20080304490 | Systems and computer program products for header suppression in a network that guarantees in order delivery of packets - A method and computer program product for providing RTP suppression across a DOCSIS network. An index number and a set of rules are sent to a receiver. The index number indicates the type of header suppression technique (i.e., RTP header suppression) to be performed, and the set of rules define how to recreate the RTP packets on the receiving end. At least one complete RTP packet is transmitted upstream for enabling a receiver to learn the RTP header. Subsequent RTP packets are transmitted upstream for reconstruction at the receiving end. The subsequent RTP packets are comprised of delta values representing fields that dynamically change from packet to packet in an RTP header. | 12-11-2008 |
20090327845 | System and Method For Mitigating Burst Noise In A Communications System - A system, method and computer program product is provided for mitigating the effects of burst noise on packets transmitted in a communications system. A transmitting device applies an outer code, which may include, for example, a block code, an exclusive OR (XOR) code, or a repetition code, to one or more packets prior to adaptation of the packets for transmission over the physical (PHY) layer of the communications system, wherein the PHY layer adaptation may include FEC encoding of individual packets. The outer coded packets are then separately transmitted over a channel of the communications system. A receiving device receives the outer coded packets, performs PHY level demodulation and optional FEC decoding of the packets, and then applies outer code decoding to the outer coded packets in order to restore packets that were erased during transmission due to burst noise or other impairments on the channel. | 12-31-2009 |
20100296511 | Hierarchical Flow-Level Multi-Channel Communication - Embodiments herein provide systems and methods of transferring data in a communication system.

20110170632 | Digital Up-Converter and N-Channel Modulator With Flexible Association of QAM Generation Resources to Narrowcast and Broadcast Frequencies - Embodiments of a digital up-converter and an N-channel modulator are provided herein. The embodiments of the digital up-converter, in combination with the N-channel modulator, are capable of efficiently filling the spectrum of one or more RF signals with one or more types of information signals. For example, the digital up-converter can fill the spectrum of one or more RF signals with both broadcast and narrowcast video and data signals. In addition, the digital up-converter is capable of flexibly mapping the information signals to one or more channels of the one or more RF signals using a novel, three-level switching architecture. | 07-14-2011 |
20120039173 | Traffic Management In A Multi-Channel System - A method, system and computer program product in a downstream line card of a Cable Modem Termination System (CMTS) for managing downstream traffic for channels and bonded channel groups is provided herein. The method comprises the step of receiving packets for transmission to cable modems and classifying each packet to a flow based on class of service associated with the packet. The method further includes the step of storing the packets in flow queues based, wherein a flow queue is selected based on a flow a packet is associated with and wherein each flow corresponds to a single flow queue. The method also includes transmitting the packets from the flow queues to channel queues or bonded channel queues using corresponding channel nodes or bonded channel nodes at a rate that is determined based on feedback data and scheduling downstream transmission of packets on a single downstream channel if the packet is stored in a channel queue and on multiple downstream channels that are bonded together to form a bonded channel group if the packet is stored in a bonded channel queue. The feedback data is adjusted for each channel node or bonded channel node based on a queue depth for a corresponding channel queue or bonded channel queue. | 02-16-2012 |
20120257891 | Traffic Switching In Hybrid Fiber Coaxial (HFC) Network - Embodiments enable an Ethernet over Coaxial (EoC) Coaxial Media Converter (CMC) that implements only a subset of the functions (e.g., MAC and PHY) of a cable modem termination system (CMTS). The CMC sits between an optical line terminal (OLT) and a plurality of cable modems (CMs) that it serves. From the network management side at the OLT, the CMC appears and can be managed like an optical network unit (ONU). From the subscriber side, the CMC provides the same connectivity functions to the CMs as a CMTS and serves to terminate coaxial connections from the CMs. | 10-11-2012 |
20120257893 | Unified Network Management of Hybrid Fiber Coaxial (HFC) Network - Embodiments enable a network operator to use any (and a single) network management system (NMS) that it desires to manage a network having mixed fiber to the home optical network units (ONUs) and coaxial connected cable modems. For example, embodiments enable a cable company operator to use a DOCSIS (Data Over Cable Service Interface Specification) NMS (which the cable company already uses to manage its DOCSIS network) to manage such mixed network, by a simple addition of a DOCSIS Mediation Layer (DML) module between the NMS and the optical line terminal (OLT). On the other hand, embodiments enable a telephone company operator to use a standard EPON (Ethernet Passive Optical Network) OLT NMS with minor OLT and OAM (Operations, Administration, and Maintenance) protocol modifications to manage the same mixed network. | 10-11-2012 |
