Communication control system
First Claim
1. A communication control system, comprising:
- an authentication server that authenticates a terminal which requests subscription to a network, sends communication priority information to the terminal whose subscription is permitted, and delivers communication regulation information based on the communication priority information to a router which accommodates the terminal;
a terminal that uses a packet, in which the communication priority information sent from the authentication server is marked, to perform communication after having subscription thereof permitted; and
a router that monitors the packet sent from the terminal, and imposes a communication regulation on the terminal according to the communication regulation information based on the communication priority information and delivered from the authentication server, wherein;
the terminal requests subscription to a predetermined group;
the authentication server determines the communication priority information on the basis of the degree of importance of the group, periodically creates as the communication regulation information a cease-communication eligible group ranking list according to the degree of importance of the group, and delivers the cease-communication eligible group ranking list to the routers;
the router monitors an amount of traffic represented by the packet in relation to each communication priority information so as to sense a congestion condition; and
when having sensed congestion, the router uses the cease-communication eligible group ranking list to request the terminal, which belongs to a group whose degree of importance is low, to cease communication.

Abstract
The present invention relates to a communication control system, and provides specifically a peer-to-peer (P2P) communication control system making it possible to effectively exploit P2P communication within an organizational network. The communication control system includes: an authentication server that authenticates a terminal which requests subscription to a network, sends communication priority information to the terminal whose subscription is permitted, and delivers communication regulation information based on the communication priority information to a router which accommodates the terminal; a terminal that uses a packet, to which the communication priority information sent from the authentication server is appended, to perform communication after having subscription thereof permitted; and a router that monitors the packet sent from the terminal, and imposes a communication regulation on the terminal according to the communication regulation information based on the communication priority information and delivered from the authentication server.
