Salam Reza, You are asking an interesting set of questions, it might be easier to answer the over a phone call conversation (at least fro our perspective, being a small ISP/NSP ). I can write to you a lengthy reply, but am not sure if I will be able to convey to you the information properly.
The way you have posed the question, indicates to me that you are taking a particular view of a 'network', which is not the same view I hold. I am not sure if your view is more prevalent or our view as a service provider. Regardless I think it would make for an interesting conversation. Feel free to call me at your convenience. Regards.
