Simulate

#summary Chapter four of the Shanks User Manual. #labels Phase-Support

== 3. NETWORK SIMULATION == We have the network elements, failures that affect them and we put all of that on a scenario. What it takes to run a simulation?

To launch the simulation we implement a class that inherits from ShanksSimulation. This class must have a main method to obtain an instance of the scenario we have define, make its set up and perform the simulation step by step.

An implementation of this class present in code below. === 3.1. HAN-Model: Simulation === We are coming to an executable version of the example, now we need just to implement the class that allows us to run our simulation. Next we present the code lines of that class beofre explain it. ==== Textbox 6: HANModelSimulation.java ==== {{{ package es.upm.gsi.tsag.demo.simulation; import java.lang.reflect.InvocationTargetException; […]
