在本文中，我们评估的内容分发服务的可靠性和效率方面的性能。所考虑的用于实现这种服务的技术可以是传统的客户端/服务器（CS）架构或对等（P2P）网络。在CS中，服务器的容量是瓶颈，并且必须以可以在任何时间容纳所有请求的方式来确定尺寸，而P2P系统不会给单个服务器带来负担，因为内容在网络中分布在共享对等体之间。然而，损坏或伪造的文件可能会降低P2P服务的可靠性，由于下载无用的内容。我们比较了CS系统的P2P和评估的下载时间，成功率和公平性，同时考虑闪光人群到达和损坏的内容。
In this paper we evaluate the performance of a content distribution service with respect to reliability and efficiency. The considered technology for realizing such a service can either be a traditional client/server (CS) architecture or a peer-to-peer (P2P) network. In CS, the capacity of the server is the bottleneck and has to be dimensioned in such a way that all requests can be accommodated at any time, while a P2P system does not burden a single server since the content is distributed in the network among sharing peers. However, corrupted or fake files may diminish the reliability of the P2P service due to downloading of useless contents. We compare a CS system to P2P and evaluate the downloading time, success ratio, and fairness while considering flash crowd arrivals and corrupted contents.
