Type of Software:
PROT=prototype, a complete package, with GUI and possibly some help
  

Descriptive Keywords:
peer-to-peer system simulator, peer-to-peer search methods, efficiency, organisation-oriented overlays
   

Potential Use and Applications:
eaSim is an easy to use event-based, time-discret, graphical java simulation and development environment for simulating the performance behaviour of search methods in peer-to-peer-architectures.
   

General Description:
The eaSim simulation tool is a time discrete, event-based peer-to-peer simulator based on DESMO-J, a framework developed by Page and Kreutzer (2005). Unlike other peer-to-peer simulators, eaSim follows a layered approach for simulating each layer separately and in combination. The state and the behavior of a peer are modeled independently to allow exchanging the search and routing behaviour. Wizards assist the user during the simulation process. Figure 11 shows the choice, configuration and editing options for element type based behavior. Predefined metrics can be activated and visualized directly at simulation time.
