Reliability evaluation of communication network is the precondition of researching how to provide various traffic QoS (quality of service) guarantee. This paper presented an evaluation method for WDM (wavelength division multiplexing) optical layer's connectivity reliability. First, we calculated all the minimal path sets of source-destination node pairs in the network using optimized node-traversal...
We propose a probabilistic characterization of network traffic. This characterization can handle traffic with heavy-tailed distributions in performance analysis. We show that queue size, output traffic, virtual delay, aggregate traffic, etc. at various points in a network can easily be characterized within the framework. This characterization is measurable and allows for a simple probabilistic method...
