Research On The Key Techonologies Of Distributed Policy Management System

With the fast development of computer networking and communication technology,the network's scale becomes larger,the management of the network becomes harder.PBMA(policy based network management)is one of the most promising technologies in the realm of network management research.According to different network states,network management system adopts different management strategies,which improving the network management and the network's adaptability.The common problem of traditional policy management systems,such as IETF strategy management system framework and Ponder strategy deployment framework is that it needs the administrator to manually modify the strategy,which is always after the changes of the network environment.On the other hand,it is necessary and important to improve the current policy management system's survivability.In view of the above problems,this thesis studies distributed policy management system's key technologies,proposes a distributed policy management system's agent framework,and a communication agent technology is proposed to improve the policy management system's survivability,Finally,a distributed computing job scheduling framework based on Hadoop is developed to handle the distributed policy management system's massive computing job,all the research results are developed and fully tested,which is one of the most popular cloud computing platforms.
