摘要： Systems and methods can use client-side video buffer occupancy for enhanced quality of experience in a communication network. The systems and methods provided herein can drive changes in the communication system using control responses. Example control responses include responses for scheduling of packets under capacity constrained conditions. An access node, such as a base station, may transmit video from a server to a client in a user device. The access node can estimate client-side video buffer occupancy and predict video playback stalls. The client-side video buffer occupancy can be estimated by emulating behavior of the client. The buffer occupancy can be used to enhance quality of experience for the user. For example, when the buffer occupancy is low, the access node may increase scheduling priority of packets conveying the video.

摘要： Access nodes and methods adjust a bit rate of a data stream in a communication network. The access nodes and methods have a packet inspection unit configured to inspect one or more of the data packets to determine that the data stream includes video data. A congestion unit is coupled to the packet inspection unit and is configured to determine a level of congestion in the communication network, the level of congestion associated with a capacity of the wireless channel, the level of congestion capable of varying over time, and the capacity of the wireless channel capable of varying with the level of congestion. A video scaling unit is configured to adjust the bit rate of the data stream responsive to the packet inspection unit and the congestion unit.

摘要： Systems and methods provide communications between applications in terminal nodes and applications agents in access nodes. The APP-agent cooperative communications can be used to improve quality of experience for users or the terminal nodes. An access node may, for example, have parameterized scheduling system that incorporates information from the APP-agent cooperative communications in determining scheduling parameters. An application at a terminal node may, for example, modify requests for communication based on information about communication capabilities received from an access node. For APP-agent cooperative communications for multiple applications, an access node may include a master application agent to facilitate and coordinate communications to specific application agents that address APP-agent cooperative communications for specific applications. Similarly, a terminal node may use a master application and specifications for APP-agent cooperative communications.

摘要： Systems and methods provide a parameterized scheduling system that incorporates end-user application awareness and can be used with scheduling groups that contain data streams from heterogeneous applications. Data packets are analyzed at multiple protocol levels to detect characteristics associated with communicating the packets. The data packets are filtered so that detecting the characteristics is efficiently performed. The detected characteristics can be used for scheduling transmission of the packets. The detected characteristics can be used to dynamically change scheduling parameters. The dynamic scheduling parameters can 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 parameters may also incorporate notions of "duration neglect" and "recency effect" in an end-user's perception of video quality in order to manage video traffic during periods of congestion.
