Patent number: 8627396Abstract: Systems and methods for optimizing system performance of capacity and spectrum constrained, multiple-access communication systems by selectively discarding packets are provided. The systems and methods provided herein can drive changes in the communication system using control responses. One such control responses includes the optimal discard (also referred to herein as “intelligent discard”) of network packets under capacity constrained conditions. Some embodiments inspect a video stream to determine priorities for various elements of the video stream. The elements may be discarding using the priorities. In various embodiments, the elements include frames, slices, macroblocks, and data partitions.Type: GrantFiled: June 7, 2011Date of Patent: January 7, 2014Assignee: Cygnus Broadband, Inc.Inventors: Kenneth Stanwood, David Gell

The systems and methods provided herein can drive changes in the communication system using control responses. One such control responses includes the optimal discard (also referred to herein as “intelligent discard”) of network packets under capacity constrained conditions. The systems and methods prioritize packets and make discard decisions based upon the prioritization. Some embodiments provide an interactive response by selectively discarding packets to enhance perceived and actual system throughput, other embodiments provide a reactive response by selectively discarding data packets based on their relative impact to service quality to mitigate oversubscription, others provide a proactive response by discarding packets based on predicted oversubscription, and others provide a combination thereof.Type: GrantFiled: July 14, 2011Date of Patent: September 10, 2013Assignee: Cygnus Broadband, Inc.Inventors: Kenneth Stanwood, David Gell

Publication number: 20130142055Abstract: Systems and methods preserve application identification information on handover in a communication network. End user quality of experience is improved by determining applications associated with communications to and from the end user. The applications may include application classes and specific applications. The application information is used to schedule packets such that the end user quality of experience is improved for that application. When the end user is handed over between wireless access nodes, the access nodes transfer application information so that the improved end user quality of experience is maintained.Type: ApplicationFiled: December 6, 2011Publication date: June 6, 2013Applicant: CYGNUS BROADBAND, INC.Inventors: Yiliang Bao, Kenneth Stanwood, David Gell

Publication number: 20120327778Abstract: Systems and methods for providing a weight-based scheduling system that incorporates end-user application awareness are provided and can be used with scheduling groups that contain data streams from heterogeneous applications. Individual data queues within a scheduling group can be created based on application class, specific application, individual data streams or some combination thereof. Application information and Application Factors (AF) are used to modify scheduler weights to differentiate between data streams assigned to a scheduling group. One embodiment adjusts the relative importance of different user applications using dynamic AF settings to maximize user Quality of Experience (QoE) in response to recurring network patterns, one-time events, or both.Type: ApplicationFiled: June 22, 2011Publication date: December 27, 2012Applicant: CYGNUS BROADBAND, INC.Inventors: Kenneth Stanwood, David Gell

Publication number: 20120140730Abstract: An advanced technology frame structure is described herein. The advanced technology frame structure can enhance a first technology frame structure in dimensions of time, frequency, or a combination of time and frequency. A second technology frame structure time division multiplexes second technology subframes with the first technology downlink and uplink subframes. The first technology downlink subframe can be divided into a first technology downlink subframe and one or more second technology downlink subframes. Similarly, the first technology uplink subframe can be divided into a first uplink subframe and one or more second technology uplink subframes.

Publication number: 20120013748Abstract: Capacity and spectrum constrained, multiple-access communication systems optimize performance by selectively discarding packets. Changes in the communication systems may be driven using control responses. Control responses include intelligent discard of network packets under capacity constrained conditions. Packets are prioritized and discard decisions are made based on the prioritization. Various embodiments provide an interactive response by selectively discarding packets to enhance perceived and actual system throughput, provide a reactive response by selectively discarding data packets based on their relative impact to service quality to mitigate oversubscription, provide a proactive response by discarding packets based on predicted oversubscription, or provide a combination thereof. Packets may be prioritized for discard using correlations between discards and bandwidth reduction and quality degradation. The quality degradation for video packets may be measured objectively.Type: ApplicationFiled: September 23, 2011Publication date: January 19, 2012Applicant: CYGNUS BROADBAND, INC.Inventors: Kenneth Stanwood, David Gell, Yiliang Bao

Patent number: 7672268Abstract: In a system utilizing double wide communication channels, if a particular CPE requires a sustained rate that is greater than the bandwidth of a single channel, data to and from the CPE may be split across Channels A and B. Also, when the bandwidth requirements of a particular CPE peaks at a data rate greater than the capacity of a single channel, the CPE's data may be split across the two channels. In one embodiment, a single-wide CPE may communicate with the base station without knowing that it is communicating with a base station configured to communicate using a double wide channel.Type: GrantFiled: June 17, 2005Date of Patent: March 2, 2010Inventors: Kenneth Stanwood, Timothy Leo Gallagher, Sheldon L.

Patent number: 7609631Abstract: A method and system for prioritizing connection data that is associated with different classes of service for transmission in a frame based communication system. These classes of service can include CBR, nrt-VBR, MGR, and UBR traffic. One embodiment of the scheduling method and system uses hierarchical round-robin (HRR) with deficit round-robin (DRR). In this embodiment, the scheduling method and system guarantees minimum rates of nrt-VBR and MGR traffic to the connections. The excess bandwidth is then fairly allocated between the existing connections and their classes of service. For example, the excess is allocated for UBR traffic and for the excess demands of the nrt-VBR and MGR connections. In one embodiment, the scheduling method and system allocates the excess bandwidth in a frame to the existing connections using weighted round robin to differentiate between different classes of service.Type: GrantFiled: February 5, 2007Date of Patent: October 27, 2009Inventors: Kenneth Stanwood, George Lin, Yair Bourlas

Patent number: 7577100Abstract: The system and method optimizes a SNR calculation for a signal received during a downlink burst even in the absence of a node's preferred modulation. This system and method are used in communication systems that include a multi-modulation modem. An adaptation factor is selected whereby its use during portions of the downlink burst, which were not modulated using the preferred modulation, provides the SNR. The selected adaptation factor is used by an equalizer to perform channel inversion to the signal. The system and method can be used in, for example, an FDD or TDD communication system. Such communication systems can be, for example, symmetric, asymmetric, and/or adaptive in their operation.Type: GrantFiled: July 26, 2002Date of Patent: August 18, 2009Inventors: Stephen Pollmann, Kenneth Stanwood, David Gazelle
