Design And Implementation Of Multi-Dimensional Unified Identifier Mechanism

Facing the continuous expansion of Internet application services,the thin waist structure of the traditional TCP/IP network has problems of poor support ability in terms of mobility,security,and quality of service.In recent years,to solve the existing defects of the IP network,the research on future network architecture has continuously explored the network capabilities using different types of network entities.They are improving the network’s ability to support services in all directions.The identifier naming and its system framework are the important base stones to support the network’s working.It is important to design scientific and rational identifier naming and network system framework.However,the current future network identifier and architecture have fundamental problems such as single identity bearer,difficulty in suppressing unknown threats,and unable to make full use of network information.It is also difficult to realize real-time network location awareness in mobile scenarios,accurate services for complex user needs,and network endogenous security support.To solve the above problems,this thesis proposes a unified multi-dimensional identifier naming method that supports various network entities such as equipment,content,services,and specific groups.We also build a multi-dimensional identifier system framework.The specific contributions of this thesis are as follows.Firstly,based on the analysis of the existing network identifier and system architecture,this thesis clarifies the identity design requirements based on multidimensional attributes.And,a multi-dimensional identifier naming scheme that unifies various network entities is proposed based on the principle of identity location separation.A multi-dimensional unified identification system framework is constructed,including the service layer,the interface layer,and the network layer.Secondly,the network functions are split by layered decoupling.The service layer multi-dimensional attribute analysis mechanism and security authentication mechanism are proposed.The network service interface adapting to multi-dimensional identification is constructed.And,the network layer interaction protocol and communication process are designed.Thirdly,combined with the object-oriented idea,a multi-dimensional unified identifier client based on Java is realized,which realizes the attribute analysis,security authentication,and data transmission functions suitable for the Multi-dimensional Identifier Network.Based on the new network paradigm of SDN and the P4 programmable language,we realized the data forwarding and routing of the network layer.Finally,a prototype experimental system of the multi-dimensional unified identifier system is built,and we tested the communication and security functions experimentally in typical scenarios.The experimental results show that the multi-dimensional identifier system can support complex user needs under a variety of network objects.The selfauthentication design of identifiers can help efficient network and terminal identity authentication to realize.And,it makes the network more safety.
