Abstract:
1. A method comprising: receiving information identifying one or more active virtual connections (VCs) of a plurality of active VCs available within a network and one or more IP subnets of a plurality of IP subnets configured on a plurality of nodes, wherein sending a second message comprising information identifying the first node and the second set of information to the second node; generating information identifying a global topology of the network, based upon the received information, wherein assigning one IP subnet of the plurality of IP subnets to one active VC of the plurality of active VCs, based upon the global topology of the network, wherein identifying which of the plurality of IP subnets is a most constrained IP subnet, based upon the information identifying the global topology, wherein assigning the most constrained of the IP subnets to one of the plurality of active VCs that satisfies connectivity requirements of the most constrained one of the IP subnets; and repeating said identifying which of the plurality of IP subnets is the most constrained IP subnet and said assigning the most constrained one of the IP subnets for additional ones of the plurality of IP subnets, until all of the plurality of IP subnets are assigned.
