OPNET WiMAX Simulation

[DoruBalan]

Hi, people! I'm new here, and i registered to request your help, if possible.

First of all, I need to simulate mobility in WiMAX networks using OPNET Modeler 14.5. I did some research on the Internet and I found some topologies, but the problem is there are a couple of links in the topology that I do not know from where to take them.

You can find in the attachment such a topology. I'm asking you guys, which types of links in OPNET are the blue one (between MS and server) and the yellow ones (between BSs and Cloud)

Thanks for your help!
