We report our experiences on application development with the open source OpenAIS framework, which is an implementation of the standard Application Interface Specification (AIS) issued by the Service Availability Forum. Our focus is put on integrating existing (legacy) applications or services into the AIS framework (where the source code of these services(More)
This paper presents our results in the field of Model Driven Design (MDD) gained in dependable, distributed application development communicating over ad-hoc mobile networks. The context of the discussion is the Highly Dependable IP-based Networks and Services (Hidenets) research project. Our efforts involve (i) construction of the platform’s UML model,(More)
Using middleware implementations, instead of integrating the fault tolerance in the applications themselves, for providing stateful services highly availably has become the best practice in many industries including the telecommunication, computing and other areas. Robustness of these implementations toward user failures is essential for the overall(More)
This document contains an update of the HIDENETS Reference Model, whose preliminary version was introduced in D1.1. The Reference Model contains the overall approach to development and assessment of end-to-end resilience solutions. As such, it presents a framework, which due to its abstraction level is not only restricted to the HIDENETS car-to-car and(More)
This document contains refined descriptions of the HIDENETS test-bed implementations, which are used to show the feasibility of selected parts of the HIDENETS solutions when implemented on COTS components and to assess their impact on dependability and performance in an experimental laboratory environment. In order to focus on selected essential HIDENETS(More)

The main objectives of WP2 are to define a resilient architecture and to develop a range of middleware solutions (i.e. algorithms, protocols, services) for resilience to be applied in the design of highly available, reliable and trustworthy networking solutions. This is the first deliverable within this work package, a preliminary version of the resilient(More)
