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： A method for network address maintenance in a data-over-cable system. The method includes receiving a message containing a first network address, such as an Internet Protocol address, to be stored in a network address table, such as an Address Resolution Protocol table. If the first network address equates to a second network address stored in the network address table, one or more network addresses associated with the second network address are deleted from the network address table. A third network address is then stored in the network address table. The method provides for the removal of stale network addresses, freeing memory space and increasing security in the data-over-cable system.

摘要： A method and system for quality-of-service in a data-over-cable system is provided. A cable modem in a data-over-cable system makes a connection request to a cable modem termination system with a requested quality-of-service. The requested quality-of-service includes class-of-service, quality-of-service and other related parameters. The connection request is sent from a cable modem or a cable modem termination system to a Quality-of-Service (“QoS”) server. The OoS server determines if the cable modem termination system has enough bandwidth to make the connection to the cable modem with the requested quality-of-service. If the cable modem termination system has enough bandwidth, a quality-of-service identifier is to returned to the cable modem termination system. The cable modem termination system uses the quality-of-service identifier to make a connection to the cable modem with the requested QoS to the cable modem. The QoS server reduces the computational burden and complexity of software on the cable modem termination system. The QoS server is flexible and adaptable to new QoS parameters and provides a standard way to balance QoS requests among multiple cable modem termination systems.

摘要： A method and system for dynamic service registration, activation and deactivation on a data-over-cable system. A first network device, such as a cable modem with associated service devices (e.g., Voice over Internet Protocol telephones) sends a first message to another network device, such as a cable modem termination system. The first message includes multiple service parameters for a desired service requested by a service device associated with the first network device. The multiple service parameters are extracted from the first message. A service session profile is created for the desired service. The service session profile includes one or more of the extracted service parameters required by the desired service. The service session profile is used by a service server associated with the cable modem termination system to provide a desired service. The service session profile is associated with a deferred inactive service identifier for the cable modem. The deferred inactive service identifier is returned to the cable modem in a second message. The deferred inactive service identifier is used at a later time by a service device associated with the cable modem to activate the desired service and to generate a service event on a service server. The service event may include an authentication, authorization, accounting or other event. A deferred service can be activated and deactivated used even after a network device, such as a cable modem, has already established a session with another network device, such as a cable modem termination system, on a data-over-cable system.

摘要： The present invention provides a method for testing and diagnosing a cable modem termination system, using a hand-held computing device. The hand-held computing device establishes a connection with the cable modem termination system through a wireless infrared and radio frequency connection, a serial, or a local area network connection. After the connection is established, a set of commands residing in the hand-held device are transmitted to configure the cable modem termination system. The cable modem termination system sends back a response that is displayed on a command screen of the hand-held device to identify status and error messages. A cable modem termination system operator can send a set of configuration instructions to the cable modem termination system by utilizing stored sets of configuration instructions. Using the hand-held device allows easy accessibility in remote locations with limited space for diagnostics and equipment.

摘要： A method and system for network address maintenance in a data-over-cable system. The method includes determining whether a network device, such as a cable modem, registers in a timely manner. When updating network address tables, such as Address Resolution Protocol tables, a time value is associated with an address, such as an Internet Protocol (“IP”) address, of a network device. If a time between two registration events exceeds this time value, the network address is deleted from the network address table. The deletion of the network address ensures that the device is isolated from the network. The method and system provide for the rapid removal of stale network addresses, freeing valuable memory space, and increasing security in a data-over-cable system.

摘要： A method and system for quality-of-service in a data-over-cable system using configuration protocol messaging is provided. The method and system include determining whether a cable modem termination system has enough available bandwidth to provide a quality-of-service connection requested by a cable modem from a quality-of-service server. The quality-of-service server uses Dynamic Host Configuration Protocol (“DHCP”) messaging to send and receive quality-of-service identifiers indicating that the cable modem termination system has enough available bandwidth to provide a quality-of-service connection requested by a cable modem. The cable modem termination system creates a quality-of-service connection to a cable modem based on the quality-of-service identifiers returned from the quality-of-service server. The quality-of-service server using DHCP messaging provides a standard and efficient process to reserve bandwidth for quality-of-service connections in a data-over-cable system. The quality-of-service server is also used to distribute quality-of-service connection requests from cable modems among multiple cable modem termination system in a data-over-cable system.

摘要： A switching system for allowing any one conferee on a video conference to assume the role of manually manipulating the video picture that will be seen by all conferees (chair view). In addition, each individual conferee is allowed to determine their own video picture content or to select the chair view. Further, anyone of conferees can assume the role of determining the chair view. In addition, for the video classroom, a chair view video picture is composed such that the picture displays the visual aid with an insert for an instructor and an insert for a student asking a question. Further, the instructor selects by using a button or mouse which student is to be displayed in the student insert, and the video picture automatically displays that student. In another embodiment of the system, the students request permission to ask a question by actuation of a switch on their telephone set, and the names of students asking questions are displayed on a computer display screen. The instructor then can select the student by manipulating the cursor on the computer display to select the desired student.

摘要： A method and system for load balancing in a network system such as a data-over-cable system. One method includes receiving a first message on a first network device such as a cable modem termination system (“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 such as a provisioning/access manager prior to any first protocol server such a Dynamic Host Configuration Protocol server receives the first message. When the third network device intercepts the first message, the third network device determines capabilities of the second network device and applies a set of rules to load balance any requests between a plurality of channel pairs. Each charmel pair is associated with at least one capability of a network device and also has a load factor parameter and a threshold value defining a capacity of a channel pair. The third network device assigns the second network device to a predetermined channel pair based on the capabilities of the second network device, a load factor of the channel pair and a capacity of the channel pair.
