Abstract
In order to improve the link adjacency discovery in an Optical Transport Network, a method and related network nodes are provided. A first network node () has a first discovery agent () and a second network node () has a second discovery agent (). A discovery message () is transmitted from a first interface of the first network node () over one or more subsequent network links () to a second interface of the second network node (). The discovery message () contains information indicative of an discovery agent identifier associated with the first discovery agent () and of a termination connection point identifier associated with the first interface. In order to transmit the discovery message (), the first interface is configured to perform a tandem connection source function () using a reserved field in an overhead portion of signal frames to be transmitted. The second interface is configured to perform a Tandem Connection Monitoring function () on the same reserved field of received signal frames. The discovery message is sent using a Trail Trace Identifier (TT!) byte available in the reserved field.
