Patent number: 8811271Abstract: In a satellite gateway, data is transmitted over a downstream channel at different throughput rates. Data destined for each subscriber/receiver is assigned a throughput rate depending upon the downstream signal quality of that subscriber/receiver. The downstream data is parsed to extract data packets. The data packets are then loaded into packet queues based on an identifier within such packets. The queues represent a bandwidth efficiency or throughput rate that can be currently tolerated by specific subscribers that may also be based on the current signal quality at a subscriber location. The parsed data traffic is processed based on the profile of the plurality of profiles to produce processed data traffic, and transmitted from the packet queues over a downstream channel.Type: GrantFiled: May 31, 2013Date of Patent: August 19, 2014Assignee: Broadcom CorporationInventors: Mark Dale, Anders Hebsgaard, David Hartman, Alan Kwentus, Steven Jaffe, Kelly Cameron, Stephen Krafft, Alan Gin, Jen-chieh (Jack) Chien, Dorothy Lin, Rocco Brescia, Joyce Wang

Publication number: 20140023097Abstract: A downstream adaptive modulation system and method. The downstream adaptive modulation system comprises a wireless access termination system and one or more wireless modems. The wireless access termination system includes a plurality of queues and a parser. The parser parses data traffic onto the plurality of queues. Each queue is associated with a different coding and modulation scheme. Each of the one or more wireless modems receives data traffic from the plurality of queues based on the wireless modem's ability to demodulate and decode the signal from each of the plurality of queues. When a wireless modem experiences a change in signal strength, the present invention enables the wireless modem to adapt to data from other queues to compensate for the change in signal strength. Thus, if the signal strength improves over a period of time, the wireless modem may receive data at a higher order modulation and FEC code rate.Type: ApplicationFiled: September 20, 2013Publication date: January 23, 2014Applicant: Broadcom CorporationInventors: Mark Dale, David Hartman, Anders Hebsgaard

Patent number: 8005072Abstract: A plurality of CMTS devices are linked together and synchronized to facilitate communication between the respective CMTS devices and respective downstream cable modems. According to one embodiment of the invention, one of the CMTS devices is designated as a master device, and the other CMTS devices are designated as slave devices. The respective CMTS devices are connected to each other by means of a synchronization bus. The master CMTS device then generates and broadcasts a future time stamp value, which is received by the respective slave CMTS devices. When the time stamp counter in the master CMTS device reaches the transmitted value, a control signal is broadcast over the synchronization bus. The slave CMTS devices then retrieve the time stamp value and reset their respective local time stamp counters to the received value. In this manner, the CMTS devices are synchronized.Type: GrantFiled: March 30, 2006Date of Patent: August 23, 2011Assignee: Broadcom CorporationInventors: Anders Hebsgaard, David R. Dworkin, Lisa V. Denney, Robert J. Lee, Thomas J. Quigley

Patent number: 7822037Abstract: Upstream requests such a bandwidth requests, are processed by CMTS out of order on a priority basis to reduce latency in responding to the request. Specifically, a cable modem termination system (CMTS) is connected to a plurality of cable modems by a cable plant. The CMTS has a burst receiver adapted to be connected to the cable plant to process upstream data packet units and bandwidth requests transmitted by the cable modems. Each packet includes a header that uniquely distinguishes the bandwidth requests from other data types. Packet data units are arranged in a first memory queue. Bandwidth requests are arranged in a second memory queue. The headers of the packets processed by the burst receiver are inspected as they arrive at the CMTS to determine if the packets are packet data units or bandwidth requests. Packet data units are routed to the first memory queue. Bandwidth requests are routed to the second memory queue.Type: GrantFiled: August 7, 2007Date of Patent: October 26, 2010Assignee: Broadcom CorporationInventors: Lisa V.

Publication number: 20100074167Abstract: In a DOCSIS based satellite gateway data is transmitted over a single downstream channel, at different throughput rates. Data destined for each subscriber/receiver is assigned a throughput rate depending upon the downstream signal quality of that subscriber/receiver. To accomplish this, the downstream DOCSIS MAC data is parsed to extract DOCSIS packets. The DOCSIS packets are then loaded into packet queues based on an identifier within such packets such as the MAC destination address or SID. Each of the queues represents a bandwidth efficiency or throughput rate that can be currently tolerated by specific subscribers based on the current signal quality being experienced at the subscriber location. A PHY-MAP describing the downstream data structure to be transmitted and inserted into the downstream data. Data is extracted from the packet queues in queue blocks as defined by the PHY-MAP.Type: ApplicationFiled: March 23, 2009Publication date: March 25, 2010Applicant: Broadcom CorporationInventors: Mark Dale, Anders Hebsgaard, David Hartman, Alan Kwentus, Steven Jaffe, Kelly Cameron, Stephen Krafft, Alan Gin, Jen-chieh (Jack) Chien, Dorothy Lin, Rocco Brescia, Joyce Wang
