combination of Protocol Independent Multicast (PIM ) and a unicast routing protocol which is the Open Shortest Path First (OSPF).A physical and logical topology was built using the Graphical Network Simulator (GNS3). A Class B address was subnetted into eight (8) subnets, each of which are accorded with the appropriate addresses. The Wireshark Network Protocol Analyzer was used for the analysis part to interpret the behavior and performance of the network with the protocol used. The performance of the network was analyzed on the basis of the following parameters: length of packet, total packets captured. packets captured between first and last packet, average packet per second, average packet size in bytes, number of bytes , and average bytes per second.

Based on the results, given the same number of packets captured, the links differ in the duration between the 1^st and last packet captured. It shows that the link R3 to R1 shows a considerable delay of 245.19 secs while R4 to R3 shows the fastest duration. The average packets/sec and the average size in terms of bytes are almost close to each others on all the links except R3 to R1. This is so because the duration is directly proportional to the packet size and bytes.
