基于多路径并行传输的数据乱序分析改进模型

bstract In concurrent multipath transmission system, The asymmetry of bandwidth and delay between different links can leads to the sequence of packet arrival at the receiver will not be exactly the same as the sending sequence of the sender, and this causes a phenomenon of packet reordering, and this will lead to unnecessary retransmission, reducing the network resource utilization. The problem of packet reordering in concurrent multipath transmission will be analyzed, this paper consider the influence of the transmission delay of data packet toreordering analysis model, put forward a kind of packet reordering analysis model in concurrent multipath transmission based on the cumulative probability distribution function, otherwise, a constraint conditions are derived for data packets to be transmitted in order. And the calculation formula of random order probability of data packet in concurrent multipath transmission. The analysis of the packet reordering is more close to the reality, which provides the research direction for the performance optimization of the concurrent multipath transmission.
