BANDWIDTH OPTIMIZATION BY TRAFFIC CLASSIFICATION INMULTIMEDIA BROADBAND NETWORKS

Abstract

In last decade, high bandwidth consumption of Peer to Peer (p2p) applications has
resulted increased bandwidth demandand service quality issues for critical business applications. Past
researchsuggestedthat traffic filtering of unwanted traffic and rate limitation of bandwidth hungry
applications can result in fair distribution and optimization of available bandwidth. In this context we
proposed and implemented internet traffic rate limiter and bandwidth optimizer based on FreeBSD(v8.1) operating system. The prioritized traffic flows throughput was increased by 5% and network latencywas reduced by 9.5%, which improved quality of service of prioritized traffic flows.
