Towards Understanding City-Level Routing Using BGP Location Communities

Author image
Thomas Krenc

5 min read

BGP location communities offer a rare glimpse into where networks actually interconnect, but most remain undocumented and opaque. This work shows that, by exploiting a measurable spatial signal in routing data, it is possible to infer their city-level meaning at scale using only passive observation…

Beyond the Network View: DNS-Driven Application Visibility

Author image
Danny Lachos

6 min read

Network operators often lack visibility into which applications drive their traffic. We present an open-source DNS-based correlation method that enriches NetFlow and BGP data with application and CDN information. This enables a shift from a network-centric to an application-oriented view of traffic.

Make This One Change to Prevent Routing Loops in Your Network

Author image
Maynard Koch

5 min read

Routing loops can trap packets between routers, preventing them from reaching their destination. In some cases, routers even duplicate looping packets, amplifying traffic and threatening Internet stability. We look at how this happens and how operators can prevent it.
