Abstract
A communication method for identifying a packet flow based on a predetermined rule and processing a packet belonging to the identified packet flow, the communication method includes: setting in a first node a plurality of first rules that identify a plurality of packet flows, respectively; and setting in a second node a second rule that identifies the plurality of packet flows as a group.

A communication method for identifying packet flows based on predetermined rules and processing packets belonging to identified packet flows, the communication method comprising:
- setting, by a setting apparatus, in two first nodes, a plurality of first rules that identify a plurality of packet flows, respectively;
- and
- setting, in a second node, arranged between the two first nodes, a second rule that identifies the plurality of packet flows as a group,
- wherein the plurality of packet flows are flows between the two first nodes via the second node, and
- when the first and second nodes receive an unknown packet, the first and second nodes request the setting apparatus to set the corresponding first or second rule, and
- first nodes process a received packet based on the set first rule, and the second node processes a received packet belonging to one of the plurality of packet flows based on the set second rule.
A communication system for identifying packet flows based on predetermined rules and processing packets belonging to identified packet flows, the communication system comprising:
- a setting apparatus;
- two first nodes;
- and
- a second node arranged between the two first nodes,
- wherein the setting apparatus comprises:
- a first unit that sets, in the two first nodes, a plurality of first rules that identify a plurality of packet flows, respectively;
- and
- a second unit that sets, in the second node, a second rule that identifies the plurality of packet flows as a group, and
- wherein the plurality of packet flows are flows between the two first nodes via the second node, and
- when the first nodes and second nodes receive an unknown packet, the first and second nodes request the setting apparatus to set the corresponding first or second rule, and
- first nodes process a received packet based on the set first rule, and the second node processes a received packet belonging to one of the plurality of packet flows based on the set second rule.
A communication terminal identifying packet flows based on predetermined rules and processing packets belonging to identified packet flows, the communication terminal comprising:
- a first unit that receives from a setting apparatus a plurality of first rules that identify a plurality of packet flows, respectively;
- and
- a second unit that transmits in accordance with the first rules a packet to a second node, in which a second rule that identifies the plurality of packet flows as a group is set from the setting apparatus,
- wherein:
- the communication terminal comprises one of two nodes receiving the plurality of first rules,
- the second node is arranged between the two nodes receiving the plurality of first rules, and
- the plurality of packet flows are flows between the two nodes via the second node, and
- when the one node and the second node receive an unknown packet, the one and second nodes request the setting apparatus to set the corresponding first or second rule, and
- the one node processes a received packet based on the set first rule, and the second node processes a received packet belonging to one of the plurality of packet flows based on the set second rule.
