<P>PROBLEM TO BE SOLVED: To construct an operation system which is capable of easily operating routes with guaranteed quality only by constructing an optical communication network with an efficient transmission system having a necessary minimum function in which quality guarantee for an unavailing route has been removed. <P>SOLUTION: An operation system acquires transmission specification classification information and association information of that information and a node constituent component or communication path pattern from a transmission information DB, and sets a communication path by transmitting, to an optical node device, control message including information acquired from the transmission information DB, a node constituent element according to transmission specification type information, and connecting a transmission system. That is, regarding a DB recording transmission specification and transmission system type, a DB referred to when a communication network is built and a DB referred to when a communication network is operated are made common, a communication network is built such that a DB facility is not become excess at the construction of a network, and the DB which is referred to at operation is clear in relationship between a route pattern and transmission specification. <P>COPYRIGHT: (C)2012,JPO&INPIT |
