Abstract :
In an effort to support resource reservation signalling IETF introduced the Next Step In Signalling (NSIS) suite as a generic framework. However, it causes significant overhead on the network and is not well-suited for mobile users. This paper presents a new mechanism to reduce the NSIS signalling overhead and resource reservation latency imposed by the node´s mobility in mobile networks. The proposed architecture comprises of two parts: the mobility management mechanism and resource reservation mechanism. The former contains the multi-layer local mobility anchor (LMA) in the domain and the latter comprises the pre-configured NSIS sessions between the upper layer LMA and the Lower layer intending to map all individual NSIS sessions belonging to the lower layer LMA in one NSIS session. The analytical framework is developed to evaluate the performance of the proposed architecture as compared to the basic operation of NSIS in the Proxy MIPv6 domain. Results obtained of the proposed scheme showed a significant reduction in the signalling overhead and resource reservation latency.
