  • Publication number: 20060126660
    Abstract: 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.

  • Publication number: 20050182866
    Abstract: A system and method for hardware based reassembly of a fragmented packet is shown. The method includes receiving a bandwidth request to transfer a data packet from the data provider. Then, bandwidth is allocated to the data provider, where the allocated bandwidth is less than the requested bandwidth. Next, the present invention receives part of the data packet in the allocated bandwidth from the data provider, where the part of the data packet includes a fragment header, and the fragment header includes a sequence number for the part of the data packet. The part of the data packet is then stored in external memory. Finally, the data packet is reassembled by concatenating in the correct sequence the part of the data packet with other parts of the data packets to create the reassembled data packet.

  • Publication number: 20050097617
    Abstract: A cable modem communication system includes a plurality of Cable Modems (CMs), a CM network segment, and a Cable Modem Termination System (CMTS). The CMTS segregates the plurality of CMs into a first group of CMs with which standard registering and ranging operations are performed and a second group of CMs with which attenuated transmission registering and ranging operations are performed. Each CM of the first group of CMs operable to perform registering and ranging operations by transmitting a ranging burst of a first format. Each CM of the second group of CMs operable to perform registering and ranging operations by transmitting a ranging burst of a second format that differs from the ranging burst of the first format. The CMTS may include a rake receiver that receives and demodulates a plurality of multi-path copies of the ranging burst of the second format.

  • Publication number: 20040202202
    Abstract: A central entity and/or a remote device in a communication system are designed to address the problem of maintaining upstream synchronization in the remote device after loss of the downstream signal. One issue of particular importance is maintaining upstream transmissions from the remote device in an S-CDMA (or perhaps S-TDMA) mode that do not degrade performance of the communication system via poor upstream timing or a need for re-ranging. By providing novel functionality at the central entity for synchronizing first and second downstream signals and/or by providing novel functionality at the remote device for determining a symbol clock offset between a first terminated downstream signal and a second re-acquired downstream signal, embodiments of the present invention facilitate maintenance of synchronization through the loss of the downstream signal, thereby minimizing the need for re-ranging and avoiding poorly timed upstream bursts.

  • Publication number: 20040100985
    Abstract: A system and method is presented for reuseing its S-CDMA related hardware (e.g., timestamp, minislot and frame count hardware) to create an extended mode to DOCSIS 2.0, namely to allow the TDMA channel to have any minislot size as is afforded to the S-CDMA channel. This reuse of existing S-CDMA hardware to create the extended mode is accomplished without the burden (e.g., complexity, cost, and schedule) of additional hardware to perform a separate set of calculations. In order to accomplish the foregoing, parameters are determined to use in a S-CDMA-type UCD message such that when that UCD message is interpreted by both the cable modem and CMTS hardware as though it were an S-CDMA message, the result is an TDMA minislot size that represents a desired integer number of ticks per minislot. In addition, the system and method periodically constructs the relationship between the system timestamp count, a channel's minislot count and the frame count via a timestamp snapshot.

  • Publication number: 20030058837
    Abstract: A traffic prioritization system performs a coarse classification of upstream bursts at the physical interface of a headend communications device. The headend device monitors and controls communications with a plurality of remote communications devices throughout a widely distributed network, including the Internet. The traffic prioritization system includes a burst receiver that receives and sends the upstream bursts to a classifier. At an appropriate time, the classifier receives the upstream bursts and queries a priority lookup table (LUT) to determine a priority classification. The priority classification is used to separate the bursts into two or more priority levels. The higher priority level is used to designate services having a low tolerance for delay, such as telephony. Upon classification, the upstream bursts are forwarded to one of several priority queues. Each priority queue corresponds to at least one priority level.

  • Publication number: 20030058892
    Abstract: A supervisory communications device, such as a headend device within a cable communications network, monitors and controls communications with a plurality of remote communications devices, such as cable modems, throughout a widely distributed network, including the Internet. The supervisory device establishes the upstream slot structure and allocates upstream bandwidth by sending UCD and MAP messages over its downstream channel. The supervisory device also uses the MAP messages and minislot counts to anticipate bursts from the remote devices. Dual registers are provided within the supervisory device to generate minislot counts. A primary register generates minislot counts for a current slot structure, and a secondary register generates minislot counts for a revised slot structure. Software executed on the supervisory device determines a switchover time for changing to the revised slot structure and revised minislot count.

  • Publication number: 20030058794
    Abstract: A system and method is presented to utilize hardware instead of software to compare for bandwidth request changes between two consecutively received unsolicited grant service (UGS) extended headers for the same service identifier (SID), obtains significant savings in CPU cycles for the CMTS software. The system determines whether adequate bandwidth is being provided from a cable modem termination system to a data provider during a unsolicited grant service flow. The system includes a means for receiving a current voice packet in the unsolicited grant service flow at the cable modem termination system from the data provider, where the current voice packet comprises a unsolicited grant service extended header. The system further includes means for comparing the current unsolicited grant service extended header with a previous unsolicited grant service extended header.

  • Publication number: 20030058795
    Abstract: A method and system for dropping lower priority packets for transmission over a communication medium is provided. A cable modem termination system receives one or more packets to be transferred to one or more data providers, each packet having a priority. Then, based on the priority, a media access controller stores each of the packets in one or more priority queues in a fixed shared memory space in such a way as to maintain the order in which the packets were received in each of the priority queues. The media access controller monitors the number of packets in each of the priority queues and signals an interrupt when a packet threshold is exceeded in one or more of the priority queues. The media access controller then drops lower priority packets in the fixed shared memory space based on the order received to guarantee that there is enough memory to store higher priority packets in the fixed shared memory space.
