The Internet routing system is experiencing a growth profile that has
led many to express concerns for unsustainable routing scaling.
Operational practices such as increased use of multihoming with IPv4
Provider-Independent (PI) addressing are resulting in more and more
fine-grained prefixes injected into the routing system from more and
more end user networks. Furthermore, depletion of the remaining
public IPv4 address space has raised concerns for both increased
deaggregation (leading to yet further routing scaling) and an
impending address space runout scenario. At the same time, the IPv6
routing system is finally beginning to see significant growth in IPv6
Provider-Aggregated (PA) prefixes but there does not seem to be a
solution on the near term horizon for IPv6 PI addressing. Since the
Internet must continue to support escalating growth due to increasing
demand, it is clear that current mechanisms and operational practices
must be updated. This document therefore proposes an Internet
Routing Overlay Network (IRON) for supporting sustainable growth
through PI addressing while requiring no changes to end systems and
no changes to the existing routing system. This document is a
product of the IRTF Routing Research Group (RRG).
