Abstract
An apparatus comprising a network node configured to communicate with a plurality of other network nodes via one or more logic links using protocol independent multicast (PIM), wherein the network node is further configured to transmit a PIM message comprising quality of service (QoS) data to at least one of the other network nodes. Also disclosed is a method comprising receiving, by a first network node, a first PIM join message comprising QoS data from a second network node, wherein the second network node is downstream from the first network node. Also disclosed is a method comprising: sending, by a first network node, a first PIM message comprising QoS data to a second network node, wherein the second network node is upstream from the first network node.
