Prototyping
In this phase of the task, the work is concentrated on prototyping and refining the two core interfaces of the CONET testbed federation platform: Testbed Adaptation API (TA API) as common abstraction over the existing capabilities of the participating testbeds; and a Testbed Federation API (TF API) that leverages the services of the individual testbeds, exported through the TA API, to build a higher level abstraction over the federation aggregate.
- The complete code for the CONET testbed federation prototype is released as open source and available at the public repository http://cotefe.googlecode.com
- The front-end for the CONET Testbed Federation prototype is reachable at http://www.cotefe.net
Testbed Adaptation API
The prototyping of the TA API is performed on top of TWIST due to its mature remote access architecture and large popularity in the WSN community. To facilitate easy porting of the TA API prototype on other testbeds, the prototype has been further decomposed in two parts: a generic web server implemented in Python using the Django web framework, and a thin TWIST-specific wrapper that interfaces with the native TWIST API. The two parts of the TA API prototype currently interact using a generic XML-RPC bridge.
- The TA API prototype sever (for the TWIST testbed) is reachable at: https://www.twist.tu-berlin.de:8001
- Implementation of the TA API for the TWIST testbed
Testbed Adaptation Prototype for TWIST
The following table describes the mapping between the common testbed operations exposed in the Testbed Adaptation API and their implementation in the native TWIST API, via the XML-RPC bridge.

Testbed Federation API
In parallel, we have continued with the prototyping of the CONET Testbed Federation Server (CTFS) and its TF API on top of the Google App Engine (GAE) platform. Using the Django-Nonrel framework, the prototype implementation hides the complexity of the native GAE data store behind a convenient SQL-like API that increases the portability of the implementation and allows more easy migration to alternative cloud service providers.
- GAE Data Store entities containing the TF API resources
- Technology stacks used in the TF prototype
The existing frontend server and TF API prototype support the concept of federated authentication using the OpenID protocol. Further development of the common authentication support is postponed for Y4, pending a final adoption of the new OAuth 2.0 standard that matches our requirements much better than the OAuth 1.0 version, leveraged in the original design of the CTF architecture.
