“…These algorithms above all are based on multi fibers optical networks. In [7], the authors report a dynamic RWTA algorithm with complete switching capability in time domain. But for recent WDM-TDM networks the routing nodes without wavelength converters and time slots interchangers maybe be more applicable.…”

All-optical WDM networks are the most promising candidate for the next generation wideband backbone networks. To improve the utilization of wavelength, TDM technology is introduced into it. The routing, wavelength and time-slots assignment (RWTA) problem was studied in such time-space switched networks. A new adaptive algorithm was proposed which adopt adaptive network link weights and distribute slots of the session request on multiple different wavelengths adaptively with the remainder resource of the network. The effectiveness of the proposed algorithm is demonstrated by simulations and results show the better performance.

In this paper, the effect of holding time awareness on the process of time slot assignment in WDM-TDM is considered. Use has been made of Markov model in order to predict the wavelength congestion. A routing algorithm is developed based on the Markov modeling. The results are compared with existing algorithms--ASP, WSP and OTGA. Validation results have shown that the performance of the system is significantly improved in terms of bandwidth blocking ratio, network utilization and fairness.
