An Approach using Demisubmartingales for the Stochastic Analysis of Networks [article]

Kishore Angrishi, Ulrich Killat
2012 arXiv   pre-print
The accuracy of probabilistic end-to-end delay or backlog bounds computed using network calculus has always been a concern.  ...  In particular, we show that reasonably accurate bounds are achieved by comparing the new bounds with the existing results for a network of M/M/1 queues.  ...  The main advantage of using network calculus to do performance analysis of networks is that the network calculus allows to model a network of nodes as a single virtual node.  ...
