为了解决视频点播系统中的可伸缩性问题，迄今为止已经提出了许多广播方案。该广播方案的主要性能参数是服务器广播带宽、用户带宽和用户初始等待时间。目前已知的对服务器带宽要求最低的广播方案对用户端的带宽要求与服务器端的带宽要求相同。我们提出了一种新的广播方案，称为广义斐波那契广播（GFB），以解决限制用户端带宽需求的问题。对于任意给定的服务器和用户带宽组合，在所有已知的广播方案中，GFB总能获得最少的用户等待时间。此外，它将非常容易实现GFB。
To address the scalability issue in video-on-demand systems, many broadcasting schemes have been proposed to date. The major performance parameters of such a broadcasting scheme are the server broadcast bandwidth, the user bandwidth and the user’s initial waiting time. The broadcasting schemes with the least server bandwidth requirement currently known require the same bandwidth on the user side as that on the server side. We propose a new broadcast scheme, named Generalized Fibonacci Broadcasting (GFB), to address the issue of limiting the user-side bandwidth requirement. For any given combination of the server and user bandwidths, GFB can always achieve the least user waiting time among all the currently known broadcasting schemes. Furthermore, it would be very easy to implement GFB.
