Stochastic network calculus is the probabilistic version of the network calculus, which uses envelopes to perform probabilistic analysis of queueing networks. The accuracy of probabilistic end-to-end delay or backlog bounds computed using the elegant theory of network calculus has been always a concern. In this paper, we propose novel bounds based on Doob's maximal inequality for N-demisupermartingales to compute end-to-end probabilistic bounds which improve the existing bounds from network calculus. In particular, we show that reasonably accurate bounds are achieved by comparing the new bounds with the exact results from queueing theory for a network of M/M/1 queues.
