AN AUTONOMIC FLOW BASED PATH SELECTION METHOD FOR MULTI-HOMED NODES

摘要

In order to access the Internet ubiquitously, most of the devices are equipped with multiple radio interfaces. In this way, the multi-homed node can attach to multiple access networks through multiple communication paths simultaneously. Flow based path selection is typically needed for the user to be always best connected. Meanwhile, autonomic feature can be introduced into the path selection system. An autonomic flow based path selection system is proposed in this paper to autonomically and efficiently select the best communication path for the traffic flows of the multi-homed node. The generated routing rules can constrain specific traffic flow to certain communication path properly and simultaneously. In the end, the throughput of the multi-homed nodes is verified in our simulation scenario to evaluate the performance of the path selection method.
