Re: [Coin] FW: New Version Notification for draft-trossen-rtgwg-routing-beyond-reachability-00.txt

so the checklist for any new routing approach is the three M's

-Mobility
-Multihoming
-Multicast

extra marks  are avaialble for:

security:
+typically integrity of routes
+mitigate or don't make worse DoS
+retain as much (optinal) anonimity as people want

policy:
by which i mean anything that isn't just optimisation against some performance metric.

so my fave work out of all the future internet work 20 years back was I3
http://i3.cs.berkeley.edu/publications/papers/i3-sigcomm.pdf
as it asically spoke to the three Ms directly, by putting
rendezvous points in the net as a first class piece of the architecture
(obviously RPs had shown up in multicast as cores or in PIM already
but this generalised that) - then it falls to the designer to addres the extra mark
challenges, once you put a 3rd party in the net, you create a lovely pivot for all sorts of
attacks - hence it behoves us in groups like coin, to think about how you secure this
and it is now a three body problem, which we all know to be very much harder than two.

and that really is in-net compute in a nutshell...

> Abstract:
>    This document discusses the evolution of the Internet routing system
>    beyond mere reachability.  We observe, through examples of past
>    development, that such evolution has been taking place to improve on
>    capabilities of the Internet, deal with more complicated network
>    deployments and cater to changing requirements by end users as well
>    as novel and emerging applications.
> 
>    For achieving a routing system that serves more than a singular
>    reachability purpose, more information is taken into account when
>    performing the purpose-specific functions.  Such extra information
>    can be obtained by extending current routing protocols to exchange
>    more information or by carrying that information within packets.
> 
>    This document is intended to seed discussions of how the observed
>    evolution of the Internet's routing system can continue, what issues
>    may occur when simply continuing the current approach for achieving
>    routing beyond 'mere' reachability and what may be needed to address
>    those issues.  Ultimately, however, this document recognizes the
>    positive impact that moving beyond reachability has brought to the
>    Internet and will continue to do so.
