1. Distributed Object System Final Presentation

2. Agenda Project Goals Solution Strategy System Architecture

3. Project Goals Develop a distributed system for performing time-consuming calculations. Load Balancing support. Fault Tolerance support. Working with.Net Framework. Learning C# programming language.

4. Description A distributed system which consists of: WWorker Objects – objects performing any kinds of calculations. ““DosAgent” – a service that runs on every participating computer in the system and hosts worker objects. DDosAgent hosts “running” objects as well as “sleeping” objects. SSleeping objects are objects which are running on some other DosAgent on some other machine. DDosConsole – a GUI application, presents all running objects in system and gives control on running objects.

5. Description – cont. DosAgent: AA command line application running on all computers in the system. RReceives running objects from all other participating machines every T seconds and stores them as “sleeping” objects. IIf the operation failed the remote service is considered down and a failure treatment is issued. FFailure treatment restarts all “sleeping” objects originating from the dead service, on the least utilized machine in the system.

7. Description – cont. DosConsole: GGUI application. EEstablishes connection to a specified machine in the system. PPresents a list of objects “running” and “sleeping” on a specified machine. LLaunches new objects in to the system. KKills running objects in the system.
