Minimum Rate Distortion Based Scheduling over UDP for Single Nested Streaming Media
TCP seems helpless, facing fast-growing high bit- internet applications like streaming media. But UDP, alternative choice, lacks congestion control and does guarantee packets arrival. We study the UDP transmission situation by experiments, and build the mathematic and physical models. Then we propose minimum rate distortion based scheduling for streaming media. Considering the structure of single nested streaming and the packet lost rate curve of the UDP transmission, we estimate the minimum rate distortion determine the max retransmission of a packet and the max traffic within a GOP which can be sent through the internet, finally gain good transmission performance, but without UDPs natural behavior of sacking the bandwidth unfairly.
