What is End-to-End QoS?

End-to-End QoS is a policy that ensures that all network components that exist between the endpoints of a network implement appropriate QoS mechanisms and do so consistently. This means that if your organization uses a service provider for network connectivity between your locations, it is not sufficient for you alone to implement proper QoS mechanisms. Your service provider must implement them as well.

When implementing end-to-end QoS, you should perform traffic classification and marking at every location in your organization where traffic originates. You should do this classification and marking as close to the source as possible, to eliminate the need for such efforts to become duplicated at various locations. You should also police unwanted traffic as close to the source as possible, too, as this is the most efficient means of handling it. Additionally, you should enforce QoS mechanisms upon any connections that exist between your equipment and the equipment of one of your providers.
