摘要
在分析各种P2P网络特点的基础上,提出了分布式环境中基于超节点的P2P e-Learning模型。对特定peer组中超节点的加入和超节点的服务进行了具体描述。针对e-Learning的特性,给出了模型中的数据抽象和本体描述,并对该P2P网络模型在文件传输方面的性能做了分析。
Compared with different structure of P2P network,a new P2P e-Learning model based on Super Peer in distributed environment is presented.How a super peer is joined and what the service is of a super peer are described in this paper,as well as a detailed description of the data Ontology and Metadata of the e-Learning model.lt also discusses the efficiency of the e- Learning model on file transfer issue.
