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.
