Abstract
SSFNet is a Java-based discrete-event package for network simulation. The aims of this session will be (1) to show, from the perspective of the network modeler, how SSFNet is used, and (2) to give examples of what types of problems can explored with it, with a particular emphasis on routing issues.

There will be a concise general introduction to the simulator itself, including a look inside at its organization and structure, as well as an overview of the Domain Modeling Language (DML) used to build models. Following that will be a more in-depth examination of the component models included in SSFNet, particularly the BGP inter-domain routing protocol package. As a concrete example, we'll examine how SSFNet has been used to study the distributed convergence properties of BGP.
