Patent ID: 8254320

Claim:
A method, comprising: receiving, at a label edge router (LER), a pool of network addresses allocated to a mobility region in a mobility label based label switching network; allocating, at the LER, a range of mobility labels to the pool of network addresses, each network address, in the pool of network addresses, to be assigned to mobile nodes registered in the mobility region; determining, at the LER, a format associated with the range of mobility labels based on the pool of network addresses; determining, at the LER, a base label based on the format and the range of mobility labels; associating, at the LER, a first offset to a first network address, in the pool of network addresses, based on the base label and a position of the first network address within the pool of network addresses; associating, at the LER, a second offset to a second network address, in the pool of network addresses, based on the base label and a position of the second network address within the pool of network addresses, the second offset being different than the first offset and the second network address being different from the first network address; determining, at the LER, a first mobility label, of the range of mobility labels, for the first network address based on the first offset and a second mobility label, of the range of mobility labels, for the second network address based on the second offset, the second mobility label being different from the first mobility label; and distributing, by the LER, information associated with the pool of network addresses to other nodes in the mobility label based label switching network.
