ABSTRACT:
The present invention relates to a technique for a method of checking virtual-path-connection selection rights of fixed-length cell handling exchanges. For each of the virtual path connections, a second fixed-length cell handling exchange notifies, as first message information, a first fixed-length cell handling exchange of the status as to which of the first fixed-length cell handling exchange or the second fixed-length cell handling exchange has a selection right for the virtual path connection. The first fixed-length cell handling exchange that has received the first message information checks whether or not an inconsistency is present in the setting of the virtual-path-connection selection rights, and sends back to the second fixed-length cell handling exchange the result of the check, as second message information. This structure makes it possible to prevent the reduction in efficiency of use of virtual path connections and to efficiently and effectively utilize network resources.
