Method for ensuring quality of service of knowledge system based on cloud computing technology

The invention provides a method for ensuring the quality of service of a knowledge system based on a cloud computing technology. A cloud computing model is a wider public virtual resource pool composed of a server cluster and a network edge node. The knowledge system capable of putting documents and knowledge information of all kinds in a network together in order and taking usable resources on the network edge node into full consideration is built on a platform. In order to improve a user experience, the method for ensuring the quality of service of the knowledge system based on the cloud computing technology ensures that users in different grades can obtain different qualities of service under the condition of limited resources. The method for ensuring the quality of service provided by the invention schedules different service requests from different users to different nodes dynamically by distinguishing the types of the users and the resources in the knowledge system based on the cloud computing technology comprehensively and setting a threshold value of a server load.
