Abstract

A router particularly providing a P2P traffic supporting router which discriminates and effectively controls P2P (Peer to Peer) traffic transmitted in a network. The router comprises a router part to execute a router function, a discrimination part to discriminate P2P traffic from input traffic, an assignment part to assign discrimination information to the P2P traffic discriminated in the traffic discrimination part, a notification part to create notification information to notify the discrimination information to other routers, and a controller to control the discriminated P2P traffic, wherein the router part outputs the notification information according to directions from the notification part and outputs P2P traffic containing the discrimination information according to directions from the controller.

Claims

1. A router comprising:

a router part to execute a router function;

a discrimination part to discriminate P2P traffic from input traffic;

an assignment part to assign discrimination information to the P2P traffic discriminated in the traffic discrimination part;

a notification part to create notification information to notify the discrimination information to other routers; and

a controller to control the discriminated P2P traffic, wherein

the router part outputs the notification information according to directions from the notification part and outputs P2P traffic containing the discrimination information according to directions from the controller.

2. A router according to claim 1, further comprising a table to store information on the discriminated P2P traffic, wherein

the discrimination information notification part creates the notification information corresponding to the stored information, with reference to the table.

5. A P2P traffic information sharing system structured by a network comprising a router according to claim 1.

6. A P2P traffic information sharing system according to claim 5, wherein

the router is arranged at an edge portion terminating a subscriber'"'"'s terminal of the network.

7. A router according to claim 1 wherein

the discrimination of the P2P traffic and the traffic control after discrimination are carried out for each packet of the P2P traffic.

9. A router according to claim 1, wherein

the controller reduces a transmission priority of the P2P traffic in the case of congestion.

3. A router comprising:

a router part to execute a router function;

a table to store discrimination information of P2P traffic notified from other router;

a determination part to determine that, when the discrimination information of the P2P traffic contained in input traffic and discrimination information stored in the table are compared and identical to each other, the traffic is P2P traffic; and

a controller to control the P2P traffic containing the discrimination information, wherein

said router part outputs P2P traffic containing the discrimination information according to directions from the controller.

4. A router according to claim 3, wherein

the table contains traffic control information for each of the P2P traffic in addition to the discrimination information, and

the controller controls the P2P traffic containing the discrimination information according to the traffic control information.

8. A router according to claim 3 wherein

the discrimination of the P2P traffic and the traffic control after discrimination are carried out for each packet of the P2P traffic.
