Abstract: |
In the multi-service requirement of the next generation of optical networks, differentiated services should be provided, and
the transmission quality of signal and the path reliability are two important parameters of service class differentiation.
A new dynamic routing and wavelength assignment (RWA) algorithm supporting service-differentiated provision, which takes account
of both requirements of the signal transmission quality and the path reliability, is proposed. The numerical results from
simulation show that the algorithm can not only overcome the impact of impairment on signal transmission quality and guarantee
lightpath reliability, but also offer the service-differentiated lightpath according to its class. |
