The BGP Visibility Scanner

Abstract

By tweaking the BGP configurations, the network operators are able to express their interdomain routing preferences, designed to accommodate a myriad goals. Given the complex interactions between policies in the Internet, the origin AS by itself cannot ensure that only by configuring a routing policy it can also achieve the anticipated results. Moreover, the definition of routing policies is a complicated process, involving a number of subtle tuning operations prone to errors. In this paper, we propose the BGP Visibility Scanner which allows network operators to validate the correct implementation of their routing policies, by corroborating the BGP routing information from approximatively 130 independent observation points in the Internet. We exemplify the use of the proposed methodology and also perform an initial validation for the BGP Visibility Scanner capabilities through various real operational use cases.16th IEEE Global Internet Symposium 16th IEEE Global Internet Symposium

The State of the Art in BGP Visualization Tools: A Mapping of Visualization Techniques to Cyberattack Types

“…Other papers were visualization-specific, but focused on different aspects such as exploration processes when using BGP visualizations [72], visual metaphors [32], and evaluation of specific visualization techniques such as using link weights [42]. Finally, we also explored higher-level papers that were not necessarily domainspecific, such as one that visualized collective anomalies [70] and a system to validate routing policies [44].…”

“…We probe addresses in ∼6.1M IPv4 /24 prefixes using this list. Under recommended best practices, /24 is the most-specific prefix length that globally propagates via BGP on the Internet [177]. For this reason, once we classify a target IP address as anycast or unicast, we extend this classification to its covering /24.…”
