An Impact-Oriented Metric for Interference to Network Routing

The measurement of interference intensity is critical to design of network architecture and routing protocol. However, most existing metrics for interference to network routing are based on concrete attack behaviors and error generations, which have restricted their applicable range. In this paper, an impact-oriented metric is proposed for the measurement of interference to network routing. As to networks with capability of multi-path routing, traffic can bypass failed links or nodes by using local redundant resources. The metric check the extent to which the extra paths have been used. During this process, both the amount and the usage probability are taken into account.
