Ports

Port type	Java name	Port Name	packet type	Associated Variable	Intended connection
Input ports:
	inport	IN	String	RouterSlip	Loop Module
Output ports:
	outport	OUT1	String	RouterSlip	DotModule or End_of_loop

Synopsis

1. Process Routing Slip
2. Write initial.txt file
3. Write const.txt file
4. Run Dot
5. IF (return value==0) Update values of the design variables and update values of the link variable(s)
6. IF (return value==0) send updated Routing Slip to outport ELSE send "error" to endPort

Details

Process Routing Slip

1. Split the incoming string by " ". It is expected to have at least two elements; if not set returnValue to -1 (prohibiting the execution of the rest of the module)
2. The first is the identifier of the Dot instance: system. Convert it to integer; if this fails, set returnValue to -1 (prohibiting the execution of the rest of the module)
3. Update slip by calling SystemStatus.updateRouterSlip(String[]) which removes the fist element and concatenates the remainding element into a single String.

Write initial.txt

requires improvement

1. creates three Vectors<String> to store lb, initial value, and ub for each design variable
2. uses hardwired values for lb=0.0 and ub=10.0
3. the initial values are taken by invoking Strong iv[] = SystemState.getSubsystemVaraiblesValues(system)
4. write file using FileUtil.writeInputFile(configuration.systems[system]+"/initial.txt", lb, initvalues,ub), where initvalue is a Vector converted from String[] iv

Write const.txt

requires improvement

1. write file using FileUtil.Values2File(SystemState.getConstantValues(system),configuration.systems[system]+"/const.txt");
2. write to stdout values of SystemState.lambda, SystemState.W, and SystemState.link_up which is wrong

Run Dot

1. Dot myDotRun = new Dot(system)
2. returnValue = myDotRun.runDot

Update Design Variables and Link Variables

1. Vector<String> myOutput = FileUtil.getDotResults(configuration.systems[system]+"/result.txt")
2. convert Vector myOutput to String[] x
3. SystemState.updateSubsystemVaraibleValues(system,x)
4. SystemState.updateLinkVariables(system) which requires an improvement
