基于P2P网络的多校区分布式教学资源共享模型

Multi-campus Distributed Teaching Resource Sharing Model Based on P2P Network

为了有效整合、利用多校区分布式教学资源,基于P2P网络设计了多校区分布式教学资源共享模型。通过教学资源集合的特定属性构建域,搜索分布式教学资源,凭借关联度和Jaccard相似度集成教学资源。基于此,设定访问控制模式,并加密资源的初始版本,根据边缘节点域、服务器域构建P2P网络下的共享模型。在模型内添加全局节点信息管理、全局资源信息、检索模块、集中管理的分布式教学资源库模块,从而实现资源的可靠共享。实验结果证明:该模型在分布式资源共享中有着共享速度快、资源更新及时的优点。

In order to effectively integrate and utilize the multi-campus distributed teaching resources,a sharing model of multi-campus distributed teaching resources was designed based on P2P network.The domain is constructed by the specific attributes of the teaching resource set,then the distributed teaching resources are searched,and the teaching resources are integrated by the correlation degree and Jaccard similarity degree.Based on this,the access control mode is set,the initial version of the resource is encrypted,and the sharing model under P2P network is built according to the edge node domain and server domain.Global node information management,global resource information,retrieval module and centrally managed distributed teaching resource database module are added into the model to realize the reliable sharing of resources.The experimental results show that this model has the advantages of fast sharing speed and timely updating of resources in distributed resource sharing.
