Patent ID: 7123588

Claim:
In a communications network having a plurality of nodes, wherein pairs of said nodes are connected by one or more physical paths, each said path including one or more connected links, and wherein ownership of said links is divided among a plurality of entities and a market mechanism is provided for buying and selling of link capacity among said entities, a method for capacity management in said network by a given entity comprising the steps of: receiving at least two input parameters, said input parameters including a node-pair revenue parameter and a node-pair demand parameter; determining an expected revenue value for traffic offered for carriage by said given entity between a given node-pair, as a function of said node-pair revenue parameter and said node-pair demand parameter; in the event that said traffic offered for carriage between said given node-pair exceeds an available capacity of links owned by said given entity between said given node-pair, determining a provisional allocation of said offered traffic between capacity owned by said given entity and capacity owned by other entities; optimizing an objective function relating expected revenue and associated risk factors for said offered traffic and cost for said capacity owned by other entities, given alternative allocations of capacity between said given node-pair among links owned by said given entity and links owned by said other entities; and selecting a capacity allocation between said given node-pair that maximizes a weighted combination of expected revenue and risk.
