| Abstract | ||||
| Over the last few years computer networks have experienced an explosive growth, causing congestion collapse problem, where no data transfers through the network, the throughput drops to zero, the response time tends to infinity, and as a result causing performance degradation. Congestion is handled at the end systems using end-to-end congestion control protocols, and at the network routers using network-assistant congestion control strategies, active queue management techniques (AQM) for example. Differ from data applications which built on top of transmission control protocol (TCP), most real-time traffics, have been built on top of unreliable connectionless user datagram protocol (UDP), such as voice-over-IP or streaming video over the Internet, since real-time applications can accept loss more than delay and jitter. Buffer control techniques are used to manage the queue size, and to enforce approximate fairness among a large number of different internet flows by queue management and scheduling disciplines. In this paper a new class-based dynamic scheduling technique is proposed. With this proposed technique, quality of service (QoS) requirements can be provided for multimedia video and audio traffic as same as that for the best-effort TCP-based data traffic applications. Using the network simulator NS-2 the proposal is compared with the most well-known scheduling approaches. | ||||
