In recent years, the size and dynamics of the global
routing table have increased rapidly along with an increase
in the number of edge networks. The relation between edge
network quantity and routing table size/dynamics reveals a
major limitation in the current architecture. In this paper we
introduce the two problematics target as the main cause for the
Internet scalability issue. Subsequently, we describe the different
proposals that address the scalability problem. We group them
in three categories: Separation, Elimination and GeographicPostprint (published version
