- Abstract
- The differentiated service architecture is based on a simple model by applying a per-class service in the core node of the network. However, due to the simplified network behavior, the network structure and provisioning were more complicated. If a service provider wants the dynamic provisioning or better bandwidth guarantee, signaling protocol with QoS parameters or admission control method should be deployed in DiffServ network. However, these methods increase the complexity. Therefore, we propose the dynamic provisioning mechanism based on the centralized bandwidth broker and distributed measurement based admission control and movable boundary bandwidth management to support heterogeneous QoS requirements in DiffServ networks.
