Some results on network mobility stress testing

In the last few years, several IP network mobility proposals have come to light. Nevertheless, as none of these solutions has been deployed, the respective studies on functional characteristics, performance, scalability and signalling load are mostly limited to simple proof-of-concept studies, in reduced-size lab settings and/or simulated environments, with low or modest traffic loads. This paper presents a comparative study of three network mobility solutions - one of them proposed by the authors - with which it is intended to evaluate their behaviour under heavy load traffic. The study resorts to a network mobility emulator developed by the authors. After performing an extensive set of tests, based on the obtained results we are able to conclude that the proposed network mobility solution has clear performance advantages over other, more traditional solutions, regardless the number of mobile nodes, packet inter-arrival times, number of nesting levels, and percentage of route-optimised flows.
