In the further, the broadband networks based on ATM have to
support multiple classes of services with widely different
traffic characteristic and quality of services. In this thesis,
we investigate service classification, service mapping and QoS
allocation problems for multi-class ATM networks. The
classification algorithm group the service with similar
characteristic into classes. The classification results be used
to build the service mapping table which is store in the node to
speed up the call process procedure and simplify operation
control and management. We proposed three schemes to perform QoS
allocation and service mapping. Three QoS allocation schemes
named equal allocation, compensation allocation and proportional
allocation are consider. The simulation results show that for
multi-class network, the compensation and proportional
allocation schemes perform better than equal allocation scheme
in both blocking probability and bandwidth requirements.
