Which meaning of QoS are you using? http://en.wikipedia.org/wiki/Quality_of_service

The second definition there is

In the field of computer networking and other packet-switched telecommunication networks, the traffic engineering term refers to resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. For example, a required bit rate, delay, jitter, packet dropping probability and/or bit error rate may be guaranteed. Quality of service guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications such as voice over IP, online games and IP-TV, since these often require fixed bit rate and are delay sensitive, and in networks where the capacity is a limited resource, for example in cellular data communication.

If that is the definition you are using, then how do you define getting the "best result" for QoS ? The required QoS is either achieved or it is not. If it is not achieved, then the network is oversubscribed or underequiped and you have a failure of the end-to-end resource allocation protocol such as RSVP
