NANOG Meeting Presentation Abstract

The BGP Visibility Scanner
Meeting:	NANOG57
Date / Time:	2013-02-06 12:00pm - 12:30pm
Room:	Crystal Ballroom A-C
Presenters:	Speakers: Andra Lutu, Institute IMDEA Networks - UC3M Andra Lutu is a third-year PhD student at Institute IMDEA Networks and University Carlos III of Madrid, Spain. Since 2009, she has been working alongside her advisor, Marcelo Bagnulo, in topics closely related to interdomain routing. Her research interests orbit around BGP and its intricacies, with a focus on measurements and game theory models.
Abstract:	By tweaking the BGP configurations, ASes are able to express their interdomain strategies and deploy the above-mentioned policies. However, due to the complex interactions between networks, at times only defining a routing policy does not also guarantee its effectiveness in the Internet. For examples, sometimes, BGP routes end up being announced to entities to which the routing policies specifically state that they should not be. And it may also happen that, by default, all the routes are propagated to all BGP neighbours, once they have been accepted, disregarding of the origin’s strategies. Consequently, the network operators need to complement the view of the routing system from inside their network with multiple external views, in order to understand how their policies interact with the operations of the rest of entities in the interdomain and if the implemented policies are producing the intended or expected result.
