Abstract
The quality of real-time applications is significantly affected by the delay of packets traversing a network. Some real-time applications set limits for acceptable network delay, and thus, a packet delayed longer than this limit before arriving at its destination is not only worthless but also harmful to the quality of the application because it may increase the queuing delay of other packets. Therefore, we propose an adaptive scheme for real-time applications in which such packets are discarded early. In this scheme, packets experiencing too much delay are discarded at intermediate nodes based on the delay limit for the application and the delay experienced by each packet. Such early discarding of packets is expected to improve the overall delay characteristics of real-time flows competing for network resources shared only by those flows. Simulation results showed that our scheme is effective.
