碩士 === 朝陽科技大學 === 網路與通訊研究所 === 97 === The Stream Control Transmission Protocol (SCTP) proposed by IETF can improve problems in efficiency and security of TCP over network of transmitting data. But, SCTP transmission mechanism likes TCP, SCTP only use a single path to transmission, so, the utilization of network cannot be improved efficiently. Hence, research scholars proposed SCTP used concurrent multi-path transfer mechanism to increase the transmission performance, and they consider many network factors, ex: bandwidth, packet loss rate, delay, but, they do not considering load balancing in the CMT influences on average rate and receiver RWND. In this thesis, we modify the standard SCTP transmission mechanism, and we proposed ARD-CMT transmission mechanism to transfer data in different path, then, we implementation the ARD-CMT system on the linux platform, ARD-CMT transmission mechanism can increase the transmission performance, ARD-CMT based on the receiver RWND and average rate to calculation the weight. ARD-CMT based on the weight to achieve load balancing scheme. Finally, we used NIST NET to simulate environment factors reality, the simulation result shows that the ARD-CMT transmission mechanism can promotes the transmission performance, ARD-CMT provide a good mechanism for packet scheduling to achieve load balancing scheme
