Abstract: Systems and methods for steering data packets among a plurality of available network devices. A device connected to a wide area network through multiple network interfaces may dynamically select which network interface to use to transmit individual packets sent to, and received from, client devices over a local area network.

Abstract: 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.

Abstract: A bi-directional coupler assembly includes a first port for connecting to one of an input forward path RF signal line and an output forward path RF signal line. A second port connects to the other of the input forward path RF signal line and the output forward path RF signal line. A relay is connected between the ports and to at least one directional coupler. In a first state of the relay, an input forward path RF signal delivered from the input forward path RF signal line and through the first port is directed through the at least one directional coupler in a first direction. In a second state of the relay, an input forward path RF signal delivered from the input forward path RF signal line and through the second port is directed through the at least one directional coupler in said first direction.

Abstract: Particular embodiments provide an N+0 sharing scheme for networks. The N+0 sharing scheme includes no dedicated spare among a group of active elements. Each active element may provide service to a medium, which may be associated with a medium. When a failure to one of the active elements occurs, at least one of the working active elements takes the workload of the failed active element. The cost of N+0 sharing is a reduced per medium (e.g., service group) capacity during a failure. That is, some service groups may receive less bandwidth from the active element that is used in the sharing scheme to compensate for the failure. However, this may be preferable to service operators compared to the additional cost of including a spare for the group of active elements, or the complete loss of service that occurs when a failure occurs without a failure recovery scheme.

Abstract: 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.

Abstract: Particular embodiments identify customer premise equipment (CPE) in a subscriber's premises that may potentially cause interference with other devices. For example, the interference may occur within an interfering spectrum where an interfering CPE transmits upstream in a frequency band that is the downstream frequency band for other customer premise equipment, such as legacy CPEs. Once the CPE is identified, when the CPE sends a request to initialize the CPE on the network, a cable modem termination service (CMTS) may adjust the target power level for a transmitter transmitting upstream content within the interfering frequency spectrum. For example, for those CPEs that transmit upstream using upstream channels within an interfering spectrum, such as within 54-85 MHz, the power level for these CPE may be reduced. Other CPEs that are not transmitting upstream in this interfering spectrum may not have their power reduced.

Abstract: Methods and apparatuses for adaptively multicasting information from a server to a multicast group are provided. A multicast transmission along one or more paths of the transmission is changed as network conditions warrant.

Abstract: 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.
