| As the current Internet users and network applications has been expanding continuously extends,increasing demand of Internet service,but at this stage of network has been unable to keep up with demand,various problems appear constantly.Thus the concept of next generation network update is also increasing,our country also need to develop a set of with independent property rights of new network,to alleviate the network problems,enhance ability of management and service network.To meet the requirements of future network construction,research on multi-dimensional signage structure model and design principle and method,addressing realization method based on multi-dimensional signage system and simulation verification of multi-dimensional signage system mechanism were carried out.In this thesis,the need for a multidimensional identity structure model and the design principle and method of research.Firstly,the principle and method of multi-dimensional identification system design of the object,connection and application of network elements are studied,and the unified representation and description method of the uniqueness,certainty,completeness,usefulness,timeliness and traceability of the identification of the object of network connection is studied.A new multi-dimensional identification architecture is designed and a multi-dimensional identification architecture model is constructed.The complex correspondence between multidimensional identification and network knowledge system is studied to support the link of knowledge.Research on identity enhancement theory for secure and trusted user behavior data modeling requirements,identity security design requirements,traceability technology;Study multi-dimensional identification system running mechanism,support mobility,security,and diversified intelligent routing addressing mechanism and methods.Secondly,the addressing implementation method based on multidimensional identification system is studied.A multi-dimensional identifiers oriented routing addressing mechanism is proposed,which supports designated identity addressing,service addressing,geographic location addressing,attribute addressing,multicast addressing,combined addressing,etc.,taking into account multi-dimensional service functions and routing forwarding efficiency.In order to meet the needs of identity and network security,a multi-dimensional identification based fine-grained secure access authentication and traceability implementation method is proposed.A simple,efficient,accurate,secure and flexible routing policy and forwarding mechanism can be designed to address and forward network objects in the optimal way as required to meet the diversified service requirements of users.In this thesis,two planes are used to assist the construction of identification network.The control plane designs common unicast,multicast,and network addressing routing mode based on geographic location,content oriented and by delay problem.Through multi-dimensional identification based addressing routing decision module,the optimal and most suitable routing protocol can be delivered dynamically in various application scenarios.The corresponding addressing routing application is delivered to the ONOS control core,which generates the corresponding flow table and delivers it to the intra-domain agent.The proposed unicast addressing is based on device object identification or network connection identification,which can support availability in delay-tolerant scenarios.Multicast addressing is based on spatiotemporal unified identification or network connection identification to achieve group communication scenarios.Content oriented addressing is based on the application service identification,puzzled precipitation multidimensional identity.At the same time,the key technology of building the system model was verified,and the design simulation verification was carried out for multidimensional identification network,and the key transmission indicators of the model were detected to obtain the validity of the model. |
