Abstract: Required capacity may be used in Connection Admission Control, Network Resource Management or for purposes of planning and dimensioning. From the well-known loss probability formula for the bufferless fluid ow model, an implicit formula for the required capacity for a given QoS per connection may be derived which turns
into a closed formula when it is evaluated in a special way. This formula, whose complexity is comparable to that of the original loss probability formula, allows for a
quick and exact evaluation of required capacity. Differences to other possibilities of required capacity evaluation are shown, and potential problems affecting the use of the formula are discussed. Finally, the suitability of the equivalent bandwidth in COST-242 for required capacity evaluations is demonstrated.
