<p>An automatic discovering method and device for the client layer link adapt to an optical transmission network. The method comprises the steps of: transmitting the client layer Traffic Engineering (TE) link objects of an ingress node by a connection setup request message to an egress node during the service layer connection setup, and the egress node obtaining the client layer TE link corresponding to the service layer connection by selecting, then returning the client layer TE link to the ingress node by a connection setup respond message, and storing the client layer TE link in the ingress node and the egress node respectively then publishing it to each node in the network by the route protocol, so as to realize the automatic discovering of the client layer link. The device located in the nodes of the network includes a request message transmission unit and a request message reception unit, and still includes a respond message transmission unit and a respond message reception unit.</p> |
