Research On Deep Packet Inspection Based On Distributed Cooperation Computing

In recent years,due to the development of the Internet,cloud computing technology has received more and more attention,the research of cloud computing is more and more in-depth,while the world's major IT companies have launched their own cloud computing services.Cloud computing has the advantages of high performance,scalability,low cost and user configurable,a large number of individual users and business users are beginning to use cloud computing services,but as a public data platform,data security has become the biggest obstacle to users.Deep packet inspection technology from the network layer to the application layer to complete the data security detection,its security performance is higher than the traditional packet filtering detection technology.It uses regular expressions to generate a finite state machine,and then the data packets are detected,and the real-time data can be tracked,detected and early warning.As a large public data platform,the distributed computing platform is very high in data security.The existing deep packet inspection technology research mainly focuses on the spatial usage rate of the algorithm.It has not improved the characteristics of the distributed computing platform.Therefore,it is inappropriate to apply the deep packet inspection technology directly to the distributed computing platform.Therefore,a new method for measuring the depth of the distributed computing platform is needed.Based on the research of the characteristics of cloud computing and the related technologies of deep packet inspection,this paper mainly focuses on the characteristics of the distributed computing platform,the user can configure,and the distributed mechanism.The main work of this paper is:1)introduced the basic concept of deep packet inspection technology and the principle of the algorithm used in the deep packet inspection technology,and deeply studied the implementation of these algorithms and the advantages and disadvantages of the algorithm.2)in order to study the XFA algorithm,the XFA algorithm is proposed,which is based on ACFA.The state of the XFA is divided into a new type of letter,and the position of the corresponding letter is recorded.3)combining with the characteristics of the distributed computing platform and the characteristics of the deep packet inspection technology,the combination of deep packet inspection technology and distributed computing platform is introduced.
