<p><P>PROBLEM TO BE SOLVED: To enable a virtual large-capacity path to be related to a plurality of small-capacity paths contained in the virtual large-capacity path at the side of a lower network, and to control the virtual large-capacity path even to the lower network that does not correspond to the control of an original virtual large-capacity path. <P>SOLUTION: When the virtual large-capacity path is set or deleted, a path communication device requests a lower layer path communication device to set, delete, or change the virtual large-capacity path including the information on a plurality of communication paths contained in the virtual large-capacity path; and the lower layer path communication device sets, deletes, or changes a lower layer path corresponding to the virtual large-capacity path based on the communication on the plurality of communication paths included in the setting, deletion, or change request of the virtual large-capacity path. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
