Abstract
A multi-tenant system is realized by the Tunneling protocol. The multi-tenant system includes a server apparatus on which a virtual machine with tenant identification data operates; an equipment whose tenant identification data cannot be recognized; a plurality of switches configured to transfer a packet based on flow entries; and a controller configured to set the flow entries to the switches. The plurality of switches includes a first switch connected with the server apparatus and a second switch connected with the equipment. The second switch rewrites the header of the packet sent from and received by the equipment based on an address translation table. Thus, the equipment becomes available.
