摘要:
A cable modem system and method is provided for the transfer and processing of data in accordance with specialized data transfer protocols while utilizing conventional cable modem termination system (CMTS) equipment. A cable modem system in accordance with the invention includes a cable modem that provides for the modification of data packets in accordance with one or more proprietary protocols and the addressing of the modified data packets to a CMTS. The CMTS is adapted to reconstruct the data packets.
摘要:
A dock system comprises a shore base with a train of disengageable dock module components comprising floatable modules with connector assemblies for releasably connecting the modules. The system includes laterally spaced posts, with lake bed engaging dock supporting base parts. The module components are vertically slidably on the posts to move from a lower floating position to a raised position safely above the water. A module transport device is operable to move the modules sequentially forwardly to form a train as the modules are sequentially connected or to move the modules sequentially rearwardly to remove them to shore as the modules are sequentially unlocked.

A method, system and computer program product for creating dynamic custom headers and for controlling flow rate of Downstream External Physical layer Interface (DEPI) packets are described herein. The method comprises concatenating or fragmenting a packet descriptor of a DEPU packet based on one or more of associated packet size, maximum transmission unit, packet type, channel configuration information and flow control mode. The method further comprises creating a header for the packet based on data in a programmable header template and storing the header in a header buffer, determining whether to transmit the packet based on one of a flow meter or a maximum transmission unit size and transmitting the packet by sending the packet descriptor to an output direct memory access (DMA) controller. A flow meter flow control mode determines if a packet is to be transmitted based on packet size, bucket size, a low threshold and a high threshold. A maximum transmission unit flow control mode determines if a packet is to transmitted based on packet size and a maximum transmission unit size. The header can be customized for Packet Streaming Protocol (PSP) mode or Moving Picture Experts Group Transport Stream (MPT) mode and includes dynamic customizable fields such as User Datagram Protocol (UDP) port identification, flow identification and session identification.
摘要:
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.

摘要:
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.
摘要:
An air cooled internal combustion engine has the usual intake radiator housing in front of its suction fan. A generally frustoconical body is mounted for rotation in front of the radiator. The body is made up of radially extending deflector fins extending outwardly in convergent relationship and spaced uniformly peripherally apart to provide elongate air entrance slits between them. Mechanism drives the body in rotation at a speed to deflect particles seeking to enter the slits without materially decreasing the rate of air flow created by the suction fan.
