Adaptive redundancy control for systematic erasure code based real time data transmission in Internet

We propose an adaptive redundancy control scheme for a systematic erasure coding scheme to transmit real time data in the Internet. Since the recovery rate of packet loss depends on the amount of redundancy data, we use the redundancy estimation algorithm which considers the loss burstiness. The Gilbert model is used for modeling the loss process and adjusting the number of redundant packets. Analysis and experimental results show that the proposed scheme is efficient for loss recovery in a consecutive loss environments like the Internet.
