Summary of the IAB Routing and Addressing workshop - Dave Meyer

The Internet’s routing system is facing a set of serious scaling problems ... none of the existing IETF efforts provides effective solutions

The scalability of the routing system is a problem and must be addressed in the near term; IPv6, in its current form, does not fix these problems

These problems are urgent

IP routing scaling issues - Vince Fuller

There are reasons to believe that current trends in the growth of routing and addressing state on the global Internet may not be scalable in the long term

• An Internet-wide replacement of IPv4 with IPv6 represents a once-in-a-generation opportunity to either continue current trends or to deploy something truly innovative and sustainable

• As currently specified, routing and addressing with IPv6 doesn’t really differ from IPv4 – it shares many of the same properties and scaling characteristics

... These kinda look exponential or quadratic; this is bad ... and it’s not just about adding more cheap memory to systems

... Without architectural or policy constraints, costs are potentially unbounded; even with constraints, service providers are doomed to continual upgrades, passed along to consumers
