And now for something completely different, here is a new version of the Internet Routing Overlay Network (IRON) that identifies a new business model and new architecture for supporting scalable provider independent addressing and multihoming.
IRON now expects that Virtual Prefix (VP) companies will set up a business in which they lease portions of their address space to End User Networks (EUNs) as PI prefixes. EUNs can then "register" the binding of each PI prefix with an IP address that was assigned to them by an ISP. No other arrangements with the ISP are necessary. Multihomed EUNs can change their bindings on the fly to use a different ISP without having to relinquish their PI prefixes nor renumber their networks. All of this is realized through the deployment of a small number of commodity hardware platforms scattered throughout the Internet and with no changes to existing core routers. Pease see below for the abstract plus document URL. Please also note that this approach may be consistent with what the chairs' recommendation is calling "Aggregation in Increasing Scopes".

Title : The Internet Routing Overlay Network (IRON) Author(s) : F. Templin Filename : draft-templin-iron-01.txt Pages : 13 Date : 2010-04-28 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 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 are reaching a tipping point where something must be done. This document proposes an Internet Routing Overlay Network (IRON) for supporting sustainable growth while requiring no changes to end systems and no changes to the existing routing system.
