METHOD AND DEVICE FOR ROUTING AND OPTICAL COMMUNICATION NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a routing method for realizing flexible optical path networking on a distributed control network while fitting the state of a laid fiberlink.

SOLUTION: This routing method defines a deterioration parameter for transmission signal light in each link section, and a node that houses the link advertises the deterioration parameter to other nodes by utilizing a routing protocol used in an optical communication network. This method performs a route selection calculation including the propriety of the use of an identification and reproduction repeater on the basis of the deterioration parameter at optical path connection.
