The paper presents a new availability model and method of calculating the availability of optical fibre transmission network, which include weighting factors. Weighting factors are defined and classified on the basis of behaviour analysis of the actual fibre optic network in the event of failures. The aim of this paper is to achieve a realistic basis for further academic research by combining field...
The paper presents a new availability model and method of calculating path protected network availability, using the parameters which describe the impact of cable network construction on overall availability. Based on previous studies and analysis of data on real optical fibre network failures and physical layer configuration, we defined and classified weighting factors. Presented algorithm for availability...
In this paper, the impact of dependent failures of optical links on the availability of the optical network is analyzed using Monte Carlo simulation. Simulation is used because analytical approach to availability calculation is too complex when there are dependencies between failures. Availability model is described and used in two case studies: ring topology and several functional structures of two...
The paper provides an overview of the resilient schemes currently adopted in network architectures based on IP over Automatically Switched Optical Networks (ASONs)/Generalized Multiprotocol Label Switching (GMPLS) based optical networks, namely the Optical Internet. In addition it outlooks the raising challenges and possible solutions in implementing advanced resilient schemes capable of satisfying...
The paper provides a logical description of the link protection scheme implemented in the photonic transmission network. Description is based on the notion of transport entities defined on the link level, and extended by resilience domains. The domains are used to relate primary and protection transport entities, being the crucial information for the traffic rerouting after a failure occurs. The protection...
