摘要
According to the invention, each user connected to a termination (CM) of a Customer Premises Network (CPN) belonging to an ATM Virtual Private Network (AVPN) before transmitting his data with a given transmission bandwidth, sends a request to the access node through which he is connected to the public network.The user can start the data transmission only after having received confirmation of the acceptance of his bandwidth request by all the elements of the network involved in the connection.According to the invention all the functions for sending requests and signals to the transmission bandwidth allocations are performed at ATM level using particular ATM cells called Fast Resource Management cells (FRM).Always according to the invention the ATM-N node examines the content of a particular field of all the ATM cells and after identification of the same as Resource Management (RM) cells addresses the same to an output link (LINK-OUT) to which a Fast Resource Management server (FRMU) is connected.
