All Implemented Interfaces:
```
public class SolverLQNS
extends Solver
                    
```
Solver interface to the LQNS external tool for Layered Queueing Network analysis.
SolverLQNS provides integration with the external LQNS (Layered Queueing Network Solver) command-line tool developed at Carleton University. This solver enables high-performance analysis of complex layered queueing networks through native C++ implementations.
Key LQNS integration capabilities:
- External tool integration via command-line interface
- LQN model serialization to LQNS XML format
- High-performance native solver algorithms
- Result parsing and integration back to LINE
- Support for complex software system models
Requirements: This solver requires the 'lqns' and 'lqsim' command-line tools to be installed and available in the system PATH. Tools can be obtained from: http://www.sce.carleton.ca/rads/lqns/

  - runAnalyzer
```
 void runAnalyzer()
```
    Executes the solver algorithm to analyze the model. This abstract method must be implemented by concrete solver classes.
  - runAnalyzer
```
 void runAnalyzer(SolverOptions options)
```
  - supports
```
 boolean supports(Network model)
```
    Checks if this solver supports the given network model. Default implementation returns true; subclasses should override to provide specific feature validation.
    
    Parameters:
    
    model - the network model to check
    
    Returns:
    
    true if the model is supported, false otherwise
  - getRawAvgTables
```
 Array<LayeredNetworkAvgTable> getRawAvgTables()
```
    Get raw average tables with detailed metrics for nodes and calls. This method provides more detailed metrics than getAvgTable(), including phase-specific utilization and service times, processor metrics, and call waiting times.
    
    Returns:
    
    Array containing [NodeAvgTable, CallAvgTable] with detailed metrics
  - defaultOptions
```
 static SolverOptions defaultOptions()
```
    Returns the default solver options for the LQNS solver.
    
    Returns:
    
    Default solver options with SolverType.LQNS
