摘要： In one example, a Cable Modem Termination System (CMTS) sends first bandwidth allocation messages to a first upstream transmit interface on a cable modem and send second bandwidth allocation messages to a second upstream transmit interface on the cable modem. The bandwidth allocation messages indicate transmit windows for the cable modem to range over the interfaces. The transmit windows included in the first bandwidth allocation messages are spaced based on receipt of ranging requests from the second upstream transmit interface, and the transmit windows included in the second bandwidth allocation messages are spaced based on receipt of ranging requests from the first upstream transmit interface.

摘要： A Data Over Cable Service Interface Specifications (DOCSIS) Passive Optical Network (PON) system (DPON) makes optical subscribers appear as cable subscribers. In one embodiment, a Cable Modem (CM) proxy is located in an Optical Line Termination (OLT). The OLT implements a cable modem protocol stack that operates as the CM proxy and communicates with a back office system. The OLT translates the data retrieved by the CM proxy into Optical Network Unit (ONU) recognizable commands, and sends the translated data to the ONU. In a second embodiment, the CM proxy is located in the ONU. The ONU implements the cable modem protocol stack that operates as the CM proxy and communicates with the back office system. The ONU translates the data retrieved by the CM proxy into ONU recognizable commands and sends the translated data to the ONU.

摘要： Systems and methods for retransmitting unsuccessfully transmitted data across a communication link. The retransmission mechanism may be applied to point to multipoint networks including wireless networks. Each packet is encapsulated in an ARQ frame and assigned a sequence number for the purpose of coordinating acknowledgments and retransmissions. Information as to which packets require retransmission is communicated in the form of a bitmap where each bit indicates an acknowledgment status for a given packet. Any missing packets in the received sequence are assumed to require retransmission.

摘要： A modular Cable Modem Termination System (CMTS) includes a packet shelf operating a Data Over Cable Service Interface Specifications (DOCSIS) Media Access Control (MAC) framer. One or more downstream Physical Interface (PHY) shelves receive DOCSIS data from the packet shelf over a packet switched network and modulate the DOCSIS data for sending on a downstream path of a cable plant. One or more upstream PHY shelves send DOCSIS data received from an upstream path of the cable plant over the packet switched network to the packet shelf. By separating the PHY components from the MAC and from the system software, the PHY components for a Hybrid Fiber Coax (HFC) plant may be replaced with different PHY components for other access technologies such as wireless, Digital Subscriber Lines (DSL), Ethernet-to-the-Home, Fiber-to-the-Home, or fiber Passive Optical Networks (PONs).

摘要： A technique for managing the distribution of digital video content to multiple end-user devices is disclosed. The technique involves statistically multiplexing multiple VBR encoded video streams into an access channel, such as a data over cable service interface specifications (DOCSIS) bonded group, and utilizing quality of service capabilities of an edge device, such as a cable modem termination system (CMTS) or an edge quadrature amplitude modulation (QAM) device, to buffer and schedule IP packets, which carry the VBR encoded video streams, so that packets are not dropped during periods of congestion. Utilizing the quality of service capabilities of an edge device makes it possible to statistically multiplex VBR encoded video streams in a narrowcast application such as Video on Demand (VOD) or Switched Digital Video (SDV) while eliminating the need for process intensive transrating/transcoding operations.
