Efficiently Controlling the Traffic in Wireless Network

The Internet takes an central role in our communications infrastructure, the slow convergence of steering protocols after a network failure becomes a growing problem. To assure fast recovery from bond and node failures in IP networks, we present a new recovery scheme called Multiple Steering Pattern (MSP). MSP is based on keeping additional steering information in the routers, and allows packet ahead to continue on an alternative output bond immediately after the detection of a failure. Our proposed scheme guarantees recovery in all single failure scenarios, using a single mechanism to handle both bond and node failures, and without knowing the root cause of the failure. MSP is strictly connectionless, and assumes only destination based hop-by-hop ahead. It can be implemented with only minor changes to existing solutions. In this paper we present MSP, and analyze its performance with respect to scalability, backup path lengths, and load distribution after a failure.
