Looking for Network Latency Clusters in the LAC Region.

Measuring Internet connectivity is complex and represents a major challenge. Successful connectivity measurement requires access to a large number of probes, distributed across the monitored networks, as well as a large number of measurements to capture as much intra- and inter-network information as possible. In this paper we present an approach to measure ICMP connectivity based on RTT measurements, performed on a distributed active measurement platform. Based on these measurements, we study the intra-country and inter-country network connectivity within the Latin America and Caribbean (LAC) region. By relying on clustering algorithms, we unveil LAC sub-regions showing better connectivity patterns, and identify regions with poor connectivity. The presented techniques and results are not only highly useful to improve network management and content location in the LAC region, but also to advance the Internet connectivity among LAC countries.
