Patent number: 9237030Abstract: A cable modem that supports stateless requesting and/or limited contention-based requesting is provided herein. In an example, a physical layer (PHY) configured to communicate over a plurality of upstream channels is provided. A bandwidth requester is provided to request bandwidth using contention-based requesting over a first subset of the upstream channels for contention-based flows and request bandwidth using stateless requesting over a second subset of the upstream channels for stateless flows.Type: GrantFiled: August 20, 2012Date of Patent: January 12, 2016Assignee: Broadcom CorporationInventors: Niki Pantelias, Lisa Denney, Edward Boyd, Andres Alvarez, Scott Hollums

Patent number: 9020014Abstract: A cable modem termination system (CMTS) is disclosed that allocates one or more minislots of a super-frame arrangement to cable modems for upstream transmission. The super-frame arrangement includes multiple minislots that correspond to multiple communication channels of one or more super-frames. The CMTS receives requests for upstream bandwidth from the cable modems. The CMTS continuously allocates the minislots of the super-frame to provide upstream bandwidth grants to accommodate these requests. The CMTS communicates the upstream bandwidth grants as a single upstream bandwidth allocation map (MAP) to the cable modems.Type: GrantFiled: December 30, 2011Date of Patent: April 28, 2015Assignee: Broadcom CorporationInventors: Niki Pantelias, Scott Hollums

Patent number: 8908716Abstract: A method for increasing upstream bandwidth per cable modem user in a cable communications system that includes a cable modem termination system (CMTS) and a plurality of cable modems is provided. The method permits a cable modem to transmit data to the CMTS on multiple upstream channels simultaneously using a technique called “channel bonding.” Channel bonding allows smaller bandwidth upstream channels to be bonded together to create a larger bandwidth pipe.Type: GrantFiled: September 14, 2012Date of Patent: December 9, 2014Assignee: Broadcom CorporationInventors: Lisa Voigt Denney, Niki Roberta Pantelias, A.

Patent number: 8705567Abstract: A method for increasing upstream bandwidth per cable modem user in a cable communications system that includes a cable modem termination system (CMTS) and a plurality of cable modems is provided. The method permits a cable modem to transmit data to the CMTS on multiple upstream channels simultaneously using a technique called “channel bonding.” Bandwidth allocation is achieved by transmitting from a CMTS to a cable modem a unique bandwidth allocation message for each upstream channel in a bonded group of upstream channels, wherein the combination of unique bandwidth allocation messages collectively allocates requested bandwidth across the bonded group.Type: GrantFiled: March 21, 2006Date of Patent: April 22, 2014Assignee: Broadcom CorporationInventors: Lisa Voigt Denney, Niki Roberta Pantelias, A.

Patent number: 8537696Abstract: A system and method are presented for changing physical layer (PHY) parameters in a PHY device of a communications system. New parameters are written to a first-in first-out queue in a serial interface, while the scheduled time for the changeover is written to a control register in the serial interface. When the time for the changeover occurs, the parameters are written to the PHY device via a port of the serial interface.Type: GrantFiled: October 3, 2007Date of Patent: September 17, 2013Assignee: Broadcom CorporationInventors: A.

Patent number: 7958431Abstract: A system and method is provided for interleaving data in a communication device. The system includes a memory that stores blocks of data to be interleaved. In addition to the memory, the system includes a write module and a read module, each of which is coupled to the memory. The write module is configured to receive a burst of data and write blocks of data from the burst into the memory. The write module is also configured to provide control information to the read logic. The control information includes a rolling burst counter and a burst profile bank identifier for each block. If interleaving is activated, the control information also includes information pertaining to how the read module should interleave the block. If interleaving is not activated, the control information also includes the byte length size of the burst. The read module reads blocks of data from memory in either an interleaved fashion or a non-interleaved fashion in accordance with the control information.Type: GrantFiled: December 12, 2007Date of Patent: June 7, 2011Assignee: Broadcom CorporationInventor: Scott Hollums

Patent number: 6928109Abstract: Requests are processed to transmit data packets upstream from a cable modem to a cable headend in a manner that minimizes the use of CPU operations and/or memory capacity. Data packets to be transmitted upstream are stored at the cable modem. The data packets each have a given transmission data byte length value. Burst profiles are received successively at the cable modem. Each time a new bust profile is received, a set of physical data length values corresponding to respective transmission data byte length values is calculated from the parameters of the received burst profile. The calculated set of physical data length values is stored in memory so the individual values can be retrieved from the transmission data byte length values again and again, rather than being re-calculated each time a conversion is made from transmission data byte length values to physical data length values. The same set of physical data length values is used until a new burst profile is received by the cable modem.Type: GrantFiled: May 27, 2003Date of Patent: August 9, 2005Assignee: Broadcom CorporationInventors: John Daniel Horton, Jr., Scott Hollums, Chris Roussel
