Performance Analysis of IPsec in Mobile IPv6 Scenarios

This paper describes an analysis of the performance overheads caused by the processing and space requirements of IPsec when protecting mobile IPv6 (MIPv6) signaling. Signaling between the mobile nodes and the home agent (HA) in a large-scale reference scenario is considered. The analysis is based on queuing theory and focuses on the overall utilization of the HA by the MIPv6 signaling processes as well as the total mean response time for a mobility process in the network. The results can assist network designers in finding the most appropriate security configuration for their specific network and mobility scenario.
