We propose a novel visualization, IMap, which enables the detection of security threats by visualizing a large volume of dynamic network data. In IMap, the Internet topology at the Autonomous System (AS) level is represented by a <i>canonical map</i> (which resembles a geographic map of the world), and aggregated IP traffic activity is superimposed in the(More)
—Detecting malicious traffic streams in modern computer networks is a challenging task due to the growing traffic volume that must be analyzed. Traditional anomaly detection systems based on packet inspection face a scalability problem in terms of computational and storage capacity. One solution to this scalability problem is to analyze traffic based on IP(More)
Micro-mobility protocols aim to improve localized mobility by reducing the handover overheads. In this paper we present the Mobility Plane Architecture (MPA). This architecture was designed to support micro-mobility in standard IP or MPLS/GMPLS networks in a network-centric way, that is, the burden demanded by micro-mobility is placed on the network, not on(More)
