Survivability schemes for dynamic traffic in optical networks

... decisions are made individually for each path rather than for the entire line Therefore, no signaling is needed in UPSR For instance, as shown in Fig 2.5(b), in the case of a cable cut, the tail-end ... While various survivability schemes can be employed at different levels, this thesis focuses on designing survivability schemes in the logical layer for dynamic traffic...
