CAIDA UCSD AS Facilities Mapping (2017-03-01 to 2017-04-30)

Interconnection facilities host routers of many different networks and partner with Internet Exchange Points to support different types of interconnection between the networks. This dataset contains detailed information about individual interconnection facilities including their names, operators, and geographic data; mapping of ASes to interconnection facilities; and types of peering interconnections used at those facilities. This data augments topological maps of AS connectivity with physical attributes and can be used to assess the resilience of interconnections in the event of natural disasters, identify facility or router outages, shed light on peering disputes, and help locate points of attacks, congestion, or instability on the Internet.

互联设施（Interconnection Facilities）承载多个不同网络的路由器，并与互联网交换点（Internet Exchange Point，IXP）合作，以支持网络间的多种互联模式。本数据集收录了各互联设施的详细信息，包括其名称、运营主体与地理数据；自治系统（Autonomous System，AS）与互联设施的映射关系；以及这些设施所采用的对等互联类型。该数据集通过物理属性补充了自治系统连通性拓扑图，可用于评估自然灾害等场景下互联链路的韧性、识别设施或路由器中断状况、厘清对等互联纠纷，以及协助定位互联网上的攻击、拥塞或不稳定节点。如需了解方法论与数据格式的详细说明，请访问：http://www.caida.org/data/as-facilities/
