First, bandwidth is limited. It's whatever download and upload you sign for. Second, there is no such thin as "full speed access to Netflix" or whatever. It's limited by your own bandwidth at least. Third, when you pay for an internet access, you pay for a public IP and associated bandwidth, so you can send and receive as much IP packet as your bandwidth will allow you, no matter the provenance or destination. In practical terms, your ISP will be connected to other operators (either other ISPs, or transport/backbone operators), with peering agreements (data flows freely in both directions at no charge), or pricing schemes where the sender pays the receiver for the privilege of having the data transmitted. What your ISP will not have is a direct connection to each and every service out there. They don't have to update their infrastructure every time a new web site comes up. As such, access to Netflix, Youtube, or http://loup-vaillant.fr are not separate services. ISPs that treat access to particular web sites as separate services are just plain lying. The real "separate service", for which they actually spend money, is the throttling/filtering/censoring infrastructure they have to put in place to charge different web sites differently. Text book malicious features, not unlike DRM. A final note about bandwidth: operators tend to bill themselves to the 95th percentile of instantaneous bandwidth spend in the last month. Spikes cost as much as a flood. Because in practice, what matters is how much bandwidth you expect the other operator to sustain —because it determines how much they need to spend on infrastructure. Because of this, is it perfectly legitimate for a user to max out her bandwidth, continuously throughout the month. ISPs should calibrate their network, and bill, accordingly. |
Very rarely a low latency link. (like VoIP/real time specialized services)
