Patent ID: 8146133

Claim:
A peer-to-peer (P2P) traffic management system that manages P2P traffic on a network through which encrypted P2P traffic is exchanged, the P2P traffic management system comprising: one or more hardware processors; P2P software flow agents, to monitor executed application programs to extract a P2P application program, to add application identifiers to encrypted packets generated by the application program according to a policy set for the extracted P2P application program, and transmits to transmit the encrypted packets; P2P software security gateways to monitor the encrypted packets from the P2P software flow agents, to extract the encrypted packets including the application identifiers, to use the extracted application identifiers to inquire and acquire a related policy, and to control the encrypted packets according to the acquired policy; and a hardware live policy update server to detect a new policy input from a domain manager and to provide the detected new policy and its operation rules to the P2P software security gateways, wherein the hardware live policy update server configured to transmit the detected new policy and the operation rules to at least one P2P software security gateway on the network, or the hardware live policy update server configured to transmit the detected new policy and the operation rules to one P2P software security gateway and the one P2P software security gateway is configured to receive the detected new policy and to transmit the detected new policy and the operation rules to other P2P software security gateways on the network; and wherein the P2P traffic management system is configured to selectively recognize and control the P2P application program that generates the encrypted P2P packets where an inspection on a header or payload of the packets is impossible, to transmit and receive the encrypted packets.
