Certainly you could choose to structure the procurement however you see is most appropriate. I'm not sure about the statistics you've outlined. It's the first I've heard of them, so I'm a little caught off guard. I'm not sure if they're true.
You say bandwidth and non-bandwidth. I am going to interpret your statement as saying the wide area network is provided by the telecommunications service providers, and when you get inside the building, the network that connects, I'll call it “from the basement”, where we might terminate our service going onto whatever floors the clients might be on, is normally provided by the client. Whether that's provided by SMEs or not.... In fact, my experience is that our customers would provide those components. So our customers would buy many of the networking components that are inside a building. Our customers would generally contract out the cabling of the building. Bell Canada does a lot of cabling for the Government of Canada in Ottawa. We subcontract that out to SMEs here in Ottawa.
Then the question is how you deliver service on an end-to-end basis. Your experience as the user of a computer, going to the Internet or accessing whatever application you're looking to access, is an end-to-end experience. You can't break it up into pieces. So the challenge is how you manage that, on an end-to-end basis, effectively and efficiently.
