Patent number: 7296283Abstract: Apparatus for a cable television subscriber to log onto a computer network with a modem over an upstream path using a USERID and password. The network validates the subscriber USERID and subscriber password with a stored database of valid USERIDs and associated passwords. After the USERID and password are validated, the modem then provides it electronic serial number to the network for validation against a stored database of authorized serial numbers. Upon additional validation of the modem's serial number, the subscriber is authorized to use the network.Type: GrantFiled: August 14, 2001Date of Patent: November 13, 2007Assignee: Scientific Atlanta, Inc.Inventors: Scott E.

Patent number: 7099308Abstract: 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).Type: GrantFiled: June 9, 2003Date of Patent: August 29, 2006Assignee: Scientific-Atlantic, Inc.Inventors: Todd A. Merrill, Mark E. Schutte, Scott E. Hrastar, Roy A. Bowcutt

Publication number: 20030198215Abstract: 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 down link connecting the personal computers to the Internet is the cables provided by the CATV system; the up link is a telephone connection to the head end. A router is connected to the down link by means of an RF modem, to the up link by means of an analog modem, and to a LAN, which is connected to the PCs. The router routes IP packets for the hosts that are received on the CATV cable to the head end via the LAN; it routes IP packets from the hosts that are destined for the Internet to the head end via the telephone line. The asymmetrical network conserves IP addresses and addresses on the CATV cable by dynamically allocating the IP addresses for an RF modem's hosts and an address on the CATV cable for the RF modem in response to a request made by the RF modem via the telephone line.Type: ApplicationFiled: June 9, 2003Publication date: October 23, 2003Inventors: Todd A.

Patent number: 6308328Abstract: Apparatus for recording and collecting usage and other statistical data from components of a cable data network comprises a network manager for maintaining and collecting the statistics. Internet protocol addresses are associated with components of the network. The component maintains a software agent that manages a statistics database. Responsive to a manager request generated at a service provider defined time interval, the component software agent provides the usage statistics to the network manager in real-time during an Internet session with a host. When the host to Internet or other data connection is torn down due to failure, disconnect or inactivity time-out, remaining usage statistics data is collected and the session duration updated with the time of tear down.Type: GrantFiled: April 10, 1997Date of Patent: October 23, 2001Assignee: Scientific-Atlanta, Inc.Inventors: Roy A.

Patent number: 6282208Abstract: Method and apparatus for monitoring data traffic through a cable data network in order to guarantee a minimum and maximum bandwidth and burst length. Traffic statistics are kept as credits that are only updated as needed. Each cable modem in the network is assigned a limit on the maximum amount of traffic that it may transmit and receive depending on the service level that the subscriber has purchased. When that limit is exceeded, traffic for that modem will no longer allowed to pass through the system.Type: GrantFiled: December 17, 1997Date of Patent: August 28, 2001Assignee: Scientific-Atlanta, Inc.Inventors: Roy A.

Patent number: 5450416Abstract: An improved apparatus and method for isolating faults in a complex communications network such as a collision-detection network. A wrap plug connected to a communications adapter of a computer system simulates multiple functions of the network environment, rather than a single, hardwired function. A method performs a comprehensive yet convenient diagnostic test of multiple functions of the adapter while a terminal is disconnected from the network.Type: GrantFiled: August 25, 1992Date of Patent: September 12, 1995Assignee: International Business Machines CorporationInventors: Roy A.
