Traffic Policy Questions

I’m trying to replicate a physical network infrastructure in a virtual environment and need to set the bandwidth and latency settings to match the physical environment. Looking at the traffic-policy settings, I seem to have several options available. Which option or set of options do I need to configure to limit bandwidth and add latency to my virtual networks?

I see limiter, network-emulator, rate-control and sharper (Along with a few others that don’t seem applicable). What is the correct approach?

Thank you!!
