DETECTION OF REPAIR NODES IN NETWORKS

摘要

An apparatus and method for detection of repair nodes in a network. In one embodiment of the method, a first node generates a first message and a second message, wherein each of the first and second messages includes a first node identification (ID) that uniquely identifies the first node within a network. The first message includes a first path ID, wherein the first path ID corresponds to a first path through which the first node receives data packets of a stream. The second message includes a second path ID, wherein the second path ID corresponds to a second path through which the first node receives copies of the data packets. The first and second path IDs are distinct from each other. The first node transmits the first message upstream towards a root node for the stream via a first interface of the first node, and the first node transmits the second message upstream towards the root node via a second interface of the first node. The first and second interfaces are distinct from each other.

1. A method comprising:
a first node generating a first message and a second message, wherein each of the first and second messages comprises a first node identification (ID) that uniquely identifies the first node within a network domain; wherein the first message comprises a first path ID, wherein the first path ID corresponds to a first path through which the first node receives data packets of a stream; wherein the second message comprises a second path ID, wherein the second path ID corresponds to a second path through which the first node receives copies of the data packets; wherein the first and second path IDs are distinct from each other; the first node transmitting the first message upstream towards a root node for the stream via a first interface of the first node; the first node transmitting the second message upstream towards the root node via a second interface of the first node, wherein the first and second interfaces are distinct from each other.
