Abstract


The paper proposed the research on rural online distance education (RODE) based on the Beijing rural network condition, which aimed at helping farmers to get agricultural technology more effectively and sufficiently. This is the first platform that was applied to large-scale rural distance education, which combined with peer to peer (P2P) and content delivery network (CDN). What’s more, it initiates network video transmission into the RODE platform, which could save 80% of the bandwidth. In addition, MD5 encryption algorithm, content pre-reading technology and data logic chip technology were used to ensure the security of video data. It has the following advantages: easily deployed, highly scalable and low-cost.
