Hi all, For SC demonstration there is a need to have a centralised tool which will be able to show global reservation state and visualise the NSI demo topology. The first draft of such application will be required in about 4 weeks for Future Internet Week event held in Poznan between 24-28 Oct, where pre-SC NSI demo will be shown. During my discussion with Jerry Sobieski, we would like to propose the following specification for this visualisation tool: - A simple WebService needs to be implemented at network managers, which will allow to register event listeners (a WS addresses in fact), which will be the visualisation tool - NSI enabled network managers will notify listeners on all events regarding reservations (mostly reservation status change according to NSI reservation lifecycle model) - A visualisation tool will have a WS interface to receive the notifications from all domains involved in the demo - A visualisation tool will be able to show global status on the screen, possibly a topology map. It would be good if a reservation paths could be shown (either delivered by NSI implementations or "guessed" by a tool having knowledge on involved domains) The way of showing a view is a subject to discuss, it can be either a web page or an standalone application. The details should be clarified soon, at the beginning of the next week. As developers who are already involved in coding the NSI and their network managers, it will be best to find someone else dedicated especially for visualiser task. Jerry and I will appreciate any volunteering developers here, so please if you feel being able to write a simple tool to support with a little graphical interface for NSI demos, please rise your hand. In case of any questions, feel free to ask on mailing list or directly to me or Jerry.
