Conclusions
We used OPNET simulation tool to demonstrate the performance of IPv6-over-ATM network.
OPNET standard ATM source, switch, and destination node models were modified to map IPv6 ToS into ATM service categories.
We simulated an IPv6-over-ATM network and measured end-to-end packet delays.
Simulation results indicated that IPv6-over-ATM may provide better service guarantees than IP alone.
