Comment QoS and net neutrality are the same issue... (Score 1) 66
What you have just described gives an artificial advantage (or disadvantage in the case of bittorrent) to managed protocols, discouraging innovation. A neutral network should not discriminate based on packet contents whatsoever. It is fundamentally impossible to fairly classify traffic, because there will always be unknown traffic and lack of agreement on priorities. In some cases, encryption may even prevent classification; why should those packets suffer? The only place where QoS is both functional and useful is on a customers own connection, where they set priorities among their own traffic.
Beyond that, an ISP has no business discriminating based on address or packet contents. The moment that is allowed, ISPs game the system. As seen, they invest in smart hardware capable of culling unwanted traffic rather than adding capacity, which inevitably results in a more congested network. This devalues the network for all non-priority traffic. There is exactly one good solution: add more capacity when necessary. This is the simplest, least expensive, and perfectly fair. It also ensures that there will be an excess of capacity available for innovative new protocols and uses.
