A METHOD AND APPARATUS FOR DISTRIBUTING LABELS IN A LABEL DISTRIBUTION PROTOCOL MULTICAST NETWORK

摘要

A method of distributing labels in a label distribution protocol multicast network having a root node and at least one leaf node comprises the steps, performed at a receiving node, of receiving a label and path vector from a distributing node, carrying out loop or convergence detection from the received path vector and, if convergence or no loop is detected, sending a receiving node label and path vector to its nexthop node in the network.
