Evolution Towards Global Routing Scalability
Internet routing scalability has long been considered a serious problem. Over the years many efforts have been devoted to address this problem, however the IETF community as a whole is yet to achieve a shared understanding on what is the best way forward. We step up a level to re-examine the problem and the ongoing efforts, and conclude that, to effectively solve the routing scalability problem, we first need a clear understanding on how to introduce solutions to the Internet, which is a global scale deployed system. In this draft we sketch out our reasoning on the need for an evolutionary path towards scaling the global routing system, instead of attempting a new design.
