| SAS/OR: The netWorks Application |
The telecom modeling facilities in the netWorks application were originally designed to investigate performance issues in connection-oriented networks, such as a telephone network. The focus was on simulating and measuring transmission impairments such as transmission delay, noise, and error rates [Bell Labs 1983] and the simulated traffic generation functions were fairly basic. The application has been enhanced to address issues of network capacity, reliability, and availability, and the traffic generators have been improved as well.
In a typical telecom modeling scenario you have various geographic locations with station equipment (telsets, faxes, and so forth) interconnected through a switched network. You create a model network in the drawing panel using telecom equipment models and then, using the Attribute palette, select the performance attributes you want to investigate in your simulation. You must also identify the paths through your model that are of interest; depending on the size and scope of your model network, a subset of paths may be more appropriate for your simulation than studying all possible paths. Once the path identification is completed, you can start generating simulated traffic over your model network and begin collecting data.
