In another mailing list, someone has asserted that "noone believes router vendors who say [they can support 2M routes today and 10M with no change in technology]".
Do you believe router vendors who state they today have "capacities on the order of 2 million ipv4 routes and they have no reason to expect that they couldn't deliver 10 million route FIB products in a few years given sufficient demand."?
David, NNTP is similar to BGP in that every message must spread to every node. Usenet scaled up beyond what anyone thought it could. Sort of. Its not exactly fast and enough messages are lost that someone had to go invent "par2".
- where do you believe existing routing technology will fall down?
I guess you could say that I think BGP has an NNTP future. It never quite breaks completely, it just gets worse and worse at doing its job.
- what steps will you take/are you taking to limit your vulnerability?
As a multihomed endpoint network, I can sacrifice some reliability by introducing a default route and filtering longer prefixes if I really have to. I hope the folks upstream have a better answer.
