As an important type of distance education, an essential link in the application of e-learning, video-on-demand (VOD) technology meet the requirement of multimedia source by learners. In the paper, by using the technical advantage of grid technology, we put forward a better solution for traditional single VOD server which is easy to cause a bottleneck in processor performance and storage capacity and so on, and present an integrated approach of multi-VOD server with grid technology. This proposition will benefit learners in pursuit of knowledge undoubtedly in the future.
