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.)
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 d...
