We have done considerable work in the area of delay- and disruption-tolerant networking (DTN), building on our initial co-operation around testing CLEO, the Cisco router in Low Earth Orbit. We are the first to test the "Bundle Protocol," intended for the Interplanetary Internet, in outer space.

Our work, also described in video presentations, includes:

Practical work
Interplanetary Internet work
We have performed practical work in testing the Internet in space, and in being the first to test IPv6 and the Bundle Protocol in space.

Saratoga
a fast data transfer protocol, originally developed at Surrey Satellite Technology Ltd (SSTL) and taken to the Internet Engineering Task Force (IETF) for public scrutiny.

Theoretical work
Bundle Protocol work
We carried out theoretical analysis and assessed the Internet Research Task Force Delay-Tolerant Networking Research Group's preferred approach of the Bundle Protocol, found drawbacks, and have proposed workarounds.

HTTP-DTN
We have proposed HTTP-DTN as an alternative, simple, approach to delay-tolerant networking, leveraging existing popular HTTP and MIME protocols and the applications that use them.
