• Telecommunication technologies are making relentless progress. In this circumstance, network cost must be evaluated to assess the effectiveness of emerging technologies. To do such a nevaluation efficiently, it is necessary to develop a software tool that can calculate the network cost independent of the employed technologies. This paper describes computational techniques used in developing such a software tool. First, the functional requirements are idengified to establish a flexible tool that is applicable to a wide range of technologies. One of the required functions is the function that computes the resource amount and the network cost from the given conditions auch as traffic demands, a cable duct network, multiplex hierarchy and the specifications of network elements employed. As this computing function, the paper proposes an appropriate path calassification scheme that enables us to evaluate the resource amount correctly when a service protection technique is applied to the target network. Namely, the proposed scheme yields evaluations that isolate the primary path route from the backup path route. This isolation is not always provided without classification. In addition, a classification of network elements is also derived for valid estimation of the necessary interface board number, which is a basis of estimating the required network element amount. This classification allows us to identify the exact points of path cross-connection and termination, which affects the number of interface boards. This paper presents the computing procedures that realize path grouping and an estimation of network elements using these classification schemes. Finally, the paper describes a prototype of the tool to confirm the feasibility and effectiveness of the proposed schemes.
