TRANSMISSION QUALITY DETERMINATION METHOD, TRANSMISSION PATH SELECTION METHOD AND NETWORK MANAGEMENT SYSTEM

摘要

There is provided a method of determining transmission quality of a path in an optical communication network system obtained by connecting a plurality of networks, the method including: acquiring a value representing transmission performance corresponding to a network condition of each of spans in the path in the optical communication network system; and determining the transmission quality of the path on the basis of the acquired value representing transmission performance corresponding to the network condition of each of spans.
