Design Of Autonomic QoS System Based On Service-Aware

The traditional architecture of the Internet can not meet the development of networking application in many aspects. The study on the architecture of autonomic network is the hot spot of current studies on network architecture. Autonomic network is a novel network with good scalability, dynamicity and security, which is able to produce various policies on the operations of the whole network and nodes autonomic. Autonomic netwrk can satisfy the development requirements of future network. The future network should be able to provide diversity QoS assurance, and also be able to meet the dynamic change of network environment to satisify the special needs of different users. At the same time, the multi-service nature of future network requires to bring in the sevice-aware technologies to improve the traditional QoS mechanisms. How to provide QoS in future autonomic network is the hot spot of current studies.This thesis which is the sub-project of National 863 project "Context-Awared based Autonomic Network Model and architecture research" (CAANM), studies the design and implementation of autonomic QoS system in autonomic network. Standing on the GANA 4D/A4D architecture, we designed the CAANM QoS system based on the autonomic control loop. On this basis, we analyzed the current IP QoS models and improved them by bringing in service-aware technologies. Here we designed an autonomic QoS system based on service-aware and explored its implementation way.In the thesis, the related background technologies were specified firstly. These technologies included the research status on autonomic network, IP QoS technologies, IPv6 technologies and service-aware technologies. Then the technology scheme in CAANM project was described. And then we introduced the design of autonomic control loop in CAANM project. We introduced the design of CAANM QoS system from Network, Node, Function and Protocol these four levels. Here we put emphasis on the design of service-aware function and queue scheduling function. Also we described the design of autonomic QoS system based on service-aware, including requirement analyse, summary design and detailed design, also the implementation methods is mentioned.In the end of this thesis, we give the summary of the whole thesis, point out the lacking of work, and make the forecast of the future research direction.
