Since opnet is a network simulator, it's easy to see the effect of any enhancement you can imagine. But it seems to me that connecting Sidney to the network wouldn't be a bad idea.
I have a network scenario in opnet where there are three locations the headquarters is Liverpool and two other offices one in london and the other one in Chicago, there is ftp and http server in Liverpool which London and Chicago make use of remotely, each location have its email, printer and video/voice server, the cable used to connect all locations to internet is T1, Liverpool is connected internally with 10baseT, Chicago 100baseT and Sydney 10baseT and Sydney has more load. what do I add to the network to enhance it ?
