Title:
NETWORK INTEGRATION DEVICE, NETWORK INTEGRATION METHOD, AND NETWORK INTEGRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/140507
Kind Code:
A1
Abstract:
An objective of the present invention is to implement multiple scaled logical networks when logically segmenting a network by a scaled logical network technology with respect to a virtualization environment. A network integration system (1) comprises a plurality of physical hosts (100), and an administration server (300). Virtual machines (104) and a virtual switch (103) are deployed upon a physical host (100). The virtual switch (103) tunnels a broadcast communication between the virtual machines (104) for each scaled logical network. The administration server (300) further comprises: a machine administration unit (311) which administers the deployment of the virtual machines (104); and a logical network administration unit (312) which, periodically and when the machine administration unit (311) changes the deployment of the virtual machines (104), if it is determined that it is possible to integrate and transmit the broadcast communications of the scaled logical networks with which the changed virtual machines (104) are associated, controls the virtual switch (103) to integrate the broadcast communications.
