摘要： A method and system for managing network services such as subscription services from a cable modem in a data-over-cable system. The cable modem receives an initialization message on a cable television connection indicating what services are available on a data network. The cable modem uses a connection to a public switched telephone network in the data-over-cable system to send requests to and receive responses from the data network. A telephony remote access concentrator on the public switched telephone network provides an additional security mechanism by not allowing a cable modem to subscribe to unauthorized services. Using the public switched telephone network does not compromise the security of the cable television network. In addition, the public switched telephone network is used to provide administrative support to the cable television network on lower bandwidth connections by providing an administrative pathway outside of the higher bandwidth cable television connections.

摘要： Methods for providing restricted access for a network device such as a cable modem or customer premise equipment on a data-over-cable system. An unknown or new network device is assigned a restricted network address such as a restricted Internet Protocol address. The restricted network address allows the network device to access less than all of the available features on the data-over-cable system. A connection timer is started on the data-over-cable system for a restricted connection to the network device. The connection timer restricts access to the data-over-cable system over a timed interval. A restricted connection is created between the data-over-cable system and the network device including the temporary restricted network address and the connection timer, thereby providing restricted access to the data-over-cable system over a timed interval. The methods may allow a data-over-cable system to provide restricted connections to unknown or new network devices without a long delay, yet provide security to the data-over-cable system.

摘要： A method and system for virtual network administration with a data-over-cable system. A virtual networking tag and a network address (e.g., an Internet Protocol address) assigned by a network other than a data-over-cable system is used to provide a virtual network to one or more network devices, such as cable modems via a data-over-cable system. The virtual networking tag may also be used to request a desired service class (e.g., Class-of-Service, Quality-of-Service, Type-of-Service, Service Level Agreements, etc.), for a desired end-to-end networking service (e.g., Voice over Internet Protocol). The virtual networking tag can be mapped to a data-over-cable service class. The data-over-cable service class can be mapped into a transport service class for a transport network. The virtual networking tag is used to provide a desired end-to-end networking service from a network device on a first external network (e.g., an Ethernet Local Area Network), through the data-over-cable system, through a transport network (e.g., Asymmetric Digital Subscriber Line, Asynchronous Transfer Mode, Frame Relay, Integrated Services Digital Network, Synchronous Optical Network, Voice over Internet Protocol, etc.) and to a second external network (e.g., another Ethernet Local Area Network). The method and system are used to provide a variety of networking services via and through a data-over-cable system.

摘要： A method and system are provided to allow a cable modem to resolve addresses for a selected network host interface on a cable television network to connect the cable modem to a data network (e.g., the Internet). The cable modem is used in a data-over-cable system with telephony return. The cable modem is connected to a cable television network over a downstream cable data channel and connected to a public switched telephone network over a serial telephone line. The method provides a way for the cable modem to resolve an address for a selected network host interface (e.g., Internet Protocol host) available on the cable television system via the upstream channel connected to public switched telephone network. The method includes using existing Dynamic Host Configuration Protocol messages and message fields to discover network host interfaces available on the cable television system even though the cable modem only has downstream connection from the cable television network. The method and system can also be used on a data-over-cable system without telephony return.

摘要： System and method for providing a multi-frequency upstream transmission channel to a network device. When a headend network entity generates an upstream channel descriptor message, the descriptor message includes at least two upstream frequencies available for upstream transmission, and a frequency hopping descriptor with a frequency-hopping pattern associated with the available frequencies for determining an upstream frequency for upstream transmission. The headend provides a timing reference for determining upstream transmission periods on the frequencies available on the network device. When the headend receives upstream transmission on one of the available upstream frequencies, the headend network entity determines frequency distortions. If the distortions exceed a threshold level, the headend may send a new upstream channel descriptor message that excludes the upstream frequency associated with the high frequency distortions, add a new upstream frequency, or defines a new frequency-hopping pattern.

摘要： A routing Cable Modem Termination System (CMTS) configured to enable Point-to-Point Protocol over Ethernet (PPPoE). The routing CMTS may bridge Ethernet frames related to a PPPoE connection from a first network to a second network. Bridging Ethernet frames allows terminals in different networks to establish a PPPoE connection. A routing CMTS may also collect state information regarding PPPoE connections. The routing CMTS may use the state information to only bridge Ethernet frames related to valid PPPoE connections. It may act as a firewall to prevent spoofing attacks.

摘要： A system and methods for traffic gating in a computer network comprising a plurality of subnets are developed. One of the methods implemented in a data-over-cable system includes, responsive to receiving a first address resolution request message on a cable modem from a first host to a second host, generating a second address resolution request message on the cable modem and sending it to the second host. If the second host does not respond with an address resolution protocol reply message to the second request message, the cable modem determines a network subnet associated with the first host. Based on the network subnet, the cable modem determines a network address of a network element arranged to provide routing services to hosts on the subnet associated with the first host. Next, the cable modem generates an address resolution reply message including the network address of the network element and sends it to the first host.

摘要： A method and system for changing type-of-service with an associated quality-of-service in a data-over-cable system is provided. The method and system allow a cable modem or a cable modem termination system to dynamically override the statically assigned type-of-service supplied to the cable modem in a Dynamic Host Configuration Protocol (“DHCP”) initialization sequence. A selection input can request a second type-of-service that may or may not be supported by the cable modem on the cable modem termination system. If the requested second type-of-service with an associated second quality-of-service is permitted on the cable modem, the cable modem termination system dynamically changes the first type-of-service to the requested second type-of-service. Allowing a cable modem and cable modem termination system to change the statically assigned type-of-service to a second type-of-service allows the user greater flexibility for configuration cable modems in a data-over-cable system.

摘要： Methods and system for service level agreement enforcement on a data-over-cable system. One or more service level agreements are created including one or more class-of-service or quality-of-service parameters. A pool of Internet Protocol addresses is allocated for the one or more service level agreements. Configuration files including service level agreement parameters are used to initialize cable modems or customer premise equipment. When a cable modem or customer premise equipment requests use of a service level agreement, an Internet Protocol address from the pool of Internet Addresses associated with a desired service level agreement is assigned. The service level agreements are enforced using the Internet Protocol address from a cable modem termination system including an integral switch cable access router and a bandwidth manager. The cable modem termination system with integral components are duplicated to provide a “hot back” up in case of failure and increase reliability for using service level agreements. The cable access router enforces maximum rate limits for service level agreements. The switch switches data streams from external networks from the data-over-cable system. The bandwidth manager provides class-of-service or quality-of-service services with policy management and detects network trends, measures network response time and generates reports. The bandwidth manager also monitors, regulates and shapes traffic based on service level agreement requests at a data-link layer level. The methods and system allow service level agreements to be used on a data-over-cable system without adversely affecting performance or throughput on the data-over-cable system. The methods and system may also help provide service level agreements in a data-over-cable system in a more reliable manner.
