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 …

Network operators often face the problem of remote outages in transit networks leading to
significant (sometimes on the order of minutes) downtimes. The issue is that BGP, the …

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 robustness of the Internet relies heavily on the robustness of BGP routing. BGP is the
glue that holds the Internet together: it is the common language of the routers that …

The IP address consumption and the global routing table size are two of the vital parameters
of the Internet growth. In this paper we quantitatively characterize the IPv4 address …

A number of previous measurement studies [10, 12, 17] have shown the existence of path
exploration and slow convergence in the global Internet routing system, and a number of …

BGP has been deployed in Internet for more than a decade. However, the events that cause
BGP topological changes are not well understood. Although large traces of routing updates …

The lack of an accurate representation of the Internet topology at the Autonomous System
(AS) level is a limiting factor in the design, simulation, and modeling efforts in inter-domain …

The security of Internet routing is a major concern because attacks and errors can result in
data packets not reaching their intended destination and/or falling into the wrong hands. A …
