Approaches for a virtualized Cable Modem Termination System (CMTS) for providing high speed data services to a remote physical device (RPD). The virtualized Cable Modem Termination System (CMTS) comprises a core routing engine (CRE) for performing packet switching and routing and one or more physical or virtual compute servers (CS) that each perform CMTS functions for the one or more remote physical devices (RPDs). Each physical or virtual compute server (CS) connects to the core routing engine (CRE) with a Link Aggregation Group (LAG) of two or more Ethernet links.

Premises apparatus and methods for providing aggregated high-bandwidth, low-latency data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.

A method of using customer premises cable modem equipment to generate a signal that can be used for leakage detection. Various signal types are described which are usable for the purposes of leakage detection.

A particular overall architecture for transmission over a bonded channel system consisting of two interconnected MoCA (Multimedia over Coax Alliance) 2.0 SoCs (Systems on a Chip) and a method and apparatus for the case of a “bonded” channel network. With a bonded channel network, the data is divided into two segments, the first of which is transported over a primary channel and the second of which is transported over a secondary channel.

A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).

An optimizing agent of a network device that does not support low latency DOCSIS can identify traffic or packets associated with a client resource for an optimization service flow. For example, the optimizing agent can receive a priority notification associated with a client resource from a low latency controller that is indicative of a low latency requirement associated with the client resource. The optimizing agent identifies the traffic for the optimized service flow based on the priority notification. The identifying can require modifying one or more parameters of an existing service flow, creating a new service flow, or selecting an existing service flow with low latency. The identified traffic can be routed to the optimized service flow to achieve low latency or high QoS.

In one embodiment, a method receives a first time from a network device. The first time is derived from a first timing source in a first domain. The method receives a second time in a second domain from a second timing source. A difference time value is calculated between the first time and the second time. The method then sends the difference time value to the network device where the network device uses the difference time value to send a delay value to other computing devices to synchronize timing of the other computing devices in the second domain. The other computing devices are configured to synchronize the respective time using the delay value with mobile network devices to allow timing synchronization between the mobile network devices.

A system and method for facilitating and provisioning customer broadband transport service between a digital communication port employing digital communications and at least one communications provider, including communicating with a provisioning server to establish service and to coordinate service offerings of one or more communication providers.

In one embodiment, a method receives a downstream signal and an upstream signal in a same frequency band. The downstream signal and the upstream signal are separated into a first path and a second path. The downstream signal using the first path and the upstream signal using the second path are amplified in an analog domain. The method isolates the downstream signal and the upstream signal from one another and sends the downstream signal downstream to a subscriber device and sends the upstream signal towards a full duplex node.

Systems and methods for retaining synchronization between a CMTS core and an RPD when the RPD loses synchronization to a timing grandmaster, where both the core and the RPD are configured for individual synchronization in a slave configuration to the timing grandmaster, by operating the core as a boundary clock that sends timing information to the RPD.
