Abstract
A communication apparatus, comprises: a packet processing unit that processes, based on a processing rule set by a control apparatus, a packet that corresponds to the processing rule; a statistical value measurement unit that measures a statistical value with respect to the packet processing based on the processing rule; and a processing rule management unit that rewrites a processing content of the processing rule to a packet discarding process, if the statistical value for the processing rule exceeds a predetermined threshold.
Claims10
A communication apparatus, comprising:
- a packet processing unit that processes, based on a processing rule set by a control apparatus, a packet that matches the processing rule;
- a statistical value measurement unit that measures a statistical value with respect to the packet processing based on the processing rule;
- and
- a processing rule management unit that rewrites a processing content of the processing rule to a packet discarding process, if the statistical value for the processing rule exceeds a predetermined threshold.
A control apparatus, comprising:
- a management unit that generates a processing rule for a packet;
- and
- a communication unit that transmits the processing rule to a communication apparatus that processes based on the processing rule a packet that matches the processing rule, measures a statistical value with respect to the packet processing based on the processing rule, and rewrites a processing content of the processing rule to a packet discarding process if the statistical value for the packet processing rule exceeds a predetermined threshold.
A communication system, comprising:
- a control apparatus that generates a processing rule for a packet;
- and
- a communication apparatus, wherein
- the communication apparatus comprises:
- a packet processing unit that processes, based on the processing rule set by the control apparatus, a packet that matches the processing rule;
- a statistical value measurement unit that measures a statistical value with respect to the packet processing based on the processing rule;
- and
- a processing rule management unit that rewrites a processing content of the processing rule to a packet discarding process if the statistical value for the processing rule exceeds a predetermined threshold.
A communication control method, comprising:
- processing, based on a processing rule set by a control apparatus, a packet that matches the processing rule;
- measuring a statistical value with respect to the packet processing based on the processing rule;
- and
- rewriting a processing content of the processing rule to a packet discarding process if the statistical value for the packet processing exceeds a predetermined threshold.
A non-transitory computer-readable storage medium storing program, which causes a communication apparatus that processes based on a processing rule set by a control apparatus a packet that matches the processing rule to execute:
- measuring a statistical value with respect to the packet processing based on the processing rule;
- and
- rewriting a processing content of the processing rule to a packet discarding process if the statistical value for the packet processing rule exceeds a predetermined threshold.
