Modeling and simulation of DiffServ scenarios with the NSDL framework

To provide an integrated and optimized management of network modeling and simulation tools is a complex task. Indeed, the underlying information structures used by these tools are, most of the times, very distinct and it is not simple to relate them. Moreover, the re-utilization of network descriptions and other network related data among tools is not current. The use of a standard data structure, or language, to describe data networks would promote the interoperability among network tools, providing the users with the possibility of applying new platforms and tools to validate their network scenarios. This work proposes the modeling and simulation of Differentiated Services networks based on the Network Scenario Description Language Framework.
