A Data Over Cable Interface Specification (DOCSIS) node includes a first DOCSIS port and a second DOCSIS port. The node also includes a plurality of radio frequency (RF) ports. A plurality of client devices can be coupled to the RF ports. A RF switching network is coupled between the first DOCSIS port and the second DOCSIS port, and the plurality of RF ports. One or more control circuits can switch the RF switching network between at least a first state and a second state. The switching of the RF switching network allows the one or more control circuits to identify which client devices are coupled to which RF ports of the node.

Systems and methods for dynamically updating bit loading profile assignments among a plurality of cable modems.

OFDM and OFDMA profile assignments for cable modems

A method receives error measurements from network elements. Groups of network elements are generated based on similarity of error measurements and a bitloading profile for each of the groups of network elements is generated based on the error measurements for each respective group. Each bitloading profile includes a modulation level determined to be sufficient for transporting content to respective groups of network elements. The method then assigns a set of bitloading profiles to each network element based on the groups of network elements and the bitloading profile generated for each of the groups. The bitloading profile for each of the groups of network elements and the assigned set of bitloading profiles are output to a network device. The network device uses the bitloading profiles to modulate content sent to respective customer premise equipment.

Management of bitloading profiles for network communications

A fiber optic node includes an electronics equipment enclosure. The electronics equipment enclosure includes a lid, a base, and at least one side wall defining an interior space of the electronics equipment enclosure. The fiber optic node further includes an optical receiver mounted within the interior space of the electronics equipment enclosure. The at least one side wall is coupled to the lid, the base, or both the lid and the base. The at least one side wall is formed of at least a semi-permeable fabric mesh. The semi-permeable fabric mesh includes a rigid mesh screen and a semi-permeable membrane coupled to the rigid mesh screen for convection of heat generated within the interior space by the optical receiver to outside the electronics equipment enclosure.

Methods and apparatuses for control admission to network resources are provided. Probationary service flows with a reduced priority are provisionally allowed to use network resources. As the network demonstrates its continued stability by the addition of the new probationary flows, each probationary flow can be re-assigned its original priority thereby promoting the probationary flow to a non-probationary status.

Stateless admission control

Methods, systems, and apparatuses can provide improved bandwidth and reduction in processing resources in a cable system using bonded upstream channels. Physical or environmental changes can occur in the HFC network effecting communication performance on one or more upstream channels. For optimal HFC network performance periodic measurements and adjustments are made reducing HFC network bandwidth and consume processing resources. This periodic maintenance is performed even if the communication service is not using the additional upstream bandwidth provided through upstream channel bonding. Demand-based bonded upstream channel allocation and de-allocation provides additional upstream bandwidth when required while optimizing HFC network performance and reducing processing resources through the reduction of periodic measurements and adjustments on the HFC network.

Method and apparatus for demand-based cable upstream channel assignment

With the introduction of orthogonal frequency division multiplexing (OFDM) technology in to communication channels in a cable network, cable modems that receive data downstream over subcarriers of the OFDM channel are grouped in to modulation tiers based on at least one metric. A profile is generated for each OFDM channel based on the measurements across cable modems and subcarriers related to the OFDM channel, including the metric values used to group the cable modems in to the modulation tiers. Included in an OFDM profile may be a scheme for allocating marginal cable modems in to the plurality of modulation tiers. The methods and systems for generating modulation and coding scheme profiles enable more efficient modulation by network elements.

Determining bitloading profiles based on sNR measurements

Particular embodiments provide systems and methods to reduce the average power consumption per subscriber. Particular embodiments select windows of time when network components are under-utilized by subscribers of the network. During periods of under-utilization of a network component, subscribers may be consolidated onto a smaller number of network components by increasing the service group size. The consolidation increases the service group size, which has the effect of lowering bandwidth per subscriber. However, the bandwidth use per subscriber may be lower during this time. The use of the smaller number of network components allows the energy for these components to be used more efficiently. When the subscriber network demands increase, the distribution system places the network components into an active power state and redistributes the subscribers to the newly-activated components. This decreases the service group size, such as back to the original size.

Power efficiency improvement in network equipment using service group consolidation

A cable television plant may include fiber nodes, cable modems, a management information base (MIB), and a cable modem termination system (CMTS). The CMTS may include logic to apply information from the MIB to determine the suitability of resources assigned to the fiber nodes from particular MAC domains for providing data communications.

Methods, systems, and apparatuses can provide for adaptive streaming using non-local information. Non-local information identifying usage statistics associated with a network service group can be collected and used to derive session parameters associated with each of a plurality of sessions within the network service group. The non-local information can also be updated and the updated non-local information can be used to dynamically adjust the session parameters.

Adaptive streaming using non-local information

Various methods, systems, and apparatuses can be used to consolidate unicast video streams into multicast video streams. In some implementations, a skewing window associated with multiple unicast video streams for a video can be identified using a maximum skewing rate and a program duration, and a multicast stream for the video can be generated based on the skewing window. The unicast video streams can then be skewed and merged with the multicast stream.

Consolidation of time-compressible time-offset media streams

Methods, systems, and computer readable media can be operable to detect possible fraudulent use of a customer premise equipment device. Information identifying a device connected to a customer premise equipment device can be retrieved and compared to historical information identifying one or more devices previously connected to the customer premise equipment device. The customer premise equipment device can be classified as a device suspected of fraudulent use when the current information identifying a device connected to the customer premise equipment device is different than the historical information identifying the one or more devices previously connected to the customer premise equipment device.

Customer premise equipment fraud detection

A name that means something to a human can be used to provision multiple channels, multiple times after a one-time association of an binary integer mask bit pattern with the name, or mnemonic. Typically, the one performing the one-time association of the mask pattern with the mnemonic will choose a name that reflects the channel attributes represented by the mask pattern. Thus, rather than remembering a bit pattern for a single attribute, or even the more difficult task of remembering the pattern for multiple attributes, and having to make sure a '1' is placed in a correct bit position among many '0's when entering bit patterns, the one provisioning only enters a mnemonic that textually refers to the attribute, or attributes, to be provisioned for a given channel.
