A method for using broadband network resources includes providing simultaneous access to an asynchronous transfer mode switched virtual circuit for a plurality of sessions. The access for each session is provided based on an internet protocol session request being received at a service gateway for the sessions. The method also includes tearing down the asynchronous transfer mode switched virtual circuit when all of the sessions are terminated.

Virtual private network over asynchronous transfer mode

A communications network and method enable broadband service subscribers to dynamically select broadband service destinations they wish to access from subscriber customer premises equipment. The communications network is an ATM network including a plurality of ATM switches. The network also includes at least one directory server connected to the ATM network, at least one fiber terminating device connected to the at least one directory server, and at least one broadband destination connected to the ATM network. Furthermore, the subscribers' customer premise equipment is connected to the at least one fiber terminating device. The method includes receiving a session request, which identifies a destination, in the at least one service gateway, wherein the session request is transmitted over a broadband connection using an Internet protocol. Next, using the at least one service gateway, an ATM network address of the destination from the at least one directory server is retrieved. Then an SVC is launched over the ATM network from the at least one service gateway to connect the subscriber to the ATM network address. Finally, the subsequent packets are forwarded to the destination over the ATM SVC connection.
