| 520 | |a As the network is converting to transparent optical networks, the impact of physical layer impairments on transmission performance can't be ignored. The impairments will decrease the quality of signals. To find a lightpath with high quality of transmission (QoT), this paper adds impairment constraints to the routing and wavelength algorithm based on wavelength rotation graph (WRG-RWA) and proposes impairment aware WRG-RWA algorithm. The constraints consider amplified spontaneous emission noises and polarization mode dispersion which are the most important liner impairments. The new algorithm estimates the impact of the impairments after the route is selected, and selects another route when the previous one fails in comparing with the constraints. By simulating, the new algorithm has preferably improvement on blocking probability and wavelength efficiency by contrast with the WRG-RWA algorithm and the impairment aware FF algorithm. The simulation results show the new algorithm can effectively decrease the blocking probability of transmission and improve the performance of optical networks. | ||

Wavelength Rotation Graph Algorithm Based on Physical Impairment Constraints in Optical Networks |
| abstract |
As the network is converting to transparent optical networks, the impact of physical layer impairments on transmission performance can't be ignored. The impairments will decrease the quality of signals. To find a lightpath with high quality of transmission (QoT), this paper adds impairment constraints to the routing and wavelength algorithm based on wavelength rotation graph (WRG-RWA) and proposes impairment aware WRG-RWA algorithm. The constraints consider amplified spontaneous emission noises and polarization mode dispersion which are the most important liner impairments. The new algorithm estimates the impact of the impairments after the route is selected, and selects another route when the previous one fails in comparing with the constraints. By simulating, the new algorithm has preferably improvement on blocking probability and wavelength efficiency by contrast with the WRG-RWA algorithm and the impairment aware FF algorithm. The simulation results show the new algorithm can effectively decrease the blocking probability of transmission and improve the performance of optical networks. |

The new algorithm estimates the impact of the impairments after the route is selected, and selects another route when the previous one fails in comparing with the constraints. By simulating, the new algorithm has preferably improvement on blocking probability and wavelength efficiency by contrast with the WRG-RWA algorithm and the impairment aware FF algorithm. The simulation results show the new algorithm can effectively decrease the blocking probability of transmission and improve the performance of optical networks. |

The impairments will decrease the quality of signals. To find a lightpath with high quality of transmission (QoT), this paper adds impairment constraints to the routing and wavelength algorithm based on wavelength rotation graph (WRG-RWA) and proposes impairment aware WRG-RWA algorithm. The constraints consider amplified spontaneous emission noises and polarization mode dispersion which are the most important liner impairments. The new algorithm estimates the impact of the impairments after the route is selected, and selects another route when the previous one fails in comparing with the constraints. By simulating, the new algorithm has preferably improvement on blocking probability and wavelength efficiency by contrast with the WRG-RWA algorithm and the impairment aware FF algorithm. The simulation results show the new algorithm can effectively decrease the blocking probability of transmission and improve the performance of optical networks.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Walter de Gruyter Online Zeitschriften</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">routing and wavelength assignment</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">amplified spontaneous emission</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">polarization mode dispersion</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">wavelength rotation graph</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhao,, Jijun</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li,, Wei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang,, Shuguang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Guo,, Kun</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhao,, Wenyu</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of optical communications</subfield><subfield code="d">[S.l.] : De Gruyter, 1980</subfield><subfield code="g">33(2012), 3 vom: 25.
