“…More complicated protection techniques would allow recovery of simultaneous and independent multiple-link failures affecting both the working and the protection lightpath of a w/p pair. Multiple-failure recovery [19] greatly improves (by orders of magnitude) the connection availability [18], but on the other hand it requires a much higher network deployment cost. We will show later in this paper that, if we consider only internal failure causes, single-failure recovery is more than sufficient to meet the five-nines availability target usually demanded by customers at affordable deployment costs.…”

Abstract-A design technique for reliable optical transport networks is presented. The network is first dimensioned in order to carry a given set of static protected optical connections, each one routed maximizing its availability. The network can be further optimized by minimizing the number of fibers to be installed, while keeping a control on connection availability, which can remain the same or decrease by a prefixed margin factor. Design and optimization algorithms are provided for networks adopting dedicated and shared path-protection. The optimization approach is heuristic. Results obtained by applying the proposed technique to two casestudy networks are shown and discussed. These two case-study experiments are carried out exploiting a realistic model to evaluate terrestrial and submarine optical link availability.Index Terms-Deterministic network calculus, mathematical programming/optimization, system design.
