A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.

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).

A transmitting and/or receiving system for cable networks.

Implementations described and claimed herein provide systems and methods for intelligent node type selection in a telecommunications network. In one implementation, a customer set is obtained for a communications node in the telecommunications network. The customer set includes an existing customer set and a new customer set. A set of customer events is generated for a node type of the communications node using a simulator. The set of customer events is generated by simulating the customer set over time through a discrete event simulation. An impact of the customer events is modeled for the node type of the communications node. The node type is identified from a plurality of node types for a telecommunications build based on the impact of the customer events for the node type.

Embodiments may be disclosed herein that provide systems, devices, and methods of operating a Multimedia over Coax (MoCA) network. One such embodiment is a method comprising: designating a selected MoCA device as a network controller; and logically partitioning, into virtual MoCA networks, a predetermined bandwidth reserved for the MoCA network by sending, from the network controller one or more beacons containing virtual network information.

The present disclosure generally pertains to systems and methods for communicating data. In one exemplary embodiment, a system has a high-speed channel, such as an optical fiber, between a network facility, such as a central office (CO), and a first intermediate point between the network facility and a plurality of customer premises (CP). Digital communication links, such as DSL links, are used to carry data between the first intermediate point, such as a feeder distribution interface (FDI), and a second intermediate point, such as the Distribution Point (DP). Non-shared links may then carry the data from the second intermediate point to the CPs. The links between the two intermediate points are bonded to create a high-speed, shared data channel that permits peak data rates much greater than what would be achievable without bonding. In some embodiments, multicast data flows may be prioritized and transmitted across a set of connections to each of the intermediate points. In addition, it is possible to power components at the intermediate points from one or more of the CPs.

An optical line terminal (OLT) detects content distribution conditions in terminals, and performs control for performing switching to distribution to each terminal using an individual virtual local area network (VLAN) or distribution to a plurality of terminals by broadcasting using a broadcasting VLAN, in accordance with the detected content distribution conditions. The OLT detects that the number of viewers of a predetermined channel exceeds a predetermined threshold value or is less than the predetermined threshold value, as the content distribution conditions. Further, the OLT performs switching to distribution using a broadcasting VLAN in a case where it is detected that the number of viewers of the predetermined channel exceeds the predetermined threshold value, and performs switching to distribution using an individual VLAN in a case where it is detected that the number of viewers of the predetermined channel is less than the predetermined threshold value.

An intermediate node obtains a lead packet of a plurality of packets in a session having a unique session identifier, modifies the lead packet to identify at least the intermediate node, and then forwards the lead packet toward the destination node though an intermediate node electronic output interface to the IP network. The intermediate node also receives, through an intermediate node electronic input interface in communication with the IP network, a backward message from a next node having a next node identifier. The backward message includes the next node identifier and the session identifier. The intermediate node forms an association between the next node identifier and the session identifier, stores the association in memory to maintain state information for the session, and obtains (e.g., receives) additional packets of the session. Substantially all of the additional packets in the session are forwarded toward the next node using the stored association.

The present disclosure includes systems and techniques relating to Point-to-Multipoint (P2MP) communication networks and G.hn networking standards used therewith. In some implementations, the system includes a domain master (DM) network device and one or more network devices. The DM network device is configured to receive control request messages from one or more network devices, establish a connection via a point-to-multipoint (P2MP) network coupling to the one or more network devices based on the received control request messages, and transmit control messages to one or more network devices via the connection. A network device is configured to receive the control messages from the DM network device, receive data from a backbone network coupled to the P2MP network coupling, and transmit the received data to a designated client device through the P2MP network coupling in accordance with a P2MP communication protocol using a resource allocation received in the control message.

An OLT (1) is formed by N optical transceivers (11), one PON control circuit (12), and one selection and distribution circuit (13). An optical transceiver selection control signal (SC) is transferred from the PON control circuit (12) to the selection and distribution circuit (13). The optical transceiver selection control signal (SC) indicates the timing of a discovery window, the timing of a grant, and a logical link identification number of a registered ONU assigned to the grant (a logical link identification number for a logical link with the registered ONU). The selection and distribution circuit (13) selects one optical transceiver (11-s (s is an integer falling within a range of 0 to N−1)) from the optical transceivers (11-0 to 11-N.sub.−1) based on the optical transceiver selection control signal (SC) from the PON control circuit (12).
