摘要： Media-aware and TCP-compatible bandwidth sharing may be provided. In various embodiments, a network node may periodically update a virtual congestion level for a transmission stream in a network. The transmission stream may comprise at least one video stream and at least one data stream. The network node may then calculate, based at least in part on the virtual congestion level, a random packet marking probability or a random packet drop probability. In turn, the network node may either drop or mark transmission packets according to the calculated marking and dropping probability. The network node may further calculate an optimal video transmission rate for the at least one video stream and adjust a video transmission rate for the at least one video stream accordingly. Rate-distortions parameters for the at least one video stream may influence the optimal video transmission rate calculation for the at least one video stream.

摘要： The described system and method provide joint rate control and scalable stream adaptation for multiple clients concurrently competing for the same access networks. For each such client, an optimization problem is constructed and solved to determine the streaming rate over each access network, the video packets to be transmitted, and the access network over which each video packet is sent. The rate control and stream adaptation problem is constructed as an integer program in an embodiment of the invention, with an objective to minimize a cost function of the expected video distortion. Randomized packet scheduling is accounted for in an embodiment of the invention by relaxing the integer program into real-valued optimization programs and deriving convex programming approximations.

摘要： Media-aware and TCP-compatible bandwidth sharing may be provided. In various embodiments, a network node may periodically update a virtual congestion level for a transmission stream in a network. The transmission stream may comprise at least one video stream and at least one data stream. The network node may then calculate, based at least in part on the virtual congestion level, a random packet marking probability or a random packet drop probability. In turn, the network node may either drop or mark transmission packets according to the calculated marking and dropping probability. The network node may further calculate an optimal video transmission rate for the at least one video stream and adjust a video transmission rate for the at least one video stream accordingly. Rate-distortions parameters for the at least one video stream may influence the optimal video transmission rate calculation for the at least one video stream.
