MULTI-LAYER NETWORK CONTROL METHOD AND DEVICE

摘要

[Problem] To provide a multi-layer network control method and device whereby it is possible to add a lower layer path in accordance with a path which is requested in an upper layer.;[Solution] With respect to controlling a multi-layer network formed from networks of a plurality of layers, virtual links (L901-L903) are generated in an upper layer network on the basis of topology information of a lower-order network. If at least one virtual link is included in a given path (F701) in the upper layer network, lower layer paths (L601, L602) corresponding to the virtual link are set in the lower layer network.

1. A multi-layer network control device that is a device to control a multi-layer network composed of a plurality of network layers, comprising:
a virtual link generation means for generating a virtual link in an upper layer network on the basis of topology information of a lower layer network; and a control means for, when at least one virtual link is included in a given path in the upper layer network, setting up a lower layer path corresponding to the virtual link to the lower layer network.
