....A preplanned survivable network, on the opposite, because of the rigid association between protection resources and working lightpaths, is not able to face an unknown number of simultaneous faults. Some works analyze the effects of multiple failures on WDM network with preplanned protection [14,34] and complex preplanned protection techniques are under study that are able to recover some simultaneous failures for simplicity we will not consider these events any more in the rest of this paper. Provisioning, however, suffers the disadvantage of not being completely safe: in fact there is no ....

....integrity, but that qualitative recognition does not directly help a service provider know what Service Level Agreements (SLA) can be safely offered. For ring based networks, some recent work has provided relatively thorough and exact mathematical models for quantification of path availability [1][2][3] but for mesh restorable networks the problem of availability analysis, and the relationship between availability and network capacity is not as well understood. A. Restorability, Reliability, and Availability There are several ways in which the reliability of a network or service can be ....

....class would enjoy availability superior even to that provided by 1 1 diverse APS by virtue of withstanding almost all dual failures (as well as all single failures) II. PRIOR LITERATURE The analysis of service path availability in ring based networks has recently been looked at in some depth [1][2][3] In contrast the availability analysis of mesh restorable networks is not as amenable to a detailed analytical approach and has consequently usually been approached with significant simplifying approximations. The problem is that the flexible nature of a meshrestorable network, its routing ....

....mesh networks in a bi objective sense, i.e. for max(R 2 ) subject to (min capacity for R 1 =100 ) Accordingly recent interests have evolved past the problem of restorability design itself, to quantifying the availability of services through such fully restorable networks. Some recent work [4,5,6] considered ring based networks in this light. A closed form model is provided in [5] and augmented in [6] for the availability of a path through a ring based network, including all details of two failure combinations and dual ring interconnect arrangements. Related work in [13] has also ....
