On utilizing multi-channel to provide scheduled video delivery
نویسندگان
چکیده
In reality, not all users require instant video access. People are used to plan things ahead, surely including when to watch desired videos. This fact creates the new video scheduling paradigm, named Scheduled Video Delivery (SVD). It allures clients to make requests as early as possible in order to increase the flexibility of scheduling and resource utilization based on pricing. In this paper, we propose the Multi-Channel Multicast Delivery (MCMD) scheduling algorithm for SVD. MCMD fully utilizes the multi-channel receiving capability of clients to improve the resource utilization and the degree of multicast in delivering continuous media. The case study of scheduling behavior shows that MCMD produces lower rejection rate, higher channel utilization, and shorter delivery time than the existing MEDF and LPF on SVD.
