It is well-known that simple, accidental BGP configuration errors can disrupt Internet
connectivity. Yet little is known about the frequency of misconfiguration or its causes, except …

This paper presents a methodology for identifying the autonomous system (or systems)
responsible when a routing change is observed and propagated by BGP. The origin of such …

This paper presents a detailed study of BGP Multiple Origin AS (MOAS) conflicts observed in
the Internet. A MOAS conflict occurs when a particular prefix appears to originate from more …

The Internet is composed of many independent autonomous systems (ASes) that exchange
reachability information to destinations using the Border Gateway Protocol (BGP). Network …

Border Gateway Protocol (BGP) plays a critical role in the Internet inter-domain routing
reliability. Invalid routes generated by mis-configurations or forged by malicious attacks may …

Prefix hijacking has always been a big concern in the Internet. Some events made it into the
international world-news, but most of them remain unreported or even unnoticed. The scale …

The performance of a backbone network is vulnerable to interdomain routing changes that
affect how traffic travels to destinations in other Autonomous Systems (ASes). Despite …

The Internet's interdomain routing protocol, BGP, is vulnerable to a number of damaging
attacks, which often arise from operator misconfiguration. Proposed solutions with strong …

The scalability limitations of BGP have been a major concern lately. An important aspect of
this issue is the rate of routing updates (churn) that BGP routers must process. This paper …

BGP prefix hijacking is a threat to Internet operators and users. Several mechanisms or
modifications to BGP that protect the Internet against it have been proposed. However, the …
