a transmitter that transmits an address of the first virtual machine and an address of the second virtual machine to the router, and transmits an address of the router to the first virtual machine and the second virtual machine.
5. A management method comprising:
receiving, from a router that starts connecting to a data center through a first network, data concerning specification of a virtual machine for a user terminal in a second network connected to the router and data representing a request for connecting to a third network;
activating a first virtual machine satisfying the specification of the virtual machine on a computer in the data center;
activating a second virtual machine for connecting to the third network on a computer in the data center;
carrying out a setting of an address by which the user terminal connects to the third network, for the second virtual machine;
transmitting an address of the first virtual machine and an address of the second virtual machine to the router; and
transmitting an address of the router to the first virtual machine and the second virtual machine.
6. A computer-readable, non-transitory storage medium storing a program that causes a router relaying communication between a first network and a second network to execute a process, the process comprising:
upon connecting to a data center through the first network, reading out, from a data storage unit, data concerning specification of a virtual machine for a user terminal in the second network, and connection request data representing a connection request to a third network;
transmitting the data concerning the specification of the virtual machine and the data connection request data to the data center through the first network; and
upon receiving, from the data center, connection information including an address of a first virtual machine satisfying the specification of the virtual machine and an address of a second virtual machine that carries out a processing for connecting to the third network, carrying out a setting for communicating with the first virtual machine and the second virtual machine.
7. A router control method comprising:
upon connecting to a data center through a first network connected to a router, reading out, from a data storage unit, data concerning specification of a virtual machine for a user terminal in a second network connected to the router, and connection request data representing a connection request to a third network;
transmitting the data concerning the specification of the virtual machine and the data connection request data to the data center through the first network; and
upon receiving, from the data center, connection information including an address of a first virtual machine satisfying the specification of the virtual machine and an address of a second virtual machine that carries out a processing for connecting to the third network, carrying out a setting for communicating with the first virtual machine and the second virtual machine.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
