Abstract
Described are methods and system for network analysis. A network analyzer for a first network is configured to receive network assessment information from a network metric monitors situated in third-party networks, the network assessment information indicating values for characteristics of one or more network paths from the respective network metric monitor to a node in a second network. The network analyzer aggregates the received network assessment information and identifies, from the aggregated network assessment information, a route from the first network to the node in the second network. The identified route is then selected from among a plurality of potential routes from the first network to the node in the second network and used in setting a routing policy for data flows from the first network through the node in the second network.
