摘要：: <p>A method for processing information of a Traffic Engineering (TE) link mainly includes: acquiring at least one protection attribute type of a TE link and operation state information corresponding to each protection attribute type; and distributing the acquired at least one protection attribute type of a TE link and the operation state information corresponding to each protection attribute type in a network. With the method in accordance with embodiments of the present invention, a control plane is enabled to reflect a change in the operation state of resources of a TE link with a certain protection attribute in time, enabling the network to establish a service connection meeting a particular demand for protection grade according to the newest operation state of the resources of the TE link, or trigger a rerouting optimization processing for an existing service connection.</p>
