On a mid-1990s, since the development of IPv6 protocol, IPv6 international widely regarded as synonymous with the Next Generation Internet (Next Generation Internet, NGI). Four challenges because it followed the existing Internet architecture, can not be a fundamental solution to the the Internet facing high-speed exchange, service quality assurance, safe, reliable and easy to manage, as well as mobility. Public until 2006, the global network of innovation environment (Global Environment for Network Innovations, GENI) showed that \In after, academia and industry in order to gradually shift from the stance of IPv6 is NGI over. However, so far, in the \Southwest Jiaotong University \Taking into account the future backbone communication subnet will DWDM as the representative of the optical communication technology based, while the access to the communication technology will include a wireless communication technology, including a variety of techniques coexist reality, it is difficult as the OSI / RM as envisaged. All networks are unified hierarchy. Therefore, the laboratory \2003 laboratory 3D Ethernet MAN architecture framework, and in 2004 changed its name to the \network architecture. SUPA's R \u0026 D target is to build high-speed, high efficiency, security and quality of service can be guaranteed core backbone communications subnet. SUPA full use of the \monolayer structure. SUPA U-platform user data \As the backbone network, the SUPA the U-platform through its safe, multi-granularity tunnel services (Tunneling) the external access network (Internet Ethernet or wireless network) of user data (frame, packet, or other form of data) to be encapsulated and transmission. This paper reflects the work the laboratory pre SUPA framework, in particular, on the basis of service quality assurance framework, further study and perfect the SUPA multi-granularity service quality control mechanisms, and Internet and wireless heterogeneous network as SUPANET access to study the quality of its service network, can protect the premise under the mobility management technique. The main research work includes: (1) for the problem of how to support multi-granularity QoS SUPANET original mechanism first analyzes the QoS guarantee mechanism SUPANET oriented virtual channel, and on this basis, the definition of a fine-grained virtual channel (Fine Granularity Virtual Tunnel, FGVT), the average data rate protection the coarse grained virtual channel (Average Datarate Guaranteed CGVT, ADG-CGVT) and do my best coarse-grained virtual channel (Best Effort CGVT BE-CGVT), to form a multi-granularity virtual channel (Multi-Granular Vitrual Tunnel, MGVT) mechanism. Then studied business flow mapping mechanism, defined the business flow MGVT mapping rules; proposed a resource adaptive algorithm CGVT, simulation results show that the the resource adaptive algorithm can effectively improve the resource utilization. Finally, in the multi-granularity virtual channel mechanism business flow mapping mechanism, as well as a virtual channel resources adaptive mechanism based on the proposed multi-granularity based on SUPANET the QoS control framework model. Granularity QoS control mechanism based on SUPANET multi how to solve SUPANET Internet connectivity (2) the mobility management problem, the first analysis of the virtual channel switching problems exist in the environment, were designed FGVT, ADG-CGVT well The BE-CGVT switching mode, and in switching mode FGVT study proposed reconstruction of the virtual channel (the Virtual Tunnel Rebuilding VTR), virtual channel extension (Virtual Tunnel Extension, VTE) and expanded first built after (Extension First Rebuilding Second, EFRS) virtual channel switching mode, the simulation results show that the EFRS the outperforms VTR and VTE. Finally, in MIPv6, FMIP as well as SIP-based mobility management scheme on the basis of the analysis, were studied MIPv6, FMIP and SIP mobility scheme, the switching mode and the virtual channel of the above three fusion mechanism. (3) how granularity QoS control mechanism based on SUPANET multi-network selection problem solve SUPANET heterogeneous wireless network interconnection, using AHP (Analytic Hierarchy Process, AHP) right to the QoS of the 3GPP business category gravimetric analysis designed based on the business category distinction weighted networks choose algorithm for (Differentiation Weighted Network the Selection Algorithm DWNSA), simulation experiments verify, DWNSA compared with the average weight algorithm can in protection business QoS requirements premise, effectively to balance the load on the candidate network. Then, a virtual channel resources based network selection algorithm (Resource of of Virtual Tunnel based DWNSA RVT-DWNSA), and define the parameters of the algorithm in multi-granularity virtual channel, by simulation experiments the RVT-DWNSA the effective sex. (4) Finally, on the basis of analysis of next generation network mobility management framework defined in ITU-T model, the proposed QoS control mechanism SUPANET multi-granularity mobility management framework model, defines the position based on the framework of the model management function module and switch control function modules, the design of multi-granularity QoS control mechanism of end-to-end seamless handover process. This research work to fill the blank SUPANET in multi-granularity QoS control and mobility management research is an important part of the improve SUPANET framework, and provide a strong support for SUPANET as a next-generation network backbone network research.
