Smooth transmission control protocol for streaming media
MA Hai-yuan · Computer Engineering and Applications Journal · 2012
In order to minimize the oscillations of sending rate for multimedia streaming, Smooth Transmission Control Protocol(STCP)is proposed. The receiver of STCP detects packets loss online. When there are some packets lost, the receiver estimates the capacity of the link between sender and receiver by the loss rate and sending rate currently. The sender uses the estimated capacity to adjust the sending smoothly. If there is no packet lost, the sending rate will increase by emulatingadditive increaseof TCP. Instead of cutting sending rate half when loss occurs, STCP decreases it according to the loss rate, which can guarantee the smoothness. Simulation results show that STCP has smooth sending rate and little delay jitter, and it has fine TCP-friendliness as well. STCP can be used for transmit-ting multimedia streaming.
