Abstract
The hybrid types of traffic containing traditional data and multimedia streams are delivered in networks. Besides the Best Effort service, Internet has to supply other different services to various types of traffic with multiple priorities. DiffServ architecture is considered to be the promising Internet framework meeting QoS requirements. One of crucial elements in DiffServ is its network node scheme. In this paper, we propose a novel scheme which combines dynamic buffer management with active queue management to assist routers in provisioning loss differentiated services. In order to support several levels of different traffic classes, we extend a dynamic threshold buffer management method in the case of multiple loss priorities. We detail the implementation of the scheme on routers. Simulation results confirmed that our scheme is able to adapt to load changing conditions and offer different guarantees for hybrid traffic flows in terms of their loss priorities.
