Abstract :
This paper presents a study of dependability aspects of a switch architecture for optical burst switching based on tuneable lasers and array waveguide gratings. For this architecture, we carry out analyses of failure modes, alternative fault tolerance schemes and the relation between redundancy dimensioning and the dependability properties one might expect.
