Facebook是当今最受欢迎的社交网络，在全球拥有超过10亿用户。为了提供良好的服务质量（例如，FB依赖Akamai，Akamai提供全球内容分发网络，并拥有大量边缘服务器，这些服务器距离FB用户更近。在本文中，我们旨在描述当前FB网络基础设施部署的全局情况，同时考虑本地FB服务器和Akamai节点。为此，我们在两周内使用分布在41个国家/地区的463个Planet- Lab节点进行了基于测量的分析。根据获得的数据，我们比较了不同国家/地区的节点访问本地FB服务器和Akamai节点时的平均访问延迟。此外，我们还广泛了解了Akamai节点的部署情况，这些节点为全球FB用户提供服务。最后，我们分析了这些节点的地理覆盖范围，并证明在大多数情况下，位于特定国家/地区的Akamai节点不仅为当地FB用户提供服务，还为位于附近国家/地区的FB用户提供服务。
Facebook is today the most popular social network with more than one billion subscribers worldwide. To provide good quality of service (e.g., low access delay) to their clients, FB relies on Akamai, which provides a worldwide content distribution network with a large number of edge servers that are much closer to FB subscribers. In this article we aim to depict a global picture of the current FB network infrastructure deployment taking into account both native FB servers and Akamai nodes. Toward this end, we have performed a measurement-based analysis during a period of two weeks using 463 Planet- Lab nodes distributed across 41 countries. Based on the obtained data we compare the average access delay that nodes in different countries experience accessing both native FB servers and Akamai nodes. In addition, we obtain a wide view of the deployment of Akamai nodes serving FB users worldwide. Finally, we analyze the geographical coverage of those nodes, and demonstrate that in most of the cases Akamai nodes located in a particular country service not only local FB subscribers, but also FB users located in nearby countries.
