Abstract
A communication system includes: a plurality of nodes; a first node transmitting a request for a processing rule for processing a first packet; and a control apparatus including a first unit determining a first processing rule corresponding to the first packet in response to the request and preliminarily determining a second processing rule corresponding to a second packet that relates to the first packet and a second unit notifying the first node of the first processing rule and notifying at least one of the plurality of nodes of the second processing rule.
Claims21
A communication system, comprising:
- a plurality of nodes;
- a first node transmitting a request for a processing rule for processing a first packet;
- and
- a control apparatus comprising a first unit determining a first processing rule corresponding to the first packet in response to the request and preliminarily determining a second processing rule corresponding to a second packet that relates to the first packet and a second unit notifying the first node of the first processing rule and notifying at least one of the plurality of nodes of the second processing rule.
A control apparatus, connected to a plurality of nodes, the control apparatus comprising:
- a unit receiving a request for a processing rule for processing a first packet from a first node;
- a first unit determining a first processing rule corresponding to the first packet in response to the request and preliminarily determining a second processing rule corresponding to a second packet that relates to the first packet;
- and
- a second unit notifying the first node of the first processing rule and notifying at least one of the plurality of nodes of the second processing rule.
A control method, executed by a control apparatus connected to a plurality of nodes, the control method comprising:
- receiving a request for a processing rule for processing a first packet from a first node;
- determining a first processing rule corresponding to the first packet in response to the request and preliminarily determining a second processing rule corresponding to a second packet that relates to the first packet;
- and
- notifying the first node of the first processing rule and notifying at least one of the plurality of nodes of the second processing rule.
