Abstract:
At a controller of a network, said network comprising nodes and links between said nodes, each of said links having a known capacity, and where a set of routes is associated with each pair of said nodes, where a pair of said nodes includes a source node and a sink node, a method of distributing routing information to said nodes, said method comprising:receiving traffic information from said nodes, said traffic information including an indication of a traffic load from said source node to said sink node for said each pair of said nodes; based on said traffic information, determining a load-adaptation vector for a given pair of said nodes, said load-adaptation vector specifying an amount of a given traffic load for said given pair of said nodes allocated to each route in the set of routes associated with said given pair of said nodes; and transmitting said load-adaptation vector to each node of said given pair of nodes for use by said each node in making traffic routing decisions.
