This paper studies the performance of call dropping policies for networks with stochastic capacity variation. Call-level simulation is used to compare the call blocking performance of 9 call dropping policies under a wide range of call workload and network capacity assumptions. Contrary to prior claims in the literature, our results show significant performance differences among dropping policies: the choice of an appropriate call dropping policy can significantly reduce call blocking, improving overall call-level performance in a stochastic capacity network. The effect is even more pronounced as the frequency and variance of capacity changes increase relative to the call workload characteristics. We propose an “equivalent capacity ” model to capture the dynamics of these interactions
