Abstract
AbstractThis paper is involved in the performance analysis of protection mechanisms utilized in common time division multiplexing-based passive optical networks. First, possible protection schemes for this kind of passive optical networks involved into the performance analysis are presented. This analysis is based on corresponding reliability diagrams and parameters used for the evaluation of the total network availability for each considered protection scheme. For evaluating possible migration scenarios related to protection schemes and comparing of protection possibilities of various passive optical networks, an appropriate simulation program must be prepared. Subsequently, the PON network availability evaluator is realized for obtaining relevant results appropriate for the performance analysis. The simulation program utilizes specific parameters for particular optical components utilized in a selected protection scheme and presents its resultant network availability. Values of considered parameters are changing according to the well-known data resources or specific network operator’s data. Finally, an evaluation of the total network availability for considered traffic protection schemes utilized in TDM-PON networks is included.KeywordsTDM-PON networksTraffic protection schemesPON network availability evaluatorPerformance analysis
