Hi.

Attached are the bibtex refs for a selection of DTN multicast routing 
papers, some of which are more recent than 2009.

Part of the issue is that we have never really sorted out multicast 
addressing in DTN.  In principle EIDs can be multi-point but the DTN2 
code doesn't handle the multi-point case in any sensible way.

I looked at how to handle this when implementing the netinf ICN protocol 
over the BP and came up with some ideas that actually hark back to the 
service type addressing/naming that was discussed in DTNRG.  See 
draft-irtf-dtnrg-dtn-uri-scheme-00.txt and a presentation at the DTNRG 
meeting at Google in 2009 (see DTNRG slides at IETF 74 for web ref).  
There was also intentional naming - see draft-pbasu-dtnrg-naming-00.tx 
and presentations at IETF 65, 71, Google meeting before IETF 74, 75.

Unfortunately very little of this has been implemented.

Regards,
Elwyn
