Scalable QoS Provisioning for Intra-Domain Mobility

Intra-Domain Mobility Management Protocol (JUMP) has been recently proposed as a protocol for managing IP mobility within a cellular access network. This paper investigates the scalability performance of IDMP's Quality of Service (QoS) framework, which uses a modified form of the Differentiated Services architecture, with a centralized Bandwidth Broker (BB) performing admission control and resource provisioning for different traffic classes. The theoretical analysis show that requests for bandwidth reservation due to intra-domain mobility should be controlled to alleviate the processing burden at the BB. Accordingly, we propose a scalable bandwidth reservation scheme. By reserving the bandwidth in trunk instead of on perhost basis, QoS-related signaling load and handoff latency can be reduced significantly.
