Service Availability (SA) parameter is one of the key parameters of any Service Level Agreements (SLA), and there is a way to evaluate this parameter that proposed by ITU-T recommendations. However, due to the complexity of networks of service providers, this problem continues to be relevant. In this paper, an approach for evaluation of SA parameter is proposed. This approach considers the layered structure of telecommunication networks (primary and secondary networks), a network topology, and is based on the reliability theory. Test evaluation of the proposed approach shows its sensitivity to presence of back-up links and network topology and running time of network equipment.

Keywords:SLA, service availability, reliability theory, service provider.
