Hi Jinoo,

Thanks for your comments. The slides is updated.
For the topology envisioned in my mind is actually the same as what Toerless provided before. I think it may cover the simulation topology as shown in your paper.

Regards,
PSF

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,
Jinoo

Hi WG,

During the session, most people hope to have one or several common examples to evaluate various queueing mechanisms. 
I provided an initial example (see the attachement). 
Hope it can be helpful and welcome more examples with typical and real requirements can be added.


Regards,
PSF
