Hi Ricardo, Basically I want to measure the Convergence times and routing table sizes. But I am not able to find a good topology of internet which I can utilize for my experimentations. I am looking at GT-ITM, BRITE and IGen but don't know what kind of abstraction they provide and if these topologies are feasible to test the above mentioned parameters.
What challenges I can face if I want to measure all those parameters convergence times ,table sizes , update count, signal sizes etc. Regards Moazzam On Tue, Sep 2, 2008 at 1:35 PM, Ricardo Oliveira <[EMAIL PROTECTED]>wrote: > Moazzam, > > Do you have something specific in mind you want to measure? e.g. > convergence times, table size, update count, etc? the scope of your study > seems to broad as you describe it.. > Cheers, > > --Ricardo > > > On Sep 1, 2008, at 12:57 PM, Moazzam Khan wrote: > > Thanks Stefan for your reply. >> >> Basically the goal of this testing is to study the BGP scalability issues >> in >> the internet sometime in future lets say 10 years from now and try to find >> out what problems it could face .
