Before revision:  We show in extensive numerical experiments that our solution enables the analysis of large-scale networks by reducing the computation time by several orders of magnitude in contrast to the optimization analysis. Moreover, in networks where optimization is still feasible, our delay bounds stay within close range, deviating on average by only 1.16\% in our experiments .
