What should be the model of a optimized ISP > network ( or PoP site) ? You want to optimize for the lowest monetary cost network that still allows you to meet all the SLA's you've negotiated. And this depends on what you negotiated - for instance, if the SLA specifies 3 9's of reliability, spending money to build a 4 9's network is cutting into your profits. Of course, if the SLA's are biased towards latency or bandwidth, you'll have to consider those. And remember that there usually isn't one right answer for anything but the most simple problems - almost always, some constraint will be placed on the solution. Often it's of the form "The salesdroid just promised XYZ", also known as the "Don't let your mouth write no check your router can't cash" syndrome. If it isn't that, it's a financial issue inside the company - there's always the network you *want* to build, which is almost never the network that your revenue stream will allow you to build....
