[Sis-dtn] SIS-DTN Input to SIS report to CESG

[sburleig.sb at gmail.com]

Bob, excellent summary, and congratulations on herding this virtual room
full of cats so successfully!

 

I have two comments:

*	On slide 4 I think you want "known critical path" rather than "know
critical path".
*	Given that we cannot call DTN multicast "multicast", for reasons
which continue to elude me, I would strongly urge us to adopt the term
"multipoint" (as on slide 2) in place of of "multi-destination".
"Multi-destination" is simply, factually, technically incorrect.  Like every
bundle, each bundle sent via this mechanism has only a single destination -
the endpoint identified by some imc-scheme EID.  The only difference is that
this single destination endpoint need not be a singleton endpoint.  We have
called this "multipoint" for a couple of decades.  We should continue to use
that language.

I neglected to mention the resolution to reaffirm LTP with the corrigendum
that is under review within the WG.  I added that, along with the WG motto
for the week:  "Orange is the New Blue."  (Depending on the sense of humor
of the CESG, you may want to strike that remark, which is at the top of
slide 2.

 

Best,

Bob

Tomaso,

 

Thanks to the members of the SIS-DTN WG for what I consider to be an
enormously productive meeting, and thanks especially for helping me to get
up to speed as WG chair.

 

Attached please find the SIS-DTN report for incorporation into your SIS
report to the CESG.  Apologies for the length, but there is much to report
and update.

 

The key resolutions coming out of this meeting are as follows:

*	Submit BPSec for Agency Review
*	Charter DTN Multi-Destination Orange Book work item

 

Do you formulate those resolutions or do we?  What is needed to charter the
DTN Multi-Destination (aka, but don't call it, multicast)?  If I need to
formulate those resolutions, by when do you need them?  (And can you point
me toward a somewhat current example?)

 

You will note that we have had to be rather ruthless in deferring or
eliminating work items that do not seem feasible to complete in the context
of the needs and need dates we identified during our review of mission
capability needs.  If these need further explanation/rationale, please let
me know.

 

If you have any questions, please call me at +1 703-217-7414.  I will be
flying between about 8am and noon CDT tomorrow (Saturday).  

 

Thanks and best regards,
Bob
