In bandwidth abundant optical networks it is important to develop design strategies that are not only cost effective but also able to account for the inherent characteristics of the optical transmission medium responsible for the signal quality degradation. With this objective in mind, the paper proposes a design algorithm able to determine an appropriate placement of regenerators in Grouped Routing...
We propose a novel impairment-aware multicast tree design algorithm for hierarchical optical path networks. The proposed algorithm consists of grooming wavelength multicast trees tailored to service-specific distributions that are developed based on the inclusive relationship and a joint optimization of waveband trees. 3R regenerator placement subject to an optical transparent reach limit constraint...
We assess the impact of a hybrid hierarchical optical path network that utilizes electrical cross-connects for intermediate grooming and 3R regeneration of wavelength paths. Simulation results proved that it offers up to 60% cost reduction.
