Flow-based admission control for multiple service classes in the ATM-based MPLS network

In this paper, we propose the backbone network that supports the Integrated as well as Differentiated Services(Diffserv) through ATM shortcut connection or label swapping of MultiProtocol Label Switching(MPLS) using the capabilities of an underlying ATM network to realize Quality of Service(QoS). In the Label Edge Router(LER), we design a Diffserv mapping algorithm and integrated packet scheduler. Also we propose a flow-based admission control algorithm that is suitable for multiple service classes' environments. This algorithm can be achieved the two objects which are reliable delay bounded QoS provisioning and high resource utilization using flow-based traffic classification.
