A New Proposal for Choosing a Deflection Link in a Deflection Network

In high-speed networks with greater connectivity, packets can be deflected through a sub-optimal path to reach the destination if the desired path is congested, failed or the buffer is full. However, in a combined store-and-forward and deflection network, packets are deflected when there is congestion in the network. For choosing a link for deflection in such a combined network, currently existing strategy considers only local information to the node in need to deflect a packet. In this paper, a new proposal has been introduced to select an outgoing link for deflection. Under the proposed strategy, packets are guaranteed to traverse through the best cost path available to the destination when they are deflected. Simulation shows better results than that of the existing strategy in terms of packet delivery, discard and average cost per delivered packet.
