What is DTNRG?

The Delay-Tolerant Networking Research Group (DTNRG) is a research group chartered as part of the Internet Research Task Force (IRTF). Members of DTNRG are concerned with how to address the architectural and protocol design principles arising from the need to provide interoperable communications with and among extreme and performance-challenged environments where continuous end-to-end connectivity cannot be assumed. Said another way, we are concerned with interconnecting highly heterogeneous networks together even if end-to-end connectivity may never be available. Examples of such environments include spacecraft, military/tactical, some forms of disaster response, underwater, and some forms of ad-hoc sensor/actuator networks. It may also include Internet connectivity in places where performance may suffer such as developing parts of the world.

DTNRG members research aspects of delay-tolerant networking in a number of ways including academic publications, technical specifications, several active mailing lists, and code (reference implementation) development. DTNRG holds semi-regular teleconferences for software developers and occasional face-to-face public meetings. The public meetings usually occur in conjunction with an IETF meeting. The current co-chairs for DTNRG are Kevin Fall (Qualcomm), Stephen Farrell (Trinity College, Dublin) and Jörg Ott (Aalto University, Helsinki). Back in 2006 Stephen wrote a book on DTN.

Several of the members of DTNRG participated in the (highly-related) DARPA Disruption Tolerant Networking program.

Mailing Lists

DTNRG is an IRTF open research group. There are several mailing lists, depending on your interests, that you can subscribe to:

Posting is restricted to subscribed members, determined by the email address you are sending from (i.e., if you post to the list from an email address that is different from the one you are subscribed to, your post will be dropped silently).

Current Efforts

Virtual and Physical Meetings

The folks working on the implementation meet from time-to-time (about every other month in person and weekly on the phone). If you have resources to help with this effort (and are willing to travel), please post to the mailing lists indicating what you would like to do.
