Title:
COMMUNICATION SYSTEM, COMMUNICATION CONTROL DEVICE, SWITCH DEVICE, COMMUNICATION CONTROL METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/230608
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve, in an open flow system using a general-purpose open flow switch, the same level of separation of network segments as in an L3 network. A communication system includes one or more switch devices and a communication control device. The switch devices transfer an address resolution request received at any of ports to the communication control device. The communication control device, upon reception of the address resolution request from any of the one or more of the switch devices, determines whether communication is permitted between logic segments to which a destination L3 address and a transmission source L3 address of the address resolution request respectively belong. If permitted, the communication control device designates a port associated with the destination L3 address, and transfers the address resolution request to the switch device associated with the destination L3 address. The switch device transmits the address resolution request received from the communication control device to the designated port.
