Methods for physical impairment constrained routing with selected protection in all-optical networks
In this paper, we investigate the problem of survivable all-optical routing in WDM networks
with physical impairments. One of the recent key issues in survivable optical network design …

Physical impairment constrained routing: Implicit signal regeneration via traffic grooming?
T Cinkler - 2013 15th International Conference on Transparent …, 2013 - ieeexplore.ieee.org
In this paper we present the idea to use the grooming-capability of two-layer networks not
only to better handle traffic, but also to implicitly regenerate physically impaired optical …

Selective protection for all-optical physical impairment constrained routing
In optical networks, according to the latest tendencies, the goal is to route all demands in all-
optical way. However, in the near future, this will still not be possible due to technical …
