Abstract:

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 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.

H04W 40/00

US Classification:

455445, 455428, 4554521, 4554522, 370252

Abstract:

A communication station, such as a base station or access point, has multiple backhaul options and distributes backhaul data between the available backhaul options. The communication station includes a transceiver for transmitting and receiving data with user equipments, multiple backhaul interface modules, and a backhaul distribution module arranged for monitoring demand for backhaul bandwidth and distributing data over the backhauls based on the demand for backhaul bandwidth. Additional modules for user data and control plane processing may be included with the user/control distinction used in distributing data over the backhauls. The backhaul options may include a preferred backhaul and an alternate backhaul. Distributing data over the backhauls may be based, for example, on applications associated with the data, financial cost, delay, robustness, computational resources, and/or additional security associated with using a particular backhaul.

Abstract:

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.

International Classification:

H04W 28/02

US Classification:

370235

Abstract:

Systems and methods provide a weight-based scheduling system that incorporates end-user application awareness 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. Dynamic AF settings may adjust relative importance of user applications to maximize user Quality of Experience (QoE) in response to recurring network patterns, one-time events, application characteristics, protocol characteristics, device characteristics, service level agreements, or combinations thereof. Scheduling weights may be dynamic and incorporate the notions of “duration neglect” and “recency effect” in an end-user's perception of video quality in order to optimally manage video traffic during periods of congestion.

Abstract:

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.
