Abstract :
In mesh networks, the proposed distributed algorithm sets up (in advance or dynamically) maximal-length (virtual-) circuits to bypass IP routers, reducing their size and power requirements, increasing efficiency, and improving network performance. By finding and setting up the optimal configuration of bypass circuits in an IP network, the algorithm: (i) minimizes the total number of expensive, high-speed IP router ports at network nodes; (ii) reduces the network energy requirements by shifting the maximum amount of traffic off IP routers and over to more energy-efficient optical bypass (virtual-) circuits; (iii) reduces the end-to-end packet latency by eliminating unnecessary queueing delays in IP routers; and (iv) reduces traffic congestion in IP routers by bypassing them whenever possible.
