Resilient Recursive Routing (R3) Towards Robust High Performance Networking

摘要

Research will test the hypothesis that the R3 routing architecture can be used to provide robust networking with reasonable levels of mobility. The hypothesis will be tested by using a network simulation tool (OPNET) to measure the performance of a network of static and mobile nodes and emulated wireless links. The goal is not to simulate the wireless environment but to model the impact of mobility on routing over such an environment. The simulations will cover: --Intermittent links --Links of widely varying capacities --Changing topologies as a result of reasonable mobility in our context this is defined as localized mobility as far as the logical network abstraction is concerned, which will be mapped to real node mobility in a wireless environment --Controlled changeovers from old to new topologies, and -- The impact of inconsistent network information Performance comparisons based on measures such as throughput, delay and packet loss will be made between R3 and IS-IS in dealing with reasonable levels of mobility. The goal will be to show that R3 can provide a significantly more robust mobile networking infrastructure than is possible with existing SPF based algorithms.
