Modelling and analysis of routing and resource allocation techniques in multi-service networks

摘要

In this paper a novel call level model based on the extension of the classical Erlang multi-rate model for broadband integrated services networks in proposed. We use the model to study routing strategies in multi-service networks where service classes with/without Qos guarantees coexist. Examples or such networks include ATM and IP-based integrated networks. In ATM, the CBR and VBR service classes provide QoS guarantees, while the ABR and U?BR service classes are of the best effort type.
