Virtual splits using power domain NOMA

Virtual element management systems, methods and computer readable media are disclosed. A virtual element management system may include an orchestration layer, a control layer, and one or more adapters. The orchestration layer may receive a request formatted in accordance with a device-independent language from customer premises equipment via a first interface and may communicate the request to an appropriate adapter via the control layer. The adapter may translate the request to a device-specific request formatted in accordance with a device-specific language and may communicate the request to a network device via a second interface.

Virtual element management system

A network taxonomy indicating relative locations of network access device within an access network is determined using timing data, performance data such as equalization coefficient data, and/or various other types of data. The timing data may indicate a travel time for a pair of network messages (e.g., network packets) between two network nodes such as two network access devices within the access network. A distance between the two network nodes may then be determined using this time of travel and a propagation velocity of signals transmitted through a transmission media via which the network nodes are connected.

Determining a network taxonomy using network transmission data

Aggregate functionality associated with multiple network communication layers may be decomposed and respective functionality associated with different network communication layers may be implemented on different devices. One or more aspects of respective functionality associated with a particular network communication layer may be virtualized based on the decomposition of the aggregate functionality. Virtual customer networks may be established for providing network-based services to a subscriber of an access network.

Virtual customer networks and decomposition and virtualization of network communication layer functionality

A multi-modal digital terminal adapter (DTA), and associated methods and computer-readable media, are disclosed for determining a current mode of operation of the DTA, selectively activating and/or deactivating one or more receiving modules based at least in part on the current mode of operation, and routing an incoming signal to one or more receiving modules based at least in part on one or more characteristics of the signal to initiate processing of the signal in accordance with the current mode of operation for the multi-modal DTA.

Certain embodiments herein relate to a hybrid cable that includes a center conductor for distributing electrical signals and one or more optical fibers adjacent to the center conductor for distributing light signals in a service provider network. According to one configuration, materials found in a coaxial cable may be included in the hybrid cable, such as a dielectric material, one or more protective shields, and an outer protective core. Such a hybrid cable may be utilized to replace drop cables in a service provider network, which may connect an access point, such as a tap, to a customer location. Certain embodiments herein may also relate to making and installing the hybrid cable.

Integrating optical fiber with coaxial cable

Systems and methods for routing broadband communications are provided. Downstream data to be communicated from a cable service provider head end system to a customer device may be received by a provider edge routing device. The downstream data may be mapped by the provider edge routing device to a physical address associated with the customer device, and the downstream data may be output by the provider edge routing device for communication to the customer device. A provider edge device separate from the provider edge routing device may receive the output downstream data. Based at least in part upon the physical address, the provider edge device may determine a port for outputting the downstream data, and the provider edge device may output the downstream data on the determined port.

Systems and methods for routing broadband communications

Providing a dynamic bandwidth increase using at least one token bucket is disclosed. At least one token bucket is pre-loaded to capacity using PCMM commands to dynamically implement speed increases in the network. By pre-loading the at least one token bucket to capacity, the rate cap assigned to the customer is overridden. When the token bucket is exhausted the customer continues at their provisioned rate cap. Only a configuration file has to be changed to implement the temporary bandwidth increase. The token buckets may be implemented on a per service flow basis. Further, a plurality of token buckets may be provided, wherein a first token bucket is configured to control a total burst size and a second token bucket is configured to control an individual flow burst rate up until the first token bucket is depleted.

Preloading token buckets for dynamically implementing speed increases

Systems and methods for buffering or delaying data packets to facilitate optimized distribution of content associated with the data packets are disclosed. Data packets sent from content providers may be received by a service provider, where information associated with the data packets may be identified. The identified information may be used to associate the data packets with an intended destination for the data packets and identify a type of the data packets, such as a video data packet. Video data packets (and other data packets) may be buffered or delayed such that more time-critical data packets may be accelerated into one or more QAM channels carrying the content. The delayed data packets may be time-sliced into the one or more QAM channels, which may displace empty slots or gaps that may waste bandwidth associated with the QAM channels.

Systems and methods for managing network bandwidth via content buffering

Systems and methods for distributing content over various mediums in a service provider network are disclosed. Such mediums may include an optical fiber and a cable line having a bandwidth less than that associated with the optical fiber. In certain embodiments herein, content may be distributed over the cable line, or relatively low bandwidth medium, according to characteristics of the optical fiber, or relatively high bandwidth medium. In one embodiment, data packets may be scheduled using first in first out (FIFO) scheduling for distribution over the cable line using Orthogonal Frequency Division Multiplexing (OFDM). Using this approach, increased bandwidths may be achieved over cable lines. Additionally, certain embodiments herein are directed to maintaining a forward/reverse channel split, which may exist in a PON, over a cable line. Further, certain embodiments herein may relate to dynamic allocation of subcarriers in an OFDM signal in response to changes in quality of service.

Systems and methods for distributing content over multiple bandwidth mediums in a service provider network

A secure mechanism for third party hosted services to communicate with networks to allow dynamic quality of service to be provisioned for content of the third parties is disclosed. By authenticating the third party hosted services, the service provider is able to enter into business arrangements to share revenue with the third party content providers based on the premium service. A subscriber issues a request to a third party server. In response to issuing the request to the third party server, a dynamic quality of service request is received from the third party server. The dynamic quality of service request is validated and a session is provisioned between the client and the third party server implementing the requested dynamic quality of service.
