Route collectors are extremely valuable to discover information about the Internet inter-domain ecosystem. However, the potential usage of data collected is limited by the small amount of ASes sharing their routing information and the nature of these ASes, typically provider independent and/or worldwide ISPs. We believe that one of the main reasons is that most AS administrators do not find any us
eful outcome in sharing their data and participating in any of these projects. The Isolario project (IIT-CNR) tries to introduce an additional motivation to attract even more ASes in participating in a route collecting project, thus increasing the amount of public routing information. To do that Isolario enhances the classic concept of BGP route collector introducing a set of real-time services built on top of the incoming BGP flows which are available only to administrators that decide to join the project, following the classic principle of reciprocity.
