E-learning System Based On P2p Network Environment Analysis

In the past several years, there has been a rush of Internet-based educational platforms and services. E-Learning has been applied widely and it is developing rapidly in China. At the same time, the Chinese government has made the standards which will be used to standardize how to make e-Learning resources. Whereas, there are lots of problems confronted with e-Learning. Problems that e-Learning resources can not be distributed and shared and that e-Learning resources are not located properly are most severe.This paper introduced the actuality of e-Learning first. Against the confronted problems, it brought forward a new e-Learning platform named P2POES using the latest information technology. This platform is based on P2P network, and the e-Learning resources which are located on P2POES are encapsulated into Web Service. This paper described the P2POES architecture, and it introduced how P2POES was composed. It also made out the P2POES protocol suit. At last, it researched how to describe e-Learning resources using the Chinese standards & WSDL and how to search the resources by parsing the description. And, it also introduced how the P2POES message was made of and the procedure the message was encapsulated.
