Abstract :
In this paper, we propose a backbone network that supports integrated as well as differentiated services (IntServ and DiffServ) through an 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 class environments. This algorithm can achieve the two objects of reliable delay bounded QoS provisioning and high resource utilization using flow-based traffic classification
