* load). The major choice is a three way tradeoff between low-delay,
* high-reliability, and high-throughput.
* The use of the Delay, Throughput, and Reliability indications may
* increase the cost (in some sense) of the service. In many networks
* better performance for one of these parameters is coupled with worse
* performance on another. Except for very unusual cases at most two
* of these three indications should be set.
