Knowledge Aggregation Under Network Environment-Sharing Platform Construction

As the quick development of computer network technologies and the digital technologies , Web-based education has entered a stage of digital , intellectualized , and customized development, the new commutation technologies provide more approaches for transmitting the latest education information and knowledge , and great break through has been made in construction of Web-based education resource . In recent years , people's demands on multiple media information are continuously increasing , Therefore , the streaming media technology of "synchronously download and play " emerged as the times require , and has developed quickly . The streaming media technology has solved the problem of transmitting multi-media resource , mostly video and audio information , in media or low band width networks . Learners are no longer made in time, geographical restrictions, truly real-time online collaboration with teachers and interaction . The high band width required by live streaming video greatly limits number of clients that connect to media server . This makes a lot of inconvenience on a high degree of shared Web-based education resource , and it is becoming a bottleneck to share Web-based educational resources . This paper sets up streaming media server based on peer-to-peer technique to increase the number of concurrent nodes . The purpose of this paper is devoted to doing researches on sharing platform of Web-based education resource based on peer-to-peer and streaming media technology , and truly achieves a high degree of shared Web-based education resource.This paper first briefly describes the construction and share quo of Web-based education resources . And then introduces the definition of streaming media technology , the operational principle of stream transmission , and the characteristics and advantages of streaming media . And then introduces the status quo of the peer-to-peer technology include its definition, classification , arithmetic of searching and the internet applications . Through the analysis of the purposes of functions , framework and key technology , the paper designs are solution of shared platform of Web-based education resource based on peer-to-peer and streaming media server , and expatiate the system's significance and foreground.
