I’m leaning towards IntServ too, but I recall that it struggles with scalability, which fits the question.

I have a feeling it could be the Best Effort model, but I’m confused because it doesn’t really provide QoS at all.

I remember practicing a question like this, and I think the DiffServ model is more scalable, so it can't be the answer.

I think the IntServ model might be the right answer since it focuses on providing QoS, but I'm not entirely sure about the scalability part.

Best Effort is too basic, and FIFO doesn't really fit the description. I'm leaning towards IntServ or DiffServ, but I'll double-check my notes to be sure.

The DiffServ model seems like the most likely answer. It's designed for better scalability compared to IntServ, while still providing QoS services.
