<p><P>PROBLEM TO BE SOLVED: To contribute to improvement of reliability of a communication network system which is to be constituted by coupling a plurality of ASs. <P>SOLUTION: In this path calculation apparatus which calculates a communication path, in the communication network system to be constituted by coupling the plurality of ASs, there are provided an AS path-prefix storage part 6 which stores a self-AS, to which a self-apparatus belongs, each network prefix about a cooperation destination AS in cooperation with the self-AS, and an AS path concerning the network prefix; and an AS path calculation part 10, which calculates an AS path with the least overlap as a communication path between the self-AS and the cooperation destination AS among the AS paths to be stored in the AS path-prefix storage part 6. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
