本文将一个计算电路交换网中继线预留阻塞概率的模型推广到非整数中继线情况。如果模型要用于网络优化算法，则需要这种泛化，这些算法通常在实数上进行评估。首先提出了一个简单的扩展，并示出了数值不稳定的一些值的参数。一个递归的方法，然后解释，是强大的和有效的整数数量的保留干线和任意参数。最后将该模型推广到任意中继线数，并提出了一种高效、鲁棒的算法。
A model for computing the blocking probability in circuitswitched networks operating with trunk reservation is extended to the case of noninteger trunk numbers. This generalization is required if the model is to be used in network optimization algorithms, which are generally evaluated over the reals. A simple extension is first presented, and shown to be numerically unstable over some values of the parameters. A recursive approach is then explained that is both robust and efficient for an integer number of reserved trunks and arbitrary parameters. The model is finally extended to arbitrary trunk numbers, and an efficient and robust algorithm is proposed.
