Abstract
Verifying a configuration of reconfigurable internal optical paths (970) in a wavelength selective optical switching WSS node (62) involves identifying which of several WSS subsystems (920, 950, 960) is coupled upstream of a first internal optical path based on detecting optical power distinctive of the upstream subsystem and carried to the downstream WSS subsystem. The detecting can be of a power of wavelengths used for traffic (110), or a power of optical noise when there is no traffic (120). A record is made of the identified configuration. The automated verification can be carried out without the conventional dedicated optical wavelengths or dedicated optical hardware for inserting such additional wavelengths dedicated to discovery, and without disrupting the traffic if upgrading a node. It can be controlled locally or by an NMS such as an SDN controller.
