When someone demands “net neutrality”, they usually mean that the network must not discriminate between applications being carried in IP packets; that identical transmission characteristics (throughput, delay, number of errors, etc.) are to be provided for all packets regardless of what is being carried in them. They claim (correctly) that this is not the case at present, that the network service provider is “throttling” certain applications, “slowing down” or “shaping” traffic (the correct term is “policing”) and that this, in their opinion, must stop.
This video tutorial explains Service Level Agreements, traffic profiles, transmission characteristics, and how Differentiated Services (Diff-Serv) is implemented to be able to provide different transmission characteristics for different kinds of traffic – the EXACT OPPOSITE of net neutrality.
