Abstract: In an evaluation method it is detected whether an operator k of at least a part of a communication network gets less than an agreed minimum number of resources/throughput or less than an agreed share of resources/throughput according to a sharing framework. In case it is detected that the operator k does not get less than the agreed minimum number/share of resources/throughput, it is determined that the sharing framework is not violated and this result is stored in a metric m(j). In case it is detected that the operator k gets less than the agreed minimum number/share of resources/throughput, it is detected whether the operator k has enough traffic to be served to fill the agreed minimum number/share of resources/throughput. In case it is detected that the operator k has enough traffic to be served, it is determined that the sharing framework is violated and this result is stored in the metric m(j).
