Abstract
A computer program product comprising computer executable instructions stored on a non-transitory medium of an upstream node in a network system comprising a plurality of nodes that when executed by a processor cause the node to advertise an upstream assigned label to a downstream node, receive a message from the downstream node, and if the received message confirms that no conflict with the upstream assigned label exists at the downstream node, assign the upstream-assigned label, or if the received message confirms that a conflict with the upstream-assigned label exists at the downstream node, either select a new upstream-assigned label or wait until indication is received that the label resource has become available.
