Internet real-time users are often confronted with network congestive messages such at "network busy, try later' due to the limitations and constraints of its TCP/IP traffic management protocols to support real-time applications. Four about a decade now, research effort has been directed on the extension of the TCP/IP protocol to fully support and grant the quality required by multimedia applications. Outcome of such extensions led to the proposition of Differentiated Service platforms [1] where users' expectations could be granted relative to agreed traffic profiles at the routers. A key requirement for such paradigm to work effectively is the application of differential packet scheduling and buffer admission mechanisms at the routers from source to destination. Thus, the Internet Engineering Task Force {IElF), through its request for comment for attaining OoS is searching for better algorithm to achieve OoS, maximize the use of scarce resources, minimize packet delay, loss rate and improve fairness in the network. Having studied various buffer management and scheduling processes from various Internet quality of service researchers in [2,3,4, 5 and 6], we present a modified quality of service-based traffic metering and admission logic, termed a revised token bucket traffic policer for the Internet router. The algorithm followed the traffic management propositions by the IETF and came out with better network performance in terms of packet loss rate and throughput. We carried out the simulation using C# a programming language tool and. We evaluate the performance of our algorithm with the former logic of a token bucket meter and observed that traffic sources and future real-time Internet service providers will receive fairer treatment when few packets are droStaff pped. This will consequentially improve the reliance of e-mobile providers on the Internet.
