Abstract
A communication system includes: a control apparatus setting a process rule defining a process content appropriate to a received packet in a forwarding node; and a forwarding node comprising a packet process unit processing a received packet in accordance with the process rule. The forwarding node further includes: a request unit transmitting a process rule setting request to the control apparatus if the received packet is a first packet for which the process rule is not set; and a restriction unit restricting transmission of the setting request for a second packet satisfying a condition obtained from the first packet.
Claims19
A communication system, comprising:
- a control apparatus setting a process rule defining a process content appropriate to a received packet in a forwarding node;
- and
- at least one forwarding node, comprising:
- a packet process unit processing a received packet in accordance with the process rule;
- a request unit transmitting a process rule setting request to the control apparatus if the received packet is a first packet for which the process rule is not set;
- and
- a restriction unit restricting transmission of the setting request for a second packet satisfying a condition obtained from the first packet.
A forwarding node, comprising:
- a packet process unit processing a received packet in accordance with a process rule defining a process content appropriate to a received packet;
- a request unit transmitting a process rule setting request to the control apparatus with respect to a first packet, among the received packet(s), for which the process rule is not set;
- and
- a restriction unit restricting transmission of the setting request for a second packet satisfying a condition obtained from the first packet.
A received packet process method, comprising:
- transmitting, when processing a received packet in accordance with a process rule defining a process content appropriate to a received packet if no process rule matching the received packet is set, a process rule setting request to a predetermined control apparatus for a first packet for which the process rule is not set;
- and
- restricting transmission of the process rule setting request for a second packet satisfying a condition obtained from the first packet.
A computer-readable storage medium storing a program, causing a computer that is included in a forwarding node comprising a packet process unit processing a received packet in accordance with a process rule defining a process content appropriate to a received packet to execute:
- transmitting a process rule setting request to a predetermined control apparatus for a first packet for which the process rule is not set;
- and
- restricting the process rule setting request for a second packet satisfying a condition obtained from the first packet.
