Abstract: In this talk, we share our work in creating an “IPv4 as a service” network overlay. We begin by suggesting there is value in building network infrastructure which is “lean” and "IPv6 focused". There is likely value in focusing on a lean FIB infrastructure and IPv6 focused functionality in our next-generation routing platforms.

We performed traffic analysis on how IPv4 is being used in our network today. We found that 90% of the traffic in our fully routed backbone is done by %0.005 of the routes. 99% of the traffic is performed by 4.5% of the prefixes. This data suggests we can incrementally deploy an IPv4aaS solution. Our goal is to build an IPv4aaS using cloud infrastructure based on open source and home grown software.

We then present an IPv4aaS built on top of LISP. While we use LISP encapsulation, we have decided not to use the LISP DDT “routing” mechanism. Our IPv4aaS overlay routing architecture must associate IPv4 prefixes with IPv6 next-hops. This isn’t supported with “classic” BGP today. To solve this, we augmented JSON BGP IPv4 prefix updates with additional JSON information, namely an IPv6 next-hop. Effectively, we created a BGP IPv4 update with an IPv6 next-hop value. These messages are HTTP PUT to a route reflector / controller device, which processes the updates and applies associated business rules. These messages are then HTTP PUT to the overlay ingress (iTR) which announce a “default” to the underlay network.

We then suggest the concepts in this presentation are an extension to the concepts we've made at the previous two June NANOG meetings.
