I've been involved in DTN since the DARPA days and I registered the spacenetworking.com domain some time back.  I have not done anything with it and see no immediate use for it.  Does anyone involved with DTN want to use the domain?

Excellent! Be interested to see how folks put this
to use.

Now that we've got even more implementations, does
anyone (with an a/c) feel like doing an update to the
"Code" page on the wiki? [1] I'll put it on my to-do
list but it'll be (at least) a few days before I get
to it.

Subject: [dtn-interest] pydtn alpha released

The alpha version of the pure python dtn implementation has been released.

It's available by doing the following:
hg clone http://dtn.sourceforge.net/hg/pydtn

It has been tested to interoperate with the DTN 2.6 reference
implementation, sending and receiving bundles of arbitrary size over
the tcpcl. However, it has not been extensively tested, and there are
no doubt many bugs. Feel free to find those for me! Also, as it's
alpha software, it's not a terribly elegant implementation in places.
I hope to remedy that in time.

My current work is to port this to the pys60 environment on the
Symbian operating system.

Thanks!

The first part was in reference to "starbucks", a notion described in  
some of the IPN-related documentation.  It is also used in various  
credit schemes in networks.

The second thing is detailed somewhat more in this:

M. Seligman, K. Fall, and P. Mundur. �Alternative Custodians for  
Congestion Control in Delay Tolerant Networks�.
Proceedings of 2006 ACM SIGCOMM Workshop on Challenged Networks, pp

Subject: [dtn-interest]  About DTN congestion management

Dear all,

I just read Kevin's paper about DTN architectural retrospective, where a
statement goes as follows:

"Without the conventional type of low-latency feedback available
in ordinary networks, congestion management and control can be
exceedingly difficult. The approaches suggested to date tend
to involve either allocated credits that are carried in packets
in exchange for storage over time or mechanisms designed
to offload congested nodes using storage available in local
neighborhoods."

I am wondering if anyone can kindly point me to some references for the
two suggested approaches mentioned in the statement? These sound
interesting to me but seem to take care of storage issue only, so I will
like to see what they say. Thanks in advance for your help!

Best,
Chin-Tser

Thanks Eddy. I've relayed this to the TICTOC Group. The only real requirement seems to be that TICTOC allow one-way time transfer. 

Sincerely,

After reading the latest TICTOC requirements draft, I don't
think there should be any requirement on TICTOC for supporting
DTN time synchronization.  The TICTOC requirements are broken
down by the "application" driving them, and if you considered
synchronizing DTN bundle agents to be one of those applications,
then the requirements would be orders of magnitude easier than
for the other applications like cellular towers.  The cellular
backhaul requirements have things like a time accuracy on the
order of microseconds, and frequency stablity in a few dozen
ppb, both of which vastly exceed what bundle agents need.  The
only unique aspect of DTN that influences the capability to use
TICTOC is that unidirectional time-transfer should be possible
(not requiring real-time acknowledgements, or any feedback
channel at all).  It seems like this will be the case for some
of the already-identified TICTOC applications like Time-of-Day,
"legal time", and metrology, where a master clock signal is
distributed out to essentially slave nodes.  The TICTOC
requirements don't seem to exactly say that unidirectional
time-transfer needs to be supported, but as multicast is a
natural fit given a single source and dozens/hundreds of sinks,
it seems like it will develop to permit unidirectional use on
its own.

A DTN has 2 needs for timing signals:

1) A bundle agent can have start times or periodicity associated
   with some of its contacts with other bundle agents.  In order
   for a system to do things like turn radios on, point antennas,
   etc., it will need an accurate sense of time.  If these
   activities occur outside the bundle agent, some means of
   synchronizing the bundle agent's actions with the rest of the
   system is needed.  If the bundle agent runs within the same
   computer that performs these other actions, then the system
   clock itself is sufficient.  In the worst case, the bundle
   agent will likely still be part of an integrated unit with
   the rest of the system that controls antennas, amplifiers,
   etc. and can use some local time distribution means to keep
   in sync onboard a spacecraft or other deployment platform.

   However, the bundle agent on the other end of the contact may
   also need to have its communications equipment configured at
   the same time in order for the contact to start right away.
   Any skew in system times can cut into the usable contact time.
   But since, by definition, the bundle agents aren't in contact
   before the scheduled contact time, there's not much hope of
   something like TICTOC keeping them in sync because it can't
   create comm links where none exist :).  Once the links are
   up, time-transfer could be used to correct for any skew and
   help future contacts, but some damage may have already been
   done to the current contact.

   For this, the only requirement on using TICTOC would be
   that it allow for unidirectional time-transfer, not relying
   on acknowledgements.  How time-transfer signals are treated
   is a thornier operational problem for DTNs, as we cannot
   always assume a simple master-slave relationship where one
   side of a contact always delivers clock and the other always
   accepts it.  But this is mostly a policy issue in each
   particular case of DTN deployment.

