Abstract
There is provided an information processing system using a controller and a switch, wherein the switch transmits a predetermined message to all controllers to be connected when it is determined that there is no flow entry for a packet from a terminal to be connected in a flow table, and the controller sets the flow entry for discarding the packet in the flow table of the switch with low priority when it is determined that the predetermined message received from the switch does not satisfy a predetermined condition.
Claims5
An information processing system using a controller and a switch, wherein:
- the switch transmits a predetermined message to all controllers to be connected when it is determined that there is no flow entry for a packet from a terminal to be connected in a flow table;
- and
- the controller sets the flow entry for discarding the packet in the flow table of the switch with low priority when it is determined that the predetermined message received from the switch does not satisfy a predetermined condition.
An SDN controller used in a network constructed by an SDN, wherein:
- the SDN controller receives, from a switch, a message indicating that there is no flow entry for a packet from a terminal connected to the switch in a flow table;
- and
- the SDN controller sets the flow entry for discarding the packet in the flow table of the switch with low priority when it is determined that the message received from the switch does not satisfy a predetermined condition.
A switch used in a network constructed by an SDN, wherein
- the switch transmits a predetermined message to all controllers to be connected when it is determined that there is no flow entry for a packet from a terminal to be connected in a flow table;
- the switch receives, from the controller, a flow entry with low priority for discarding the packet when the controller determines that the message does not satisfy a predetermined condition;
- and
- the switch sets the received flow entry in the flow table.
