2nd Annual IPN Speakers Conference
Showcasing Delay & Disruption Tolerant Networking (DTN): the Emerging Standard for Space Data Communications
Last year’s IPN speaking event—Space Technology Innovations: Enabling Exploration Above, Improving Life Below—presented how DTN can enable space data communications as well as provide network services in constrained terrestrial network environments. This year we are focusing upon DTN in the space arena. Our speakers include:
- Vint Cerf (Google VP, co-author of TCP-IP, one of the “fathers of the Internet—and IPN-ISOC board member) will provide an overview of InterPlanetary Networking.
- The NASA/Boeing team (Brett Willman & Suzanne Davidson) working on DTN aboard the International Space Station
- The NASA team (David Israel & Donald Cornwell) who concluded the very successful Lunar Laser Communication Demonstration in late 2013 and who are planning the 2017 Laser Relay Communication Demonstration.
- Scott Burleigh (JPL’s chief DTN architect) will be explaining recent significant enhancements to the ION DTN distribution (the distribution currently in use on ISS).
- Keith Scott leads the Consultative Consortium for Space Data Systems (CCSDS) DTN working group that is standardizing DTN protocols for use in civilian space missions. He will talk about the Bundle Protocol becoming one of the networking protocols being standardized for space communication as part of the Solar System Internet (the other is IP).
- Scott Pace is the Director of the Space Policy Institute at George Washington University. He will be speaking about the increasing importance of space policies as more nation states engage and collaborate in space exploration.
Admission is free and breakfast, lunch and an afternoon snack will be provided—but you MUST register to attend. Physical attendance is limited to 150 people. The event will be webcast on the Internet Society’s LiveStream channel and presentations will be available on YouTube for VOD streaming after the event.
The event starts at 9 a.m. Speakers conclude at 4:30 p.m. IPN-ISOC Meeting follows immediately after and concludes at 6 p.m.
Boeing is hosting our event at their Long Bridge facility at:
929 Long Bridge Drive, Arlington, VA, 22202

A speaker bio page will be posted soon.
The InterPlanetary Networking Chapter of the Internet Society (IPN-ISOC) is presenting its second annual Space Technology Innovations Conference at the Boeing Long Bridge facility in Arlington, VA (just outside Washington, DC) on Monday, May 18th, 2015.
Dr. Vinton Cerf (Google VP; co-author of TCP-IP—one of the “Fathers of the Internet”)
Scott Pace (Director of the Space Policy Institute at George Washington University)
Brett Willman (NASA JSL Manager), Suzanne Davidson (Boeing ISS DTN Lead)
David Israel and Don Cornwell (NASA Goddard Space Flight Center)
Full speaking agenda and speaker bios will be posted soon.
The event will be webcast live over the Internet Society’s LiveStream channel, and videos of the speaker presentations will be available for on demand streaming.
Admission is free and includes continental breakfast, lunch and an afternoon snack. The speaking agenda will be followed by the annual meeting of the chapter.
Board member Keith Scott provides this update on DTN activities within CCSDS.
CCSDS is in the process of review and approval of two key DTN protocols of particular interest to the InterPlanetary Networking community: the Licklider Transport Protocol and the Bundle Protocol. CCSDS approval will establish LTP and BP as Space Data Systems standards for all member space agencies.
LTP review is pretty much all but done. BP is in its third member agency review, and is scheduled to complete that review in October, 2014.
In other news, deployment of DTN for operational communications between earth and the International Space Station is expected to occur this Fall. The NASA Change Request for deploying DTN for ISS operations was approved in 2013. DTN is already used for most communications between ISS experimental payloads and earth-based researchers and operators.
The fifth annual IEEE Space Mission Challenges for IT (SMC IT) Conference is coming up September 24th – 26th, 2014, at Laurel, Maryland. There will be a Space Terrestrial Internetworking (STINT) workshop co-located with the SMC IT conference. The theme for the workshop will be “Operationalizing the Network Environment”. Presentations will cover the following topics:
- Delay and Disruption Tolerant Networking
- Modeling the Dynamics of Mobile Space-Based Networks
- Autonomous Configuration and Control of Network Nodes
- Protocols, Applications, and Concepts for Network Management
- End-to-end Security Services Across an Internetworking Overlay.
- Commercial, Scientific, and/or Government Missions Enabled by Space-Terrestrial Internetworks

Many thanks to Juan Fraire for the excellent workshop poster.

There is an approved DTN Birds of a Feather (BoF) group meeting at IETF 90. It’s currently scheduled for 1520 – 1650 on Wednesday, July 23rd. For more information about the BoF group, including charter, problem and solution statements, go to: http://trac.tools.ietf.org/bof/trac/wiki/WikiStart
For the most current IETF agenda, including the room for the BoF, go to: http://trac.tools.ietf.org/agenda/90/
For the BoF meeting agenda, go to: http://trac.tools.ietf.org/agenda/90/agenda-90-dtnwg.html
This is an important first step on the road to standard adoption for DTN. If you are attending IETF, we strongly encourage you to attend the DTN BoF.
Fred Templin (Boeing) has been leading the charge to initiate a Birds of a Feather (BOF) group at this July’s IETF meeting in Toronto, Canada. A mailing list has been created to discuss the organization of the group. You can get more information and sign up for the list at:
An introductory message including the draft working group charter and proposed BoF agenda will be published soon.

Here’s an interesting article on the Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES—and isn’t THAT a reach for a catchy acronym?) on board the International Space Station (ISS) from NASA Ames Research Center: http://www.nasa.gov/mission_pages/station/research/news/smart_spheres/#.UyxiVPldWa9
The photos below show SPHERES—small, self-propelled robotic sphere (rather: sphere-like) units about the size of a volleyball that are being tested on board ISS for various maintenance and emergency repair tasks. SPHERES have used Android smart phones for communication and control since 2011. Now a new version is being flight tested before being launched later this year to provide enhanced capabilities (such as a 3-D positional sensor). The phone being tested is the Google Project Tango Android smart phone.

NASA recently announced a significant review milestone for the Laser Communications Relay Demonstration (LCRD) scheduled for 2017.
The LCRD project is NASA’s first long duration optical communications mission. This demonstration builds upon NASA’s highly successful Lunar Laser Communications Demonstration (LLCD) mission (which validated the use of DTN for laser communications to the moon and back). LCRD will conduct a two-year demonstration of optical relay services to determine how well the system operates and collect long-term performance data. Full details are available here:
