Test bed offer

One of the goals set out in the Networking for Communication Challenged Communities (N4C)

project proposal was for the creation of a test bed for Delay- and Disruption-Tolerant Networking (DTN) that would

be sustainable beyond the lifetime of the N4C project. A dedicated effort investigated how it might be possible to

integrate the test beds created in the project into the larger federation of test beds proposed under the FIRE banner.

Three levels of business models have been developed for continuing test beds:

Level 1: A research test bed platform operating at a similar intensity as during the N4C Framework Programme 7 (FP7) project.

Level 2: A small scale test bed providing facilities for present research partners in N4C and for a few new clients.

Level 3: A large scale federated test bed operating in collaboration with the FIRE test bed network and providing

facilities as a general service.

The plan for the Slovenian N4C test bed offer to the FIRE federation was developed by Marija Zlata Boznar, MEIS d.o.o., assisted by Elwyn Davies, Folly Consulting Ltd. as advisor.

The N4C test bed in Slovenia has reached a point where it is likely to be sustainable beyond the end of the project. This test bed was developed by

N4C partner MEIS and MEIS are willing to incorporate the test bed capabilities into a future federation subject to appropriate agreements.

In the N4C offer to the FIRE federation, the Slovenian test bed is offered as a sustainable test bed operating at Level 3. It is envisioned to function as

a complement to the large scale FIRE facilities targeting traditionally connected regions. The test bed itself, the technology and the MEIS team’s skills constitute

the offer from MEIS to the FIRE Federation of test beds.

Details about the Slovenian DTN test bed and the federation offer are provided in N4C Deliverable 2.3 Integration Plan for N4C Test Beds with other

Future Internet Test Beds.

The document contains a general presentation of the DTN test bed developed by MEIS d.o.o. The document furthermore describes the test bed

topology, possible use cases, and hardware and software solutions.

The Swedish test bed continues as a Level 1 activity built on separate agreements with users/customers and test service providers.

Slovenian DTN Test Bed

Within the N4C project MEIS is running a permanent DTN test bed in Slovenia for the last 2 years. The test bed is suitable for running short testing campaigns (of perhaps a few days or a few weeks) and even more suitable for setting up essentially permanent operations– allowing long term testing of prototypes of new hardware and software. The topology of DTN test bed is presented on the following figure. Test bed currently consists of static nodes (4 meteorological, 2 radiological and 1 webcam) and dynamic nodes (2 car mules and 4 SymbioNodes based on USB storage devices).

Meteorological and other environmental applications were chosen to demonstrate the Slovene part of the DTN testbed capabilities in the N4C project. There were two different reasons for choosing these applications as the basis of the Slovene DTN test bed: to enable climatological and other environmental data collection from remote areas, and to have a test bed suitable for permanent testing of DTN and applications.webpage_11.png

These two complementary approaches helped us to examine a wide collection of problems related to use of DTN in real life. It was designed in such a way as to help to technically develop, test, and verify several aspects of possible usage of the DTN infrastructure. In principal for the further use of DTN the meteorological, radiological or bird photography applications can be replaced with any sort of application that delivers automatically produced technical data or another type of information source that makes it necessary need to transfer data in these remote and communication challenged areas.
