摘　　要：针对异构网络数据的缓冲存储效率低、分区存储精准度、运行代价高等问题,提出异构网络数据缓冲区替换算法的数学模型。首先将异构网络数据划分为多个数据阶层,确定数据格式,同时利用新的异构网络数据传输途径控制传输链路,对控制算法的窗口大小进行计算,以此梳理数据。最后将缓冲区分为冷区与热区两部分,分析算法的干扰因素,利用交替算法完成异构网络数据缓冲区替换算法的数学建模。仿真结果表明,基于异构网络数据缓冲区替换算法的数学模型可以有效提升算法的效率和精准度,同时可以降低算法运行代价。Due to low efficiency of buffer storage, high accuracy of partition storage and high running cost of het-erogeneous network data, a mathematical model of buffer replacement algorithm for heterogeneous network data waspresented. Firstly, the heterogeneous network data were divided into several data layers, and thus to determine thedata format. Meanwhile, the new transmission path was used to control the transmission link, and then the windowsize of the control algorithm was calculated to comb out the data. Finally, the buffer area was divided into two parts:cold area and hot area. After the interference factors of algorithm were analyzed, the alternating algorithm was used tobuild mathematical model of data buffer replacement algorithm in heterogeneous network. Simulation results show thatthe designed mathematical model can effectively improve the efficiency and accuracy of algorithm, and thus reducethe operating cost.
