COMPUTER SYSTEM, AND COMMUNICATION METHOD

Title:

COMPUTER SYSTEM, AND COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2012/133290

Kind Code:

A1

Abstract:

In a computer system according to the present invention, a controller uses an ARP response packet, the transmission source of which is the MAC address of a physical server corresponding to a target VIP address included in an ARP request packet from a terminal, to representatively respond to the ARP request packet from the terminal, thereby notifying the terminal of the MAC address of the physical server that is an access destination of the terminal. Also, the controller sets, to a switch, a flow entry that is transferred from the terminal and that specifies to transfer a received packet, the destination MAC address of which is the aforementioned MAC address, to a communication path leading to the aforementioned physical server. In this way, it is made possible to arbitrarily set a server, which is the access destination of a terminal, in a high-speed network environment, while suppressing the increase in cost.
