The modern society has become dependent on different communication and information networks. The technical infrastructure relies on these networks. In spite of the growing dependence on the networks, the reliability and vulnerability of communication networks has not been analysed by using the tools of reliability engineering. In this paper, we aim at stating the problem of the communication network dependability. In order to do this, we identify the characteristics of communication networks, which may have an impact on the systems reliability. We propose reliability indicators on various levels of the system architecture. We discuss the possibility to develop reliability measures for the components, the network nodes and connections and functional units, limited parts of the network, and finally for the whole network. Furthermore, we discuss shortly the applicability of conventional reliability analysis methods in communication network reliability.
