We investigated Internet eXchange Points (IXPs) deployed across Latin America. We discovered that many Latin American states have been actively involved in the development of their IXPs. We further found a correlation between the success of a national IXP and the absence of local monopolistic ASes that concentrate the country's IPv4 address space. In particular, three IXPs have been able to gain local traction: IX.br-SP, CABASE-BUE and PIT Chile-SCL. We further compared these larger IXPs with others outside Latin America. We found that, in developing regions, IXPs have had a similar growth in the last years and are mainly populated by regional ASes. The latter point clearly contrasts with more internationally re-known European IXPs whose members span multiple regions.

拉丁美洲 IXP 初探

我们调查了拉丁美洲部署的互联网交换点 (IXP)。我们发现许多拉丁美洲国家一直在积极参与其 IXP 的开发。我们进一步发现，国家 IXP 的成功与缺乏集中该国 IPv4 地址空间的本地垄断 AS 之间存在相关性。特别是，三个 IXP 已经能够获得本地牵引力：IX.br-SP、CABASE-BUE 和 PIT Chile-SCL。我们进一步将这些较大的 IXP 与拉丁美洲以外的其他 IXP 进行了比较。我们发现，在发展中地区，IXP 在过去几年中也有类似的增长，并且主要由区域 AS 组成。后一点与更多国际知名的欧洲 IXP 形成鲜明对比，这些 IXP 的成员跨越多个地区。
