Architecture Design And Realization Of Distributed Identity Resolution System For Industrial Internet

With the expansion of Industrial Internet coverage and the explosive growth of identifier registration,the requirements for identification and resolution system are increasing.This thesis aims to solve the problems of centralization,scalability,security and performance of identification and resolution network in the existing identification and resolution system,focus on the technical innovation of identification and resolution system,integrate the cutting-edge solutions of the Internet,and create a distributed interconnection neural hub for the Industrial Internet.This thesis adopts the overall to local and top-down design idea,first discusses the three-tier architecture of the system as a whole,including application service layer,network protocol layer and traffic access layer,then introduces the core implementation scheme of each layer in detail in chapters,and carries out simulation experiments on the key technical indicators.Firstly,starting from the design of Industrial Internet identification and resolution application service,this thesis first establishes an identification and resolution network based on distributed hash table at the application layer,designs a cross identification and resolution system analysis scheme,realizes the basic identifier life cycle management interface,and ensures the business requirements of the system design.Aiming at the security problem of identification and resolution application,this thesis introduces the zero trust security mechanism based on trust value calculation,which provides a reliable guarantee for the security of identifier data in the whole life cycle.Through simulation experiments,the security of identification and resolution under hierarchical trust mechanism is verified.Then,this thesis optimizes the underlying network protocol used by the designed distributed identification and resolution application layer service,realizes the UDP/IP user state protocol stack to support the two copies of TCP/IP network protocol stack and the user state kernel state switching problem,and designs IRP identification and resolution transmission protocol and Protobuf based serialization transmission scheme for identifier resolution packets,Simulation experiments show that the mechanism greatly improves the efficiency of data transmission.Finally,aiming at the identification and resolution system traffic accessed by the system,this thesis designs a unified traffic access layer,uses LVS to build a direct routing model from the identification and resolution client to the server,and designs a load balancing algorithm DQRB algorithm based on the dynamic quantification of the analysis load of the identification and resolution server,which realizes an efficient load balancing scheme,The performance verification and result analysis are carried out through simulation experiments,which demonstrates the high reliability,high performance and high security of the distributed identification and resolution system designed in this thesis.
