YouTube等用户生成内容(UGC)视频点播服务越来越受欢迎，其维护成本也在不断增长。在这类系统中，已经提出了许多P2P解决方案来降低服务器负载，但几乎所有的P2P解决方案都集中在单视频方法上，这种方法对UGC等短视频服务系统的影响有限。本文的目的是研究另一种方法--多视频方法的潜力，并使用一种非常简单的方法--协作缓存来说明使用多视频方法的方法通常更适合于当前的UGC视频点播系统。我们还通过仿真研究了主要设计因素的影响，为使用该方法高效地构建系统提供了指导。
User Generated Content (UGC) VoD services such as YouTube are becoming more and more popular, and their maintenance costs are growing as well. Many P2P solutions have been proposed to reduce server load in such systems, but almost all of them focus on the single-video approach, which only has limited effect on the systems serving short videos such as UGC. The purpose of this paper is to investigate the potential of an alternative approach, the multi-video approach, and we use a very simple method called collaborative caching to show that methods using the multi-video approach are generally more suitable for current UGC VoD systems. We also study the influence of the major design factors through simulations and provide guidelines for efficiently building systems with this method.
