The paper presents analytical and simulation
availability models for evaluation of optical node availability.
Analytical models are developed for six ROADM (reconfigurable
optical add and drop multiplexers) architectures. Availability /
cost figures are calculated, compared and discussed. For one of
ROADMs simulation model is created and Monte Carlo
simulation of times to failure and times to repair is carried out. A
new measure k-out-of-n availability of a node is introduced.
Analytical and simulation availability figures are compared. The
possibility of simulation model application to other node
architectures is discussed.
