Network simulation software

detail Information about Network simulation software

1. Seminar On Network Simulation Software Presented By :- Kartik N. Kalpande

2. Introduction What is Network Simulation? “ Simulation is the process of designing a model of a real system and conducting experiments with this model for the purpose of either understanding the behavior of the system and/or evaluating various strategies for the operation of the system.”

3. Allow Us Model complex systems in a detailed way Describe the behavior of systems Construct theories or hypotheses that account for the observed behavior Use the model to predict future behavior, that is, the effects that will be produced by changes in the system Analyze proposed systems

4. List of Simulator Open Source Simulator: NS2 NS3 OMNET++ J-Sim etc..

5. List of Simulator cont.. Commercial : OPNET QUALNET 20-Sim AMEsim etc..

6. Comparison of different simulator Features Qualnet Omnet++ NS-2 OPnet J-Sim Language Supported Parsec/ C++ C++ C++/OTCL C++/Java Java License Commercial Open source Open source Commercial Open source GUI support Excellent Good Poor Excellent Good Time taken to learn Very easy Moderate Long Long Moderate Platform   Linux   Linux,mac-os,unix Unix,mac-OS Microsoft window Cygwin C,C++,Opnet modeler software   Mat lab Availability of analysis tool           Network visualization tool           Possibility to design and modify scenarios           Create trace files            

7. Application Areas Manufacturing/ Materials Handling Public and Health Systems Military Natural Resource Management Transportation Computer Systems Performance Communications

8. Advantages of Simulation Can be used to study existing systems without disrupting the ongoing operations. Proposed systems can be “tested” before committing resources. Allows us to control time. Allows us to gain insight into which variables are most important to system performance.

9. Advantages cont.. Cause-effect relations Exploration of possibilities. Diagnosing of problems. Identification of constraints. Visualization of plans.

10. Disadvantages of Simulation Training required. Interpretation of results required. Time consuming/expensive. Inappropriately used. Simulation results are sometimes hard to interpret.
