Traditional system based on the current form of distance education network technology does not support the existence of dynamic multimedia data and real-time streaming data, as well as the existence of streaming media technology in the server bottleneck problem. The key technologies of streaming media digital resources transmission based on CDN (Content Delivery Network) and P2P (peer-to-peer) is discussed in the paper, and the P2P core algorithm is optimized, the CDN network deployment of the program and the edge server deployment strategies are discussed, which can address the situation of network congestion and improve user access to video and web site response time.
