Managed reach networks are networks that allow placing of regenerators in the main cities and at requested distances. These networks minimize the number of regenerators but need a routing approach able to establish the connections through regenerating nodes when the signal quality deteriorates. For this purpose, Impairment Constrained Based Routing (ICBR) is used. Considering that impairment related information is exchanged through signaling, the ICBR should be able to compute paths that guarantee a certain level of optical signal quality at the receiver. In this paper we propose an ICBR that is combined with a Routing and Wavelength Assignment algorithm. The proposed ICBR will be presented and used with two different impairments: the Polarization Mode Dispersion (PMD) of the fibers and the Amplified Spontaneous Emission (ASE) noise of the amplifiers. Savings in the number of regenerators is shown when the proposed ICBR is used instead of traditional routing algorithms such as minimum hop and shortest path. Dependence of the blocking probability on different parameters such as span length and OSNRmin is also demonstrated. |
