Abstract
The invention provides a method and device for verify link attributes in a node of an Automatically Switched Optical Network. In the Automatically Switched Optical Network, the node and another node are connected to a first port and a second port of one bidirectional link respectively, and the bidirectional link is divided into a first unidirectional link from the first port to the second port and a second unidirectional link from the second port to the first port. The method comprising the steps of: configuring a plurality of link attributes of the first unidirectional link in the node; receiving in the node a plurality of link attributes of the second unidirectional link configured in the another node from the another node; and comparing in the node the plurality of link attributes of the first unidirectional link with the received plurality of link attributes of the second unidirectional link respectively to check whether they match each other.
