Routing technologies are discussed in this dissertation with the goal of improving the network availability. The “highly available Internet” is defined as the Internet with functions to forecast and control the network availability. An implementation strategy to approach to the highly available Internet and to the Dependable Internet is described. This dissertation provides a routing simulator ...

In the design of Wireless Mesh Networks (WMNs), one of the fundamental considerations is the reliability and availability of communication paths between network pairs in the presence of node failures. Reliability and deployment cost are important and are largely determined by network topology. In fact, adding redundant network components increases the reliability of a network, but also increase...

A method for assessment of reliability of the network is developed, which uses the features of the fault tree analysis. The method is developed in a way that the increase of the network under consideration does not require significant increase of the model. The method is applied to small examples of network consisting of a small number of nodes and a small number of their connections. The resul...

It is known that a certain case of the all-terminal network reliability can be computed via the Tutte polynomial which is an invariant in graph theory. Recently, we have proposed a new approach of computing the Tutte polynomial of a graph of moderate size [9]. In this paper, by using it we analyze computation method of the general all-terminal network reliability and two-terminal network reliab...
