Performance study of multi-channel multicast delivery for scheduled videos

In reality, not all users require instant video access. People are used to planning 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 stream scheduling and resource utilization based on pricing. We provide a performance study of our proposed multi-channel multicast delivery (MCMD) scheduling algorithm for SVD. MCMD fully utilizes the multi-channel receiving capability of the clients to improve the resource utilization and the degree of multicast in delivering continuous media. The performance study of its scheduling behavior shows that MCMD produces lower rejection rate and requires fewer number of channels to have no rejections than the existing MEDF and LPF on SVD.
