Abstract: An ideal tap may have a plurality of ports that include at least an input port configured for receiving downstream (DS) signals from and transmitting upstream (US) signals to nodes upstream from the tap within the coaxial network, and one or more other ports that comprise at least one of an output port configured for transmitting downstream (DS) signals to and receiving upstream (US) signals from nodes downstream from the tap within the coaxial network, and a drop port for receiving signal from and transmitting signals to customer premise equipment (CPE) in the coaxial network. The ideal tap may further include processing circuits for handling signals received and transmitted via the tap, with the one or more processing circuits being configured to meet particular predefined tap performance criteria, and to specifically apply, during handling of signals in the tap, frequency shifting based on one or more frequency spectrum shift conditions.

Abstract: Systems and methods are provided for utilizing low gain low noise signal amplification and ideal taps in coaxial networks. An ideal tap configured for use in coaxial networks may have a plurality of ports, one or more processing circuits configured for handling reception and transmission of signals communicated via the tap, and one or more echo cancellation circuits configured for providing echo cancellation during operations of the tap. The processing circuits are configured based on particular predefined tap performance criteria. The tap performance criteria may relate to one or more of port-to-port isolation, return loss, port-to-port gain, and up-tilt. The echo cancellation circuits may be configurable for providing the echo cancellation based on the tap performance criteria. The echo cancellation circuits may include an echo cancellation control circuit for controlling echo cancellation functions and/or operations. The echo cancellation circuits may include dedicated per-port echo cancellation circuits.

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 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.

Abstract: 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.
