DYNAMIC NETWORK CONFIGURATION FOR UNIDIRECTIONAL ADAPTOR USING AGENT IN COMMUNICATION WITH RESOURCE SERVER THROUGH CONFIGURED FEEDBACK PATH

摘要

PROBLEM TO BE SOLVED: To receive data through a downstream broadcast channel while transmitting data to a computer network through an upper-stream telephone line. SOLUTION: A terminal server 144 obtains an IP address from a telephone address server 146 and assigns the address to a telephone MODEM stack 126. A cable MODEM stack 122 sends a request for session initialization to a cable MODEM driver, the request is processed by a PPRA 124, and the IP address of a telephone MODEM is inserted in a packet. The IP packet destination address is set to a cable address server 114. The server receives a packet through an upper-stream telephone line and replies the IP address and relay agent address configuration information. The telephone MODEM gives it to the cable MODEM stack through the PPRA. The cable MODEM is initialized and receives Internet data through a unidirectional RF channel.
