As exterior routing protocols generally do not provide information about the internal routing paths of an autonomous system, a particular autonomous system has limited information about the internal health of other autonomous systems. However, if a monitoring system has access to routing data and/or other network data from multiple points of an autonomous system, the monitoring system can estimate, with some accuracy, the health of the autonomous system. In turn, by monitoring at least some of autonomous systems forming a larger internetwork, such as the Internet, the monitoring system can estimate the overall health of at least portions of the internetwork. |
