Abstract:
1. A computer system comprising: a controller; a plurality of switches, each of which performs a relay operation which is defined in a flow entry set by said controller, to a packet conforming to the flow entry; and a plurality of nodes which communicate through any of said plurality of switches, wherein said controller sets a destination address as a rule of the flow entry and sets transfer processing to a destination node as an action of the flow entry, and wherein each of said plurality of switches transfers the packet containing the destination address, to said destination node based on the flow entry set to said switch, regardless of a transmission source address of the packet, wherein said controller acquires a first MAC (Media Access Control) address of a first node of said plurality of nodes in response to a first ARP (Address Resolution Protocol) request from said first node, and sets the first MAC address to each of said plurality of switches as the rule of the flow entry.
