中文摘要：
提出一种云计算与对等计算融合模型Cloud—P2P，并基于Cloud—P2P构建一种新颖的泛知识云系统，将网络中的各类文献、知识信息有序地组织在一起；充分考虑网络边缘节点上可以利用的资源，在保障用户使用体验的前提下，将用户提交的知识索取任务从网络中心的服务器端迁移到网络边缘的客户端。为进一步改善用户的使用体验，提出一种动态的复合自适应QoS保障机制，通过综合区分用户与资源类型，并设定服务器负载阈值，解决传统知识系统中存在的高峰阶段服务器性能瓶颈的难题，从而达到提高系统中用户整体普遍满意度的目标。
英文摘要：
Abstract： This paper presented a novel ubiquitous knowledge cloud model based on Cloud-P2P network platform, which or- ganized the various types of documents, knowledge orderly together, and took full account of the available resources of network edge. In the premise of protecting user＇s experience, the model made the tasks about knowledge requirement submitted from users migrate from the network servers to the nodes of network edge. To further improve the users＇ satisfaction, it proposed a new dynamic complex adaptive quality of service protection mechanism, which provided an effective solution of the problem of server performance bottleneck in peak time existing in the traditional knowledge systems through differentiating the different types of users and setting the threshold of server load.
