Gudavalli Venkata Sita, MD.John Saida 03 6 Legacy networks are often designed to operate with simple singlepath routing like the shortest path which is known to be throughput sub optimal On the other hand previously proposed throughput optimal policies ie back pressure require every device in the network to make dynamic routing decisions In this paper we study an overlay architecture for dynamic routing such that only a subset of devices overlay nodes need to make the dynamic routing decisions We determine the essential collection of nodes that must bifurcate traffic for achieving the maximum multicommodity network throughput Copyright (c) World Journal of Pharmaceutical Seiences.
