摘要： A method and system for managing addresses of network host interfaces in a data-over-cable system such as Internet Protocol interfaces. The method allows network host interfaces addresses to be removed from routing tables on network devices such as cable modems or customer premise equipment when their lease expires. This helps prevent the data-over-cable system from exhausting available network host interface addresses of the data-over-cable system. In addition, the method helps ensure that transactions are not conducted on a network host interface address in the data-over-cable system unless it has a valid lease in the one or more routing tables on network devices.

摘要： A method and system for providing management functionality with a cable modem with telephony return is provided. The cable modem with telephony return is used for providing management functionality such as maintenance and signaling via the lower bandwidth telephony return path, leaving more higher bandwidth cable television channels free for data transmission. Since routine management functions such as maintenance are completed on the cable television channels via the telephony return path, the overall costs of maintaining the higher bandwidth cable television channels are reduced. In addition, since routine management functions are carried out via the telephony return path, fewer overall maintenance functions need to be carried out on the higher bandwidth cable television channels, requiring less down time and generating more revenues for the cable television network providers.

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： 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.

摘要： A method and system for policy provisioning and access managing on a data-over-cable system. One method includes receiving a first message on a first network device such as a CMTS from a second network device and marking the first message with an identifier of a network access device. The method further includes intercepting the first message on a third network device prior to a first protocol network server such as a Dynamic Host Configuration Protocol (“DHCP”) server receives the first message. When the third network device intercepts the first message, the third network device determines the identity of the second network device. Based on the identity of the second network device and using the identifier of the network access device, the third network device manages an assignment of configuration parameters for the second network device.

摘要： The present invention relates to an improved mounting for stacking modem devices. Each mounting includes stacking feet and stacking slots that permit the mountings to be securely stacked on top of one another. Each mounting is configured to receive a modem device. Each mounting also includes connectors configured to interconnect with corresponding connectors of the modem device. For instance, each mounting and the modem have interconnecting power connections, RJ-45 connections, cable connections, and serial data connections. The modem devices can be slid into place for testing, initialization or installation without disassembling the stack. The present invention also provides configuring the mountings so the multiple modem devices can be connected back to back and communicating without a hybrid fiber/coax network connection.
