Riordan Manufacturing WAN Project Part II

Create a new project model in OPNET® OpenIT for the existing Riordan manufacturing WAN. Name your new model “Team_X” and replace the X with your team identifier.

 

Begin creating your model by creating an empty scenario. Choose “World” for the network scale. You will find some of the devices in the UOPX Palette that were copied when you installed the software and the rest in the existing palettes. Use the Visio® models from the IT section of the intranet as a basis for your model.

 

Share the model with your fellow students. Copy the files that start with “Team_X” in the op_models directory. (Note. You do not need the backup files that  have bk in the name and reside in the op_admin directory). Attach these files to a post in your team room.

 

Attach the finalized files to your assignment submission.

ITU Standards

Write a 200- to 300-word short-answer response to the following:
