碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 97 === In this thesis, we propose a Partially Reliable-Concurrent Multipath Transfer (PR-CMT) that is featured with artially reliable multi-path transmission and prioritized stream transmission based on the Concurrent Multipath Transfer (CMT) and the Stream Control Transmission Protocol Partial Reliability Extension (PR-SCTP). PR-CMT is devised for real-time application data with different importances and time constraint. Data in PR-CMT are associated with lifetime. Steams in PR-CMT are associated with priorities. When the lifetime of data is expired, PR-CMT would not transmit and retransmit the lifetime expired data. Higher priority streams are transmitted before lower priority treams. Thus, the transmission of higher priority data would not be blocked by lower priority data. On the other hand, the proposed PR-CMT is able to eliminate the false acked Transmission Sequence Numbers (TSNs) problem and sender induced FORWARD TSN reordering. The simulation results show that PR-CMT (i) is more resistant to the high loss rate environment, (ii) can guarantee the ransmissions of higher priority streams, (iii) and can increase the transmission efficiency.
