Abstract :
A modified version of the Orwell protocol is presented. While this method preserves all the basic features, it introduces the concept of the surplus cell. These surplus cells enhance the performance of the network for class-2 traffic as well as those of the enhancement data in two-layer coded video by reducing the queuing delays. It is shown that the new method improves the delay characteristics of real-time services under mid-to-high traffic loads
