Flexible Routing with Maximum Aggregation in the Internet

TLDR: In this paper, the authors present a prototype implementation of the routing architecture based on parallel routing tables, which is an easy and clean alternative to current practises in order to avoid routing configurations that intend to have effect on a scoped area of the Internet are leaked outside it.

Abstract: The explosion of the Internet’s routing tables has been a concern in the last years Specially after IANA assigned the last /8 prefixes on the 3 rd of February, 2011, two fronts are open for the Internet community: the growth of the IPv4 routing table due to fragmentation introduced by the last assignments made by RIR and the strategy to follow for the new IPv6 Internet This paper analyses the behaviour of the IPv4 routing table in the Internet’s Default Free Zone in 2010 and presents the evolution and the current status of the IPv6 routing table in the DFZ These paper also presents a prototype implementation of the routing architecture based on parallel routing tables This prototype implementation was tested in an emulated environment using Netkit This implementation demonstrates that parallel routing tables are an easy and clean alternative to current practises in order to avoid routing configurations that intend to have effect on a scoped area of the Internet are leaked outside it This characteristic makes parallel routing tables a good candidate for Traffic Engineering configurations in IPv6
