Research And Implementation Of New Convergence Network Communication Mechanism Based On Universal Identifier Network

The lack of considerations in terms of security,mobility,controllability,manageability of the existing Internet architecture design has resulted in frequent network security incidents,seriously jeopardizing public interest and national security.To this end,lots of future network architectures such as Information Center Networks(ICN)and Universal Identifier Network(UIN)have emerged in recent years.Among them,UIN provides mobility,security,and scalability via the Identifier Separating and Mapping Scheme,which can meet the requirements of security,manageability,controllability,and credibility.However,as a brand-new transformative network architecture,UIN lacks a network communication mechanism that can effectively integrate IPv4/IPv6.Therefore,this thesis proposes a new type of integrated network communication mechanism based on UIN,and designs a discrete variable Access Identifier(AID)and discrete variable Router Identifier(RID)mapping mechanism to achieve integration with existing IPv4/IPv6 networks.The main work of this thesis are shown as follows:(1)Propose a mapping mechanism between variable(Longer or shorter)AID and RID to support multiple types of address mapping.(2)Design a unified mapping and encapsulation/decapsulation method to realize the transformation of the data packet between TCP/IP and UIN to solve the interworking problem.(3)Propose a new AID design method which comsisits of a 32-bit or 128-bit as a prefix and a 16-bit port numbers,and it is compatible with the IP address format of the terminal and uniquely represents the network terminal.This method guarantees the uniqueness of the AID and allows user terminals mobility in traditional networks.(4)Design and implement a mapping and encapsulation function module,which can adapt to multiple network scenarios and perform different mapping and encapsulation.Design and implement the two-level mapping server partition scheme of total mapping server and regional mapping server.The allocation to the regional mapping server can be completed according to the regional location,providing efficient mapping relationship query and improving communication efficiency.Finally,this thesis tests and analyzes the transmission function,mobility and network communication performance of the new convergence network in various scenarios by building a test platform.The scheme has been proved correct by the experimental results.
