The evolution of communication technologies results in continuously increasing capacities and higher concentration of traffic on relatively fewer network elements. Consequently, the failures of these elements can influence an increasing number of customers and can deteriorate the quality of service provided by the network.
The paper presents a modeling approach which is based on a simple two-state reliability model of the network elements taking into account the architecture of the transmission network as well as the transmission routes and the protection techniques implemented in the network. Using these information the network performance-reliability indexes including lower and upper bounds are derived. Finally, the application of the method is demonstrated with some realistic network reliability analysis results.
