Abstract:
A network access server, comprising:a packet network interface, for coupling to and communication of data via a packet switched data network; a telephone network interface in communication with the packet network interface, for connection to and communication of the data through a switched telephone network; a programmable controller coupled to the network interfaces for controlling data communications through the network interfaces; a telephone network interface in communication with the packet network interface, for a memory coupled to the programmable controller for storing program code executable by the programmable controller; and executable code stored in the memory, wherein execution of the code by the programmable controller causes the network access server to: receive a name translation query, via the packet network interface, for a name associated with a destination computer system accessible from the network access server via the switched telephone network; establish a dial-out link from the telephone network interface through the switched telephone network to the destination computer system associated with the name and initiate data communication via the dial-out link with the destination computer system; temporarily assign a packet network address to the destination computer system from among a pool of addresses available to the network access server; and send a response to the query via the packet network interface, the response containing the temporarily assigned packet address as a translation of the name.
