本文提出了一种测量研究的拓扑结构及其对使用Guifi.net，一个大规模的社区网络的影响。它侧重于社区网络面临的主要问题和教训，以考虑其未来的增长，以保持其可扩展性，稳定性和开放性。结果表明，该网络拓扑结构是一个典型的高密度无标度网络，具有临界故障点和不良的网关选择或放置。此外，我们还发现了具有大量跳数的路径，即图的大直径，特别是叶节点和Web代理之间的长路径。使用广泛的Web代理服务的使用分析证实，这些拓扑属性对用户体验的影响。
This paper presents a measurement study of the topology and its effect on usage of Guifi.net, a large-scale community network. It focuses on the main issues faced by community network and lessons to consider for its future growth in order to preserve its scalability, stability and openness. The results show the network topology as an a typical high density Scale-Free network with critical points of failure and poor gateway selection or placement. In addition we have found paths with a large number of hops i.e. large diameter of the graph, and specifically long paths between leaf nodes and web proxies. The usage analysis using a widespread web proxy service confirms that these topological properties have an impact on the user experience.
