CAIDA UCSD AS Rank

AS Rank is CAIDA's ranking of Autonomous Systems (AS) (which approximately map to Internet Service Providers) and organizations (Orgs) (which are a collection of one or more ASes). This ranking is derived from topological data collected by CAIDA's Archipelago Measurement Infrastructure and Border Gateway Protocol (BGP) routing data collected by the Route Views Project and RIPE NCC. ASes and Orgs are ranked by their customer cone size, which is the number of their direct and indirect customers.

AS排名（AS Rank）是CAIDA针对自治系统（Autonomous System, AS，大致对应互联网服务提供商）以及组织（Organization, Org，即由一个或多个自治系统组成的集合）推出的排名体系。该排名依托CAIDA群岛测量基础设施采集的拓扑数据，以及路由视图项目（Route Views Project）与RIPE NCC采集的边界网关协议（Border Gateway Protocol, BGP）路由数据生成。自治系统与组织的排名依据其客户锥规模确定，客户锥规模指其直接与间接客户的总数量。
