Performance Analysis on a BGP Network using Wireshark Analyzer

Abstract

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.

This study focused on the performance analysis of BGP when implemented in a network. The configuration of BGP was done using Graphical Network Simulator (GNS3). To test the performance of BGP in a network, Wireshark was used for this purpose. The Wireshark is a network packet analyzer where it can capture live packet data from a network interface and display packet with every detailed protocol information.

Performance details of the packet in terms of several parameters are used in this study namely: 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, all routers have the same packet length and packets captured. However, the packets captured between the first and last, the average packet/sec, Avg. packet size (bytes), Bytes, and Avg. bytes/sec differ in all the routers.
