Content-Centric Networking at Internet Scale through The Integration of Name Resolution and Routing
We introduce CCN-RAMP (Routing to Anchors Matching Prefixes), a new approach
to content-centric networking. CCN-RAMP offers all the advantages of the Named
Data Networking (NDN) and Content-Centric Networking (CCNx) but eliminates the
need to either use Pending Interest Tables (PIT) or lookup large Forwarding
Information Bases (FIB) listing name prefixes in order to forward Interests.
CCN-RAMP uses small forwarding tables listing anonymous sources of Interests
and the locations of name prefixes. Such tables are immune to Interest-flooding
attacks and are smaller than the FIBs used to list IP address ranges in the
Internet. We show that no forwarding loops can occur with CCN-RAMP, and that
Interests flow over the same routes that NDN and CCNx would maintain using
large FIBs. The results of simulation experiments comparing NDN with CCN-RAMP
based on ndnSIM show that CCN-RAMP requires forwarding state that is orders of
magnitude smaller than what NDN requires, and attains even better performance
