A Network simulator for QoS

[Ezzy]

Hello everyone,

I am working on my dissertation about QoS VoIP. However, the university has no license for OPNET or any other simulator. I have tried Cisco lab equipment, but again the university has no  UCK9 license to activate "telephony service" command. Any one can recommend a free network simulation tool or any other solution please? thanks, Ezzy

Hi

  GNS3 and Eve are those I know.

in addition to GNS3 and Eve ng (or EVE-ng) , check CML - Cisco Modeling Labs via DevNet sandbox for free or any other VoIP labs they have.
