There has been much discussion over the last years about the overall scalability of the Internet routing system. Some have argued that the resources required to maintain routing tables in the core of the Internet are growing faster than available technology will be able to keep up. Others disagree with that assessment. This document attempts to describe the factors that are placing pressure on the routing system and the growth trends behind those factors.
