SOA over disadvantaged grids experiment and demonstrator

The objective of the IST-090 group is to investigate challenges of SOA applications in disadvantaged networks. The group studies possible solutions that can improve the overall efficiency of information dissemination when facing different disruptions. This paper presents lessons learned from the real-life experiment and demonstration that was carried out by IST-090 group members during the MCC 2011 conference. We evaluated several solutions, namely the WS-DDS interface, the DSProxy, the Mist protocol, and ESBs that were used as SOA solutions enabling efficient information exchange in a disadvantaged environment. The experiment was preceded by separate tests of each solution. However, in the combined scenario, the aim was to evaluate the interoperability of these solutions and define a long-term plan for either their application in operations or for further functionality development. The paper gives an overview of the solutions we investigated, presents a rough model of the network environment used, and discusses the results observed and the lessons learned.
