This memo describes a proposal made to to the Routing and Addressing group [ROAD] January 1992 by Robert Hinden. It was originally sent as an email message. It proposes a medium term solution to the Internet’s routing and addressing problems.
I would like to propose a new scheme which I believe is a good medium term solution to the routing and address problems of the internet. It has the following positive attributes:
- No Changes to Hosts - No Changes to Most Routers - No New Routing Protocols - No New Internet Protocols - No Translation of Addresses in Packets - Reduces the Routing Table Size in All Routers - Uses the Current Internet Address Structure
It is not a solution good for all time, because it does impose some size limits and does not support new internet services such as guaranteed bandwidth, delay, etc. It does require border routers to do additional processing, but does not require any packet translation. I believe that this scheme will give us enough time to put into place a long term solution (i.e. pick one or more of CLNP, *NAT, IDPR, IDRP, Nimrod, Unified, NewIP, etc.)

RFC 1955 IP Encaps June 1996
This scheme is based on the ideas presented by Deborah Estrin (route on ADs), Martha Steenstrup (encapsulation), and probably steals from ideas put forward by Noel Chiappa, Van Jacobson , Ross Callon, Dave Oran, and everyone else in the ROAD group.
I think that we (the ROAD group) agree that in the short term we need to make better use of the IP address space. I think we also (mostly) agree that in the long term we need a solution that can deal with a very large number of end points and routes, as well as support new services such as guarantees of service, source selected routes, etc. We do not agree on any of the details of this but do agree that we can not figure out a long term solution before March. We do agree that we should start working on a long term solution(s).
What this leaves is the need for a good medium term solution which can keep the Internet going until we can design and deploy a long term solution. The medium term solution wants to be the most "cost effective". It should buy us the most time to develop a long term solution and do it with as little change to the existing Internet as possible.
I propose this scheme as a new medium term solution.
