METHOD, DEVICE AND SYSTEM FOR ISSUING THE ROUTING PROTOCOL MESSAGE AND COMPUTING THE ROUTING

摘要

A method, device and system for issuing the routing protocol message and computing the routing are provided by the embodiments of the present invention, which relate to the optical network communication technology and are able to solve the present problems that the time is too long for setting up the wavelength routing or rerouting and the efficiency using wavelength is lower. The method for issuing the routing protocol message comprises: obtaining the node information and the link information of the current node, said node information comprises the port cross capability information of the node, said link information comprises the wavelength limit information and the wavelength state information of each link connected with the node (S101); taking the obtained node information and the link information by the type-length-value (TLV) object of the routing protocol message, and issuing the routing protocol message in the network (S102).
