  • Publication number: 20060224717
    Abstract: In inter-peer communication between an application server for providing service such as Voice over IP or contents distribution and a client using the service, the client or the application server notifies a log management server of a communication log by a log information process. The log management server verifies consistency of the notified communication log by a log compare process requested by the client or the application server. Because the log information process and the log compare process are executed periodically during inter-peer communication, the client and the application server can detect inconsistency of the communication log instantaneously and notify each other of the consistency of the communication log.
