Abstract

Because of the admission control schemes in computer networks, in many multimedia communication scenarios it is not possible to get guaranteed quality of service for data transmission along the entire route from sender to receiver. In such cases scaling mechanisms can be used to overcome problems caused by resource congestion. Whenever resource bottlenecks are noticed, the multimedia traffic through these resources will be reduced for a limited time. The scaling scheme described in this paper uses mechanisms in the network layer to enable short delay times between detection of overload and the reduction of multimedia traffic. Network layer scaling allows priority-controlled regulation of multimedia traffic over network resources and adaptive handling of various paths and receivers. The monitoring and scaling strategies in the network layer and a prioritization scheme for multimedia stream packets are described.
