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.

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： 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 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： A method and system for provisioning network addresses in a data-over-cable system. Provisioning of network addresses allows multiple “always-on” network devices with multiple associated devices to be used on a data-over-cable system with a limited public network address pool. The “always-on” network devices provide services, such as, Voice over Internet Protocol (“VoIP”), that typically require instant access to data-over-cable system. Network devices such as “always-on” cable modems may allocated private network addresses (e.g., Internet Protocol addresses) on the data-over-cable system. The private network addresses are not addressable outside the data-over-cable system. Other network devices associated with the cable modems, such as customer premise equipment, may be allocated public network addresses (e.g., Internet Protocol Addresses) on the data-over-cable system. The public network addresses are addressable outside the data-over-cable system. The network address provisioning is accomplished by selecting a private network address marker and a public network address marker for selected network devices and using an extended Address Resolution Protocol table to determine a device type. The private network address marker or public network address marker is added to a Dynamic Host Configuration Protocol message field by a cable modem termination system. A Dynamic Host Configuration Protocol server uses the private or public address marker to allocate a private network address or a public network address on the data-over-cable system. The provisioning of network addresses allows two or more virtual networks to be created on the data-over-cable system, and may reduce a number of public network addresses required for a data-over-cable system.

摘要： A method and system for a mobile station to identify to a wireless network agent, an access point into a wireless network. The mobile station obtains an indication of an access point into the wireless network and inserts the indication into a mobile registration message. The access point identifier identifies an access point into the wireless network. Then, the mobile station sends the mobile registration message to the wireless network agent via the access point identified by the access point identifier. The wireless network agent receives the mobile registration message and provides the access point identifier to an authentication, authorization, and accounting (AAA) server. The AAA server uses the access point identifier to provide location-based services to the mobile station.

摘要： While one node (such as a wireless mobile node) facilitates a point-to-multipoint communication via a communications network (10), communication requests from other nodes in the multipoint audience are queued in a node queue (17). At some point (in a preferred approach, at the conclusion of the transmission by the one node), and typically for a predetermined amount of time, communication requests are further noted. These more recent indicia of a desire to communicate are then utilized to modify the node queue. Subsequent communications are then arranged, at least in part, based upon the modified node queue.

摘要： A system and method for integrating the call control signaling pathway with data network access components. A call control server agent is resident on a network device that provides a first interface from an access network to a packet-switched data network. The call control server agent receives data session initiation requests and passes the requests to the call control server agent. The call control server agent also performs proxy server functions and provides a source of information relating to data sessions directly to the access network.
