In this paper, we defined the dynamic model to treat the problem of evaluation of reliability measures of a telecommunication network. We used two approaches, the first is based on the factoring method when the second is based on discrete events simulation techniques. We give some numerical results on the telecommunication network of Bejaia town.

nels in the future. Furthermore, teleservices process more Emerging telecommunication services use, store, or transmit sensitive personal data to form individual network services. We suggest an add-on approach to realize secure telecommunication services which saves the huge investments into existing network infrastructure of the ISDN. This is done by adding trusted runtime environments that co...

The hierarchical hub location problem is encountered three-level network that is applied in production-distribution system, education system, emergency medical services, telecommunication network, etc. This paper addresses the hierarchical hub covering problem with single assignment accounting for mandatory dispersion of central hubs restriction as a special case. This formulation with incorpor...

As the telecommunication world moves towards a data-only network environment, signaling, voice and other data are similarly transported as Internet Protocol packets. New requirements, challenges and opportunities are bound to this transition and in uence telecommunication architectures accordingly. In this time in which the Internet in general, and telecommunication networks in particular, have...

This contribution deals with routing of Multipoint connections in telecommunication networks using Eugenic algorithm. Telecommunication network is represented by undirected graph. Proposed algorithm uses matrix bit representation of individual.
