Shofu, thanks for the suggestion.

Your scenario seems to contain only a single hop with the flows of
monotonically increasing latency bounds specifications.
I suggest that for a scenario to be effective in evaluating our queuing
solutions, the following requirements should be met.

1. The network should have a large enough diameter, such as more than 8
hops or so.
2. The network should have a complex topology including mesh or ring.
3. The flows should have TSpecs, including max burst size and average rate.
4. The flows should have RSpecs, which reflect realistic latency & jitter
bounds such as those of video, XR gaming, or industrial control loop.

My paper below has the simulation setup which meets these requirements.
If you are interested, please take a look.

Best regards,
