Analysis and evaluation of survivability of various configured communication networks

In this paper a new approach is proposed for analysing and comparatively evaluating communication network survivability under extreme conditions of the network elements. The approach is based not on the probability of network connectivity but on mathematical expectation of the number of survived connections. As the survivability of the network depends on its structural configuration (topology), the present work results in expressions for the calculation of mathematical expectation of the survived part of connections for various network configurations.
