Abstract
In video-on-demand (VoD) services, the clients such as smartphones and laptop computers request video data to the video distribution servers. The load on the video distribution servers increases as the number of the clients increases. Thus, the video interruption time lengthens. For this reason, large scale VoD systems use edge computing technology to distribute the load of the video distribution servers. Edge-Assisted VoD systems [7] distribute these loads by enabling the edge servers to receive the pieces of video data in advance of the clients’ requests (pre-cache). In this research, we propose pre-cache methods for edge-assisted VoD services aiming to accommodate more clients. Our evaluation results revealed that our proposed methods reduce the communication load of the video distribution server and accommodate more clients by up to 14% compared to an existing method.
