NETWORK SYSTEM, MACHINE ALLOCATION DEVICE AND MACHINE ALLOCATION METHOD

摘要

There is provided a load distribution function that enables an application of a user to be freely allocated to a machine even if an address of a terminal or the application used by the user is duplicated between VPNs for each user. An access detector of a machine allocation device detects a start packet from received communication packets, and determines the type of the start packet and the type of the application used by the terminal. A machine allocation manager determines a machine on which the determined application operates, and operates the machine. A network manager configures a user virtual network on a second virtual network between the determined machine and the machine allocation device.

1. A network system coupled to a first physical network and providing a service to a device coupled to the first physical network,
the network system comprising a second physical network coupling to one or more physical computers; the network system, for each user using the device, being configured to: specify a first virtual network for the user, the first virtual network being configured on the first physical network; specify one or more virtual machines generated on the physical computer, the virtual machine running an application providing the service to the device; specify a second virtual network for the user on the second physical network, the second virtual network being coupled to the one or more virtual machines specified; and generate a private network for the user, by determining an association between the first virtual network, the second virtual network and the virtual machine.
