said by jfmezei:DPI is not a network management solution, it is a service management solution which defines what types of uses of internet are to be allowed and what parts are not allowed. This is not an "engineering" decision, it is a management decision.
If congestion were a problem, Bell Canada would have delayed Sympatico 40% speed increases from 5 to 7mbps until the backbone was able to support it. That would have been an engineering solution to manage the network. The ADSL speed is the only variable that Bell can control under GAS tariffs. ISPs control how much AHSSPI capacity they purchase to support the type of uses their customers make at the speeds Bell as decided to supply on the ADSL loops.
Management at the application level is not network management, it is service management.
