Abstract: Due to the advent of technologies like Web 2.0, the Internet applications are able to support transmission 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 content. The quality of service in this case depends on congestion control. Many protocols have been introduced in order to supplement the standard TCP protocol in order to control network congestion. The CSFQ which was built for fair service with open – loop controller 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 resources and provide best service to end users. It monitors inter-domain traffic for trust relationships. Recently, Shi et al. presented a new mechanism known as Stable Token-Limited Congestion Control (STLCC) for controlling inter-domain congestion and improve network performance. In this paper we implement the STLCC mechanism. We built a prototype application that demonstrates the proof of concept. The experimental results revealed that the proposed application is able to control network congestion by controlling packet loss thus improving performance of network.
