[ns] IPv6-QoS and NS2 and NS3

[Bahareh_ntc@yahoo.com]

Dear all,
 
I am in the stage of choosing a simulator software however I need to consult with the experttes in this case and open up the discussion on IPv6 QoS..
 
Is any one of you aware of how much we can rely on NS2 for simulating the IPV6 QOS issues? is there so many limitations and bugs for develpping some new model in this environment (from your point of view)?
 
I  FORFOT TO ASK HOW ABOUT NS3? BECAUSE WHEN  iREVIED NS3, IT SEEMS THAT THEY ADD SOME COMPONENT FOR IPV6 ALREADY..ANY ONE HAVE ANY IDEA?
 
Thank you and looking forward to hear your valuable comments on this
 
 
 
Best regards
Bahareh
