>>>>>> I know my language was strong but let explain why, First not all traffic behaves the same. Go back to my initial post on the differences between TCP and UDP. UDP by the nature of the protocol is more sensitive to things like packet loss, latency, etc. So in order to deliver UDP services reliably (ie most streaming services) some type of prioritization must occur. If not then video will be constantly buffering and VoIP calls will drop. The reason why there exist QoS policies is because engineers are try to work with the transport medium we have. Bandwidth is a limited resource and you have all these different types of traffic contending for the same resource. If people expect web browsing, YouTube, Mumble, Netflix, SFTP, all run efficiently across the wire then prioritization is a reality that will not go away. This is nature of modern networks where data, voice and video are all converged on the same media. The reason I used the language I did was b/c an engineer who does not understands this and actually thinks that 'all traffic' can be treated the same will actually bring harm to the network. He will be doing a great disservice to users he supporting all under the false notion of 'equality'.
