Description of the Service

BGPath is an on-line service that helps understanding BGP updates.

The service relies on BGP RIB dumps and updates collected by the Routing Information Service and the Route Views Project in the week from 12/26/2006 to 01/02/2007.

BGPath features a stream-based back-end system, which

Collects data from many monitors,
Performs data cleaning processes that cope with both long-lasting unreliabilities of data sources and short-lived dirty data bursts,
Computes metrics over input data within strict time constraints.

BGPath also provides a user with an effective graphical interface that, given a routing change c:

Places the ASes involved in c according to the customer-provider hierarchy of the ISPs,
Visualizes both aggregated and disaggregated information for each interdomain link appearing in c,
Traces different paths to the prefix involved in c over time.

The service is integrated with software imported from the graphical interface of BGPlay.

As an additional function, BGPath also allows to perform comparisons of observed routing data against routing policies stored inside the Internet Routing Registry. The displayed registry information is retrieved and processed by the same engine used in the RPSL Analysis Service.
