As the growth of network based applications and services, the amount of data transmissions on the network is much more than ever. Transmission control is an important part of the Internet or other computer networks today. Network coding can help to optimize the efficiency of data transmissions by generating the redundant data for error correction. In this paper, we proposed the loss-rate driven coding, LRC, for transmission control. The goal of proposed mechanism is to minimize the coding operations. As a result, the power consumption and computing resource requirement can be reduced. Moreover, the proposed mechanism is compatible with standard TCP and feasible to implement.
