Thanks Will,

I'm aware of CCSDS/IETF raison d'etre. My thought is: If you guys say it is
good for millions of nodes, then it should be the same for 10s of them. I
just want to cross-check on that.

Thanks for the info :)

  Juan,

 Remember,  we are not just discussing space applications. We are
discussing general applications hundreds of millions of nodes.
Bundling may work well for your application in space with four or five
nodes, but perhaps not so much for general Internet.  Remember IETF is
INTERNET Engineering Task Force.  CCSDS is Space.  If IETF is going to work
on something, it needs to address the general needs of the Internet user
base, not just Space.  That is CCSDS' realm.

 A good overview:

 Some papers are here with link to  presentations.

 But above is just one viewpoint of ICN.  ICNRG should lead you to others.

  Hi Will,

 Where can I read (not slides) about how ICN handles routing, forwarding,
buffering, network-level congestion, and contact predictability? Is there
an RFC or good article about these?

 Thanks,

 Hi Kevin,

 Yes, I worked closely with this group.  Chart 19 says it all. Buy the
way, don't confuse the need for DTN with the need for the Bundle protocol.  
Chart
19 supports Wes' comments.  There is not way this group can deploy large
networks without item 2.

Challenging network environment leads to link and network disruptions

   1. Need to develop a robust DTN based transport service
   2. Requires solutions to addressing, routing, management, discovery
   and forwarding/QOS

 I have not seen this group actively participating on any of the DTN
mail list in the past year or two or perhaps more.  Time flies.

 Will

Based on a meeting I recently attended and 2014 references such as this:

(

)

I cannot share your conclusion.
