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.

A cable distribution system includes a head end connected to a plurality of customer devices through a transmission network that includes a remote fiber node that converts digital data to analog data suitable for the plurality of customer devices, where the head end includes at least one server each of which includes a respective processor.

Availability and redundancy for vCores

Systems and methods for analyzing network parameters in a data communications network so as to maintain a desired Quality of Experience (QoE) of at least one subscriber.

Methods, systems, and computer readable media can be operable to facilitate the provisioning of a device using an embedded cable modem media access control (MAC) address. An optical network unit (ONU) may include an embedded cable modem, wherein the embedded cable modem has a dedicated MAC address. Provisioning servers may provide identical configuration files to a virtual cable modem at an optical line termination (OLT) and the embedded cable modem at the ONU. The embedded cable modem MAC address, along with an associated Internet protocol (IP) stack, enables traditional DOCSIS cable modem provisioning and management over a passive optical network.

A device, deployed at the edge of a provider network, includes logic to receive traffic from one or more customer edge devices, and to encapsulate the customer traffic into a Layer 2 tunnel of an IP frame. The IP frame in further included within an Ethernet frame, and quality of service priority bits are promoted from the customer traffic into both the IP frame and the Ethernet frame.

Extended layer two tunneling protocol applications and architectures

Systems and methods can operate to improve the communication bandwidth in communication systems. Communication systems can use new forward error correction (FEC) algorithms to increase communication bandwidth. New FEC algorithms can also enable the use of other modulation formats to further improve communication bandwidth. Communication devices that can select from a plurality of FEC algorithms and modulation formats can maintain backward compatibility with the deployed FEC algorithms and modulation formats implemented in legacy communication devices while realizing increased communication bandwidth.

Forward error correction for communications systems

A translation agent adapts DOCSIS information, primarily QoS information, for transmission over a PON. The agent places into an IP address field of a DHCP message the MAC address of an ONU associated with a CPE device attempting to register with a CMTS. The translation agent intercepts DHCP reply messages from the DHCP server using the MAC address of the ONU. The translation agent extracts information, including an IP address of the client CPE assigned by the DHCP server. The agent downloads a configuration file for the CPE device using the configuration filename and configuration file server contained in a DHCP reply message. Information contained in the configuration file is converted from content in a format used by DOCSIS, to content in a format used by PON devices. The translated content includes QoS parameters, functions related to which are controlled at the ONU by an OLT coupled to the CMTS.

A network includes a provider edge device with logic to encapsulate Ethernet frames received from customer equipment into Data Over Cable Service Interface Specification (DOCSIS) frames using Layer Two Tunneling Protocol. The provider edge device further includes logic to implement a virtual switch instance (VSI).
