Routing decisions between ASs are derived from reachability information exchanged via routing protocols (BGP) between these AS's, as well as local policies. The Routing Information Service (RIS) is a new project at the RIPE-NCC. The goal of the RIS is to collect time-stamped BGP updates from default-free border routers of many ASs, at topologically interesting network points. These updates will be stored in a database that can be queried interactively by the community.

The information stored in the RIS can be used, amongst other things, to understand network reachability from remote locations for tracing past routing problems, for reality checks of routing policies registered in the various Routing Registries, and for statistical analysis.

This presentation will introduce the RIS project and show some first results based on the first development version of this service.

More details are available from the RIS Web site.
