SYSTEMS AND METHODS FOR TESTING DATA LINK CONNECTIVITY OF AN OPTICAL NETWORK EMPLOYING TRANSPARENT OPTICAL NODES

摘要

A method for testing data link connectivity of an optical network includes selecting a testing topology of the optical network, the selected testing topology including an initiator node, one or more end nodes, and one or more transparent optical nodes coupled therebetween, each of the one or more transparent optical nodes having a plurality of incoming ports and a plurality of outgoing ports. The method further includes setting each of the transparent optical nodes in a first switch state and transmitting a test message from the initiator node from a first predetermined outgoing port of the initiator node. The method further includes receiving the test message on an incoming port of the end node and detecting, for each transparent optical node, at which input port, which output port, or which input and output ports the test message is present. The input-output port mapping of the selected testing topology for the selected switched state can then be determined.
