The minimum bandwidth required at each time slot of the fast broadcasting scheme

In this paper, we show that the Fast broadcasting scheme (L.-S. Juhn and L.-M. Tseng, 1998 [4]), abbreviated the FBR scheme, is also suitable for heterogeneous clients of different communication capabilities although it is originally designed for homogeneous clients of the same bandwidth. Given α   channels of total bandwidth α⋅b Mbpsα⋅b Mbps to deliver a video of the consumption rate b Mbpsb Mbps, we first show that the FBR scheme can be employed to serve clients with communication capabilities ranging from b   to α⋅bα⋅b Mbps. Furthermore, we propose a simple way to determine the minimum bandwidth required at any given time slot.

► Fast Broadcasting scheme (FBS) is a widely known approach.
► FBS can be applied to heterogeneous clients.
► The minimum bandwidth required at any given time slot can be determined.
