Research On The Data Copy Securityin Data Center Network And Its Application In Smart Logistics Platform

In recent years,smart cloud logistics that integrates cloud computing,big data,and internet of things technologies has rapidly penetrated into people's daily life.The logistics industry needs a comprehensive,fast,convenient,and highly secure smart logistics service model urgently.Based on this,this paper first proposes two different theoretical research methods for data replication mechanism in data center networks.Finally,we analyze the case of a data replication mechanism that is applicable to the smart cloud logistics information platform.This paper first establishes the data replication mechanism model in the data center network,and then uses the given model variable to calculate the steady-state probability distribution of the number of normal-running data centers in the data center network and the random behavior of the number of copies of file data.At the same time,this paper indicates that the number of copies of file data in the data center network is directly affected by the number of normal operating data centers.Secondly,expanding the model random variable to a more general situation: The data center's lifespan and file data's replication time are extended from exponential distribution to PH distribution;The new data center's joining process is extended from Poisson process to Markov's arrival process.In this case,our model is more in line with the actual situation.At the same time,the method to calculate the number of steady-state normal operation data centers and their lifetime is given.Finally,the accuracy of the theoretical results is proved by RG-decomposition method.Finally,this paper applies the research results to the smart cloud logistics platform of Jingdong Mall;It analyzes the number of servers and the lifespan of the smart cloud logistics platform of Jingdong Mall in normal operation;It ensures the security and effectiveness of logistics information data.Therefore,the research in this paper is an extremely important and theoretically important research direction in the field of data security in the smart cloud logistics information platform.
