最近，对等（P2P）配置在互联网社区中引起了相当大的兴趣。同时，P2P经常因其糟糕的扩展行为而受到批评。我们分析P2P信令流量，无论是通过分析估计，并通过计算机模拟。借助两种概率方法，我们可以根据例如Gnutella协议中给出的纯对等协议导出P2P信令业务增长的上限和下限。在模拟的帮助下，我们能够验证我们的数学推导。因此，P2P实际上比依赖于简化假设的更传统的理论所预测的要好得多，因此不能假设纯对等网络中的消息传递负载呈指数增长。
Recently peer-to-peer (P2P) configurations have found considerable interest in the Internet community. At the same time P2P has often been criticized for poor scaling behavior. We analyze P2P signaling traffic, both via analytic estimates and via computer simulation. With the help of two probabilistic approaches, we can derive an upper as well as a lower bound for the growth of P2P-signaling traffic, according to a pure peer-to-peer protocol as given e.g. in the Gnutella protocol. With the help of a simulation we are able to verify our mathematical derivations. As a result it appears, that P2P actually scales much better than predicted by more conventional theory relying on simplifying assumptions, and thus exponential growth of the messaging load in pure peer-to-peer networks must not be assumed.
