摘要： A method, apparatus and system for advertising a routing protocol message and calculating a route are provided which solve the problems that the time of connection establishment or rerouting in wavelength routing is too long and that wavelength utilization efficiency is low. The method for advertising the routing protocol message includes: obtaining node information and link information of a node, in which the node information contains port cross-connection capability information of the node, and the link information contains wavelength restriction information and wavelength status information of each link connected to the node; carrying the obtained node information and link information in a Type-Length-Value object of a routing protocol message, and advertising the routing protocol message in the network.
