The performance of a CMT association degrades remarkably when the transmission capabilities of its paths are diverted. Based on the analysis of different network configurations, a transmission delay prediction based data allocation scheme is proposed to distribute data to different paths with a feasible delay measurement mechanism. To reduce the impact brought by out of order packet, the proposed scheme improves the data distribute process of inter and intra transmission round by accessing and predicting the arriving time of each packet in each path. The result of analysis and simulation reveal the performance of the presented scheme can achieve much better performance than the original round-robin scheme.
