Abstract
A cable network includes a Data Over Cable Service Interface Specifications (DOCSIS) set-top gateway (DSG) server connected to an Internet Protocol (IP) network and a DSG client operating in a set-top device connected to a cable network. A DSG agent operates in a cable modem termination system (CMTS) coupled between the IP network and the cable network. The DSG agent receives data from the DSG server and sends the data to the DSG client over dynamically assigned DSG tunnels.
