Abstract
One example embodiment of the method includes receiving first control packets, by a first node, from a source node. The first control packets indicate the status of the source node. Whether the source node is operational and if a connection path between the first node and the source node is operational is determined based on the received first control packets. The method further includes sending a second control packet to a downstream node if the source node is non-operational, or the connection is non-operational. The second control packet includes at least one value indicating the source node is unreliable.
