Application Of Small Sample Data Mining In Soil Classification

With the deep integration of industrial revolution and a variety of Internet communication technologies,heterogeneous traffic transmission of hybrid network is growing exponentially.Multipath transmission technology(MPTCP)stands out by its huge advantages of multipath,high aggregation and low handover delay.The hybrid network transmission technology based on MPTCP mainly relies on its reliable congestion control mechanism to distinguish network congestion to ensure high-performance network transmission and load balancing.However,in the actual hybrid heterogeneous network,these existing mechanisms may underestimate the network congestion and cause the sender to blindly send data,which leads to the serious consequence of buffer blocking at the receiver.At the same time,the multipath asymmetric heterogeneity of heterogeneous network makes the MPTCP data scheduling mechanism unable to obtain accurate information related to congestion degree,which leads to packet disorder,thus causing HOL blocking problem.Therefore,according to the actual congestion situation of heterogeneous networks,this paper will build a congestion control algorithm cache model,optimize the congestion control strategy to solve the buffer problem exposed by the existing MPTCP congestion mechanism in the hybrid network,and design an accurate data distribution scheduling strategy to solve the HOL congestion problem caused by the disorder of data packets,so as to bring ultra-low time to the hybrid network In order to achieve the purpose of optimizing the MPTCP transmission technology in the hybrid network,the network congestion and load imbalance are further improved.The main research contents are as follows.First of all,this paper explores the MPTCP technology in hybrid network.Through theoretical research and experimental analysis,it mainly analyzes the causes of buffer expansion and HOL blocking in hybrid network from two aspects of congestion control and data scheduling.At the same time,according to the design principles of MPTCP technology,it analyzes in detail the shortcomings of existing congestion control mechanism and data scheduler exposed to the hybrid network In this paper,we summarize and discuss the solutions based on the challenges brought by MPTCP transmission technology.Secondly,through the analysis of the existing congestion algorithms in heterogeneous networks by HMM algorithm,the potential problems caused by MPTCP congestion mechanism are proposed.Combined with the cache rules of MPTCP congestion algorithm,the cache process of the receiver is abstracted concretely,an improved cache blocking model is constructed,and the logarithmic function relationship between the real-time throughput and the cache area is defined,which can be used dynamically The buffer value is calculated according to the network transmission performance.Combined with BPMF scheme,the improved MPTCP congestion algorithm is constructed.Combined with dynamic sensing cache value and real-time time time series prediction,the real network congestion state of heterogeneous network is distinguished.The ns-3 simulation experiment verifies its effectiveness to ensure the efficient operation of the network.Finally,combined with the state correlation of congestion window changes,through the real-time analysis of multipath asymmetric links,combined with the best path selection and buffer management,the MPTCP data scheduling strategy is constructed to supplement the congestion control,and the specific scheduling measures are given for different data sequences to solve the HOL congestion problem caused by the disorder of data packets,so as to improve the network efficiency The ns-3 simulation results show the effectiveness and rationality of the multipath scheduling strategy.
