Advances in computing and networking are generating a significant demand for video-on-demand (VOD) applications. In this paper, the condition for minimum blocking probability of a VOD system is derived. The optimal load-sharing requirement in such a system is found so that the minimum blocking probability is achieved. A combination of genetic algorithm and modified bin-packing algorithm is then developed for the multimedia file placement exercise. It is demonstrated that a specified blocking probability can be achieved while the capacity usage is minimized simultaneously
