Abstract
A computer system of the present invention includes a controller which sets a flow entry to each of a plurality of switches before a packet is forwarded from a plurality of nodes, and each of switches which transfers a reception packet which contains a destination address defined in the flow entry, to a destination node defined in the flow entry regardless of a transmission source address of the reception packet.
Claims10
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.

A communication method comprising:
- setting by a controller, a flow entry to each of a plurality of switches;
- performing by each of said plurality of switches, a relay operation defined in the flow entry to a packet conforming to the flow entry;
- and
- communicating between a source node and a destination node of a plurality of nodes through said plurality of switches,
- wherein said setting a flow entry comprises:
- setting by said controller, a destination address as a rule of the flow entry;
- and
- setting transfer processing destined to said destination node as an action of the flow entry, and
- wherein said communicating comprises:
- transferring by each of said plurality of switches, the packet containing the destination address to said destination node regardless of a transmission source address of the packet.
