It provides users with a way of specifying such networks and to simulate their behavior. The modular design of the system allows new modules to be added to the system with little effort.
Source code is provided so that interested users can modify the simulator to their own purposes.
Online documentation and source code are part of the distribution. The simulator takes as input a scenario , which is a description of network topology, protocols, workload and control parameters. It produces as output statistics such as the number of packets sent by each source of data, the queueing delay at each queueing point, and the number of dropped and retransmitted packets. For more details, please see the RealEdit home page . Digital Inc. This makes it unnecessary for users to download, compile and build the simulator in order to run simulations.
