Embodiment Construction
[0029] The technical solution of the present invention will be further introduced below in conjunction with the accompanying drawings.
[0030] The implementation steps of the video-on-demand system based on the GoogleAppEngine cloud platform are as follows: the overall system architecture is divided into three parts: the cloud computing distributed basic platform (1), the video distribution service module (2) and the video-on-demand application software module (3). The system architecture is as follows: figure 1 shown.
[0031] 1. Cloud Computing Distributed Basic Platform
[0032]The cloud computing distributed basic platform (1) includes a GoogleAppEngine cloud platform (11) and a video-on-demand streaming media server cluster (12), and the web container is an efficient JavaServlet container Jetty, which can run websites, web services, and the like. The Google AppEngine cloud platform (11) further includes an AppEngine Web container (111) and several server nodes (112), an...

The invention provides a video-on-demand system based on a Google App Engine Cloud platform, belongs to internet application, and aims at designing and completing a high-performance distributed type system level scheme capable of meeting real-time video-on-demand requirements of large numbers of users. By means of the design of the video-on-demand system on the Google App Engine Cloud platform, what users face is not a pure video website, but a video data transmission network composed of distributed type server groups. A large number of videos are stored in distributed type server nodes with different performance according to strategies such as video-on-demand popularity and similarity, video contents are distributed on the condition that the fact that a plurality of data are redundant is guaranteed, and video service nodes are dynamically distributed according to the number of real-time video-on-demand requests of the users. Therefore, dynamic video-on-demand requirements of the internet users can be met, video-on-demand quality can be improved, and user experience is enhanced.
Description
technical field [0001] The technology of the present invention belongs to an Internet application. Background technique [0002] In recent years, with the rapid development of multimedia technology and network technology, the types and quantities of Internet applications have continued to grow, and video-on-demand has become one of the mainstream Internet applications such as email, instant messaging, and social networking. However, with the rapid increase of Internet users, more than 400 million people have become users of video websites in my country. People's demand for online video is increasing day by day, and the update speed of video is constantly accelerating. For the huge amount of program video data, its storage, transmission, and a large number of concurrent access issues all pose new challenges to the software and hardware of online video on demand. , and the expansion of the entire video-on-demand system is complicated and the maintenance cost is high, so new t...
