Fault Verification for an Unpaired Unidirectional Switched-Path

摘要

A communications network comprises a first node and a second node. The communications network further comprises an unpaired switched-path between the first and second nodes. Connectivity of the unpaired switched-path is tested by the first node transmitting a probe message along the unpaired switched-path and waiting to receive a probe message response as connectionless traffic from the second node. Also disclosed is a communications network component comprising logic that selectively verifies connectivity of a unidirectional communication path based on a probe message transmitted as connection-oriented traffic along the unidirectional communication path and a time limit in which to receive a probe message response as connectionless traffic. Also disclosed is a communications network component comprising at least one processor configured to implement a method. The method comprises selectively transmitting a probe message along a unidirectional connection-oriented path and waiting to receive a virtual local area network (VLAN)-based probe message response.
