Heat Up BGP Routing This talk presents an analysis of the influence of intradomain routing changes on BGP routing and transit traffic for the AT&T domestic backbone. We propose a general methodology for associating BGP update messages with events visible in OSPF. Then, we apply our methodology to streams of OSPF link-state advertisements and BGP update messages from the AT&T network and correlate BGP egress-point changes with Netflow data to study the impact of routing changes on the traffic matrix. Our analysis shows that:
This is joint work with Aman Shaikh (AT&T), Tim Griffin (Intel), and Jennifer Rexford(AT&T). Renata Teixeira is a post-doc at the Universite Pierre et Marie Curie in the Laboratoire d'Informatique de Paris 6. She has recently finished her Ph.D. at the University of California, San Diego in the Department of Computer Science and Engineering. During her Ph.D., Renata worked at the AT\&T Labs in Florham Park. She received her B.Sc. in Computer Science and M.Sc. in Electrical Engineering from Universidade Federal do Rio de Janeiro, Brazil in 1997 and 1999, respectively. Her research interests are in measurement and analysis of routing protocols, and in management of large IP networks. 2. Estimating
the Traffic Matrix in IP Networks. Mathematical models exist for the estimation of traffic matrices. In this presentation we compare the results of these models to measured/known traffic matrices, and discuss their usage and applicability in IP networks. 3. AMS-IX Net Performance Measurements (15 min) The Amsterdam Internet Exchange is using RIPE TTM boxes for measuring the performance of their layer 2 infrastructure. These measurements are published at the AMS-IX website in the form of a monthly report, generated by the RIPE tools and in the form of a real-time look, generated by self written scripts. AMS-IX uses this data for monitoring the health of the platform as well as providing a measurement tool for the quality of service to the AMS-IX members. 4. Improving
the Security and Robustness of Internet Routing.

and Grid Security: XML Web Services vulnerabilities and threats
analysis. Many research organisations and consortia are developing worldwide Grid infrastructure for research purposes. Commercial companies are mostly deploying and testing Grids on the intranet but with the technology maturing will use Grid technologies on the Internet. Cisco and Nortel are actively promoting Application Oriented Networks (AON) which are Web Services enabled. Grid and Web Services generate significant and non-typical traffic on the Net. This traffic actually bypasses traditional security Firewalls but can access critical resources and therefore impact their normal work. In Grid projects, there is ongoing activity to address new possible threats and attacks. This work is conducted in the framework of the EU project
EGEE (Enabling Grid for E-SciencE). This page has been updated:
