Abstract:
1. In a network system comprising a plurality of nodes, a computer program product comprising computer executable instructions stored on a non-transitory medium of an upstream node that when executed by a processor cause the node to perform the following: advertise an upstream assigned label to a downstream node; receive a message from the downstream node; and assign the upstream assigned label when the received message confirms that no conflict with the upstream assigned label exists at the downstream node; or select a new upstream-assigned label or wait until indication is received that a label resource has become available when the received message confirms that a conflict with the upstream-assigned label exists at the downstream node, wherein the upstream-assigned label is selected from a predefined label range specific to the apparatus, and wherein the predefined label range is selected in part based on the Internet protocol (IP) address of the apparatus.
