Inter-domain Mobility with LISP-MN -- A Performance Comparison with MIPv6

Abstract

In this work, we aim to evaluate Locator Identifier Separation Protocol-Mobile Node's (LISP-MN) performance in an inter-domain mobility scenario for both multi-interface and single interface Mobile Node (MN) with focus on throughput, handover delay, service disruption time and packet loss. To serve as the benchmark for performance, we compare LISP-MN with the IETF standardised MIPv6. We implement the 2 protocols on a laboratory test bed comprising all the nodes necessary for their operation. For multi-interface MNs, LISP-MN shows a better response in soft handover scenarios in terms of throughput and packet loss. MIPv6 on the other hand shows shorter handover delay with lower service disruption time in a hard handover scenario. Both protocols demonstrate poor performance for a single interface MN due to the long handover delay experienced. Although LISP-MN's handover control messages doubled that of MIPv6, our experiments show that it takes a similar time as MIPv6 to complete the handover message exchange.
