Abstract
A method establishes a session across a plurality of nodes in a computer network using a load balancing technique. The plurality of nodes includes a current node and a plurality of next nodes, and each next hop node is coupled with the current node via a link. To determine the next hop node from the current node, the method determines the residual capacity of the links between the current node and the next nodes, and generates a random number. Next, the method selects one of the next nodes as a function of the random number and the respective residual capacities of the links between the current node and the next nodes. After selecting the one next hop node, the method directs packets for the session from the current node to the one selected next hop node.
