hi heiner, please note that we're considering routing at the AS level. long story short, some reasons to do so are outlined in our old paper http://dx.doi.org/10.1145/1273445.1273450
now, if your lsp stays within an AS, it's transparent for our stuff. if it hypothetically crosses (many) AS boundaries, then see dino's comment. best, dima. -- http://www.caida.org/~dima/ From: [email protected] [mailto:[email protected]] Sent: Tuesday, September 28, 2010 11:08 AM To: [email protected] Cc: [email protected]; [email protected]; [email protected] Subject: Re: [rrg] Fwd: Sustaining the Internet with hyperbolic mapping In einer eMail vom 28.09.2010 19:09:28 Westeuropäische Sommerzeit schreibt [email protected]: > Dima, > > There may be MPLS-LSPs which, at layer 3, make one router in Chicago > to a one-hop-neighbor of another router in Sydney.

Simply put, there are multiple paths between Chicago and Sydney. So a failure in the US, can be packet rerouted. If you want to compare with MPLS, it is just a circuit versus datagram argument. Which I will not get into because that would be way off topic. Dino Dino, this is a different issue and unrelated with the stuxnet topic. Henry Kissinger once said: It is difficult to applaude and shrug the shoulders at the same time. I must admit that being not convinced is also due to my lack of understanding intellectually. I guess, Dima and I have in common that we do not seek solutions within the frame given by DV and this awful prefix aggregation. But I am against that in such a way that I am against aggregated nodes (with internal topologies), no matter whether you call them ASes or peer groups or anything else. But Dima will certainly explain his concept Heiner _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
