Abstract


The rapid development of Internet technology, to make human life took a revolutionary change. However, with the rapid expansion of network size, network services and constantly enrich the traditional network architecture is facing unprecedented pressures and challenges. Increasing complexity of network management, network inefficiency, it is difficult to meet the demand for the development of quality of service. Explore implement new network architecture is a fundamental solution to this problem solutions related research work unfolds gradually. Autonomous network is a new network architecture is an important research direction. Network of ideological autonomy thanks to autonomic computing, autonomous communications research, in the design of network architecture to achieve self-organization, self-management, self-configuration, self-perception, self-optimizing, self-protection, self-healing features such as autonomy, seeking to improve networks and services, to deal with the unknown changes, such as topology, load, business needs, network physical characteristics. Characteristics through the realization of having autonomous network architecture to simplify the management of complex communication structure, reducing the need for human intervention. Autonomous development of the network independent of the end user applications and services needed, with a service-driven, self-organization, distributed, scalable characteristics, is an important trend in network development. Autonomous network routing services is to achieve self-government basis, this paper is a national 863 Project \technology - autonomous routing protocol carried out research. This paper first introduces the relevant background autonomous networks, network architecture, and describes the CAANM designed CAANM routing framework. According to the idea of ??autonomous networks, this paper studies CAANM autonomous routing protocol routing framework designed by summing routing technology development, analysis of autonomous routing protocol research. Then learn QoS routing ideas, research-based context-aware autonomous routing protocol. Based on the QOSPF protocol simulation, this paper proposes a multi-type of QoS routing protocol MQOSPF, extends the traditional QoS routing using context information, regardless of network BE traffic state. The simulation results show that, MQOSPF agreement enhances QOSPF autonomous features to improve network performance. Finally, this paper summarizes the main work and pointed out the shortcomings and further possible research directions.