2) When a bundle agent creates a bundle, it adds a "creation
   timestamp" to the bundle, as well as a "lifetime" after
   which the bundle is considered to be expired, and discarded.
   These fields are checked by intermediate and destination
   bundle agents.  Some potential issues that can come from
   clock skew involve:

   - "bundles from the future" where a sender's clock gets ahead
     of another bundle agent on the path's and so the creation
     timestamp appears to be in the future.  Some systems may
     choose to discard these as invalid.

   - "bundles thrown out too soon" where a sender's clock is
     too far behind another bundle agent on the path's relative
     to the expiration lifetime.  In this case, bundles can be
     discarded before the sender intended them to be.  This can
     affect applications that set a short lifetime such as
     dtnping, VoBP/VoDTN (Voice over Bundle Protocol / DTN), etc.

   The correct way to deal with this is by changing the semantics
   of the creation timestamp and lifetime fields in the bundle
   protocol (I believe Joe Ishac described this some time ago),
   rather than levy any requirement on TICTOC which would be
   difficult to define or achieve given the intermittently-
   connected, spatially-dispersed, and possibly mixed ownership
   and control of nodes in a "typical DTN".

As promised, To keep DTNRG and SIS-DTN informed:

DTN Network Management - Collaborators
Meeting Notes for
Monday, December 8, 2008
1:00 - 2:00 EST (81:00 - 19:00 UTC)

A teleconference was held on Monday, December 8th.  The following
teleconference will be January 5th, 2009 due to the holidays.

Participants:
*	BBN - Cambridge
*	Hans Kruse  - Ohio University
*	Rajesh Krishnan - Scientific Systems 
*	Will Ivancic and Wes Eddy - NASA Glenn
*	Scott Burleigh - NASA JPL
*	Vishwas Rudramurthy - Aricent (India)
Agenda:
==========

Requirements Document - Suggested by Robert Coles

- combined short problem statement and requirements
- some requirements
 -- local network management
 -- remote network management using bundle protocol
 -- local network configuration
 -- remote network configuration using bundle protocol

GRC will be establishing a lunar strawman network on the OpenNet in
order to stress links and experiment with network management and
configuration
 - conceptual diagram attached
 - IPv6 for network management
 - DTN Gateway will also contain WiKi for displaying network conditions
/ routes / items that we conclude are worth displaying

Various groups from IRTF expressed interested in networking machines
together - will send probe to DTNbone list
 - http://korgano.eecs.ohiou.edu/mailman/listinfo/dtnbone
 - [email-masked]

Results:

It was agreed that a requirements document should be generated ASAP.
This document should include as least the following three items:

1)	A short problem description (as apposed to creating an entirely
separate problem statement document);
2)	A set of operations scenarios (Concepts of Operations - CONOPS)
from which the requirements and rational are based; and
3)	A set of requirements and corresponding rational.  Suggest
format similar to:
http://roland.grc.nasa.gov/~ivancic/shared/ietf/draft-eddy-nemo-aero-req
s-02.txt
http://roland.grc.nasa.gov/~ivancic/shared/ietf/draft-eddy-nemo-aero-req
s-02.html

Will Ivancic volunteered to write the draft and is willing to accept
help.  At a minimum, an outline of the document with some requirements
and scenarios will be filled in by January 5th.   Once the document
obtains a reasonable state of maturity, it will be submitted as an
Internet Draft to allow the DTNRG working group to review and comment.

Scenarios should include:  Sensor Networks, Data Mule (rover or UAV),
Deep Space and perhaps something related to rapid disruption such as
were something like Voice Over IP is desired over DTN - radio fades.
There also should be an acknowledgement of the different requirement
that may result from predictive versus completely opportunistic type
networks.

Networks for Testing
NASA GRC will be putting together a space-based network for testing as
depicted in:
http://roland.grc.nasa.gov/~ivancic/shared/OpenNet_Lunar_Strawman.pdf

This will allow us to flow enough data to begin understanding what items
are useful to monitor to understand DTN operations.  Page 2 shows a real
time control plane.  Has Kruse observed that such a real-time control
plane for testing is like the lattice work when build a tower.  It is
necessary during development in order to understand what is happening.
This also argues for use of something like SNMP as a basis for the DTN
network management as while the DTN network management application and
DTN network management transport are being developed, SNMP can be
exploited early on for debugging and monitoring.

Hans Kruse is requesting information from the DTNRG group on who is
interested in connecting their DTN networks.  He will compile this
information and publish it - probably via a wiki.  The goal is to have
about six sites connected by March 2009.  This will likely be a good DTN
network from which we can test DTN network management.

Random Thoughts / Issues /Requirements:

We need to consider Fault, Configuration, Accounting, Performance,
Security (FCAPS) with regard to DTN. ( FYI -
http://en.wikipedia.org/wiki/FCAPS)

Bandwidth Efficiency (and resource utilization) needs to be considered
regarding DTN transport and the amount of information passed over the
networks.

Keep Measurements (real data) separate from Computed data (such as
estimated time of arrival) in order to ensure real versus what will be
predicted and probably often incorrect conclusions from the DTN measured
data.

Need to monitor and provide information on Resources (storage, battery
life, ect...), convergence layers, routing information, QOS policies,
configuration information such as First In First Out vs Last In First
Out type configuration and other "routing policies".

Need to monitor security configurations in a secure manner.
