ABSTRACT:
An asymmetrical network is disclosed for coupling customer-premises Internet hosts such as personal computers to the Internet. The head end of a CATV system has a high-bandwidth connection to the Internet. The CATV system supports a plurality of concurrent channels to which an RF modem is capable of tuning. The RE modem is capable of receiving information from the head end that specifies the channel to which the RF modem should tune. Once tuned to the specified channel, the RF modem is capable of utilizing the CATV system for carrying high-speed data traffic. The high-speed data traffic can support Internet access using the Internet Protocol (IP).
