An object oriented toolkit for implementation oriented modeling of real-time multimedia communications

A comparative performance evaluation of network protocols and architectures necessitates theoretically evaluating and experimentally comparing the different architectures, protocols, topologies and technologies of the networks under the same operating conditions. A toolkit providing this facility may therefore be of great importance. In this paper a framework of traffic control to accommodate multimedia connections in a network is proposed. An approach based on the resource reservation protocol is implemented to reserve resources. It follows many novel design principles such as receiver initiated reservation, separating reservation from packet filtering, maintaining soft states in the network and modularity.
