Hi all,
Next Monday (November 10), Ashley Flavel from University of Adelaide will be giving a talk on modeling IGP/iBGP interaction. Both systems and theory people may find this talk interesting.
Thanks, Yi -------------------------------------------------------- Time: 11:30-12:30, Monday November 10

Title: Where’s Waldo? Practical Searches for Stability in iBGP
Abstract: What does a child’s search of a large, complex cartoon for the eponymous character (Waldo) have to do with Internet routing? Network operators also search complex datasets, but Waldo is the least of their worries. Routing oscillation is of much greater concern. One cause of such oscillations is the interaction between the routing protocols used for reaching internal (IGP) and external destinations (iBGP). In this talk we model the interaction between these two routing protocols and precisely identify where oscillation can occur due to the interaction, and where it cannot. We apply this analysis to the iBGP configuration of a large Tier-2 ISP and show that despite the problem being NP-hard, we can restrict our search to a feasible size in a realistic network.
Short bio: Ashley Flavel is a Phd candidate at the University of Adelaide in the School of Applied Mathematics. He holds degrees from the University of Adelaide in both Telecommunications Engineering and Mathematical and Computer Science. His current research involves the measurement and modeling of the Border Gateway Protocol. He will be submitting his Phd thesis in late 2008. _______________________________________________ talks mailing list talks@lists.cs.princeton.edu https://lists.cs.princeton.edu/mailman/listinfo/talks
