A NOVEL TOKEN BASED APPROACH TOWARDS PACKET LOSS CONTROL

Abstract

Due to the advent of technologies like Web 2.0, the Internet applications are able to support transmis sion of multimedia content to end users. In such applications the transmission might result in packet loss as well. In this context, it is essential to have packet loss control mechanisms that can avoid deterioration of quality of services while rendering media rich cont ent. The quality of service in this case depends on congestion control. Many proto cols have been introduced in order to supplement th e standard TCP protocol in order to control network congestion. The CSFQ which was built for fair service with open ‐ loop contro ller has started deterioration in quality as P2P flows dominated Internet traffic of late. One of the closed loop congestion control known as Token-Based Congestion Control (TBCC) was able to restrict consuming resou rces and provide best service to end users. It moni tors inter-domain traffic for trust relationships. Recently, Shi et al. presented a new mechanism known as Stable Token-Limited Cong estion Control (STLCC) for controlling inter-domain congestion and improve net work performance. In this paper we implement the ST LCC mechanism. We built a prototype application that demonstrates the proof o f concept. The experimental results revealed that t he proposed application is able to control network congestion by controlling packet loss thus improving performance of network.
