Protection and restoration strategies are critical to Optical mesh networks. Two are the most usual methods of the optical path protection. In the first method, the spare capacity is usually allocated as a "dedicated" resource where the backup capacity is allocated for the sole use of the connection or link. In the second method, it is associated as a "shared" resource, where the allocated backup capacity can be shared with other connections or links. In this paper, the first method will be examined in light of the finite differences. The latter provide two methods, the first is the linear function and the second is the polynomial function. The polynomial function is calculated by two methods. One is accurate and the other approximated. These methods are arithmetical and solve successfully the survivability problems. These methods are used for the verification of their results.

“…ITH the increasing demand for greater transmission bandwidths and the large variety of applications for which this bandwidth is used, it is of great importance to have networks capable of dynamic reconfiguration [1]. This enables the networks to be adapted to the changing requirements placed upon them by users.…”

Abstract-We use the frequency-resolved optical gating (FROG) technique to determine the pulsewidth and chirp characteristics of wavelength-converted pulses from a turbo-switch and asymmetrical Mach-Zehnder filter combination under a variety of operating conditions. The output pulses were found to be near transform limited and had a high tolerance to line rate and input power variations.Index Terms-High-speed optical techniques, optical frequency conversion, optical pulse measurement, semiconductor optical amplifiers, wavelength conversion.

One approach for accommodating traffic on a wavelength-routed optical network is to construct a virtual topology by establishing a set of lightpaths between nodes. To adapt to various changes in network environments, we propose an adaptive virtual topology control method, which reconfigures virtual topologies according to changing network environments, in IP over wavelength-routed wavelength division multiplexing networks. To achieve adaptability in the virtual topology control method, we focus on attractor selection, which models behaviors where biological systems adapt to unknown changes in their surrounding environments. The biological system driven by attractor selection adapts to environmental changes by selecting attractors of which the system condition is preferable. Our virtual topology control method uses deterministic and stochastic behaviors and controls these two appropriately by simple feedback of IP network conditions. Unlike current heuristic virtual topology control methods developed in the area of engineering, our method does not rely on pre-defined algorithms and uses stochastic behaviors for adapting to changes in network environments. The simulation results indicate that our virtual topology control method based on attractor selection adaptively responds to changes in network environments caused by node failure and constructs operational virtual topologies in more than 95% of simulation trials when 20% of nodes in the physical network fail simultaneously.
