Abstract
A communication node includes an entry memory capable of retaining a control information entry stipulating a processing to be applied to a packet received, a packet processor referencing the entry memory to process the packet received, and a request suppressing unit. Triggered by reception of a packet, the request suppressing unit requests a preset control apparatus to set a control information entry, and subsequently suppresses control information entry setting requests for a preset time for packets having a characteristic in common with the packet for which the control information entry setting request was made to the preset control apparatus.
Claims15
A communication node, comprising:
- an entry memory capable of retaining a control information entry stipulating a processing to be applied to a packet received;
- a packet processor referencing the entry memory to process the packet received;
- and
- a request suppressing unit that, triggered by reception of a packet, requests a preset control apparatus to set the control information entry and subsequently suppresses a control information entry setting request(s) for a preset time for such packet(s) having a characteristic in common with the packet for which the control information entry setting request was made to the preset control apparatus.
A control apparatus that controls a communication node including an entry memory capable of retaining a control information entry stipulating a processing to be applied to a packet received and a packet processor referencing the entry memory to process the packet received;
- wherein,
- the control apparatus includes a request suppressing unit that suppresses a control information entry setting request(s) from a controller of the communication node for a preset time as concerns a packet(s) having a characteristic in common with the packet for which the control information entry setting request was made from the communication node.
A communication system, comprising:
- a control apparatus that causes a control information entry to be set in a pertinent communication node in response to a control information entry setting request from a communication node, and the communication node(s);
- the communication node including:
- an entry memory capable of retaining the control information entry that stipulates a processing to be applied to a packet received;
- a packet processor that references the entry memory to process the packet received;
- and
- a request suppressing unit that, triggered by reception of a packet, requests a preset control apparatus to set the control information entry and subsequently suppresses a control information entry setting request(s) for a preset time for such packet(s) having a characteristic in common with the packet for which the control information entry setting request was made to the preset control apparatus.
A method for processing a packet comprising:
- requesting, in response to reception of a first packet, for which a control information entry setting request is to be made to a preset control apparatus, the preset control apparatus to set the control information entry;
- and
- dropping a second packet received within a preset time as from reception of the first packet in case the second packet has a characteristic in common with the first packet.
A method for controlling a communication node(s) comprising:
- a control apparatus configured to control the communication node(s) setting a control information entry in a pertinent communication node in response to a control information entry setting request from the communication node;
- and
- the control apparatus controlling the communication node so as to suppress the control information entry setting request(s) for a preset time as concerns a packet(s) having a characteristic in common with the packet for which the control information entry setting request was made.
A non-transitory computer-readable recording medium storing a program for causing a computer loaded on a communication node to perform:
- the processing of requesting, in response to reception of a first packet, for which a control information entry setting request is to be made to a preset control apparatus, the preset control apparatus to set a control information entry;
- and
- the processing of dropping a second packet received within a preset time as from reception of the first packet, in case the second packet has a characteristic in common with the first packet.
A non-transitory computer-readable recording medium storing a program for causing a computer loaded on a control apparatus to perform:
- the processing of setting, in response to a control information entry setting request from a communication node(s), a control information entry in a pertinent communication node;
- and
- the processing of controlling the communication node so as to suppress the control information entry setting request(s) for a preset time for a packet(s) having a characteristic in common with the packet for which the control information entry setting request was made.
