Due to the lower channel utilization in conventional wavelength-routed networks, TDM technique is implemented on top of WDM to achieve a WDM-TDM network. RWTA problem in WDM-TDM networks is discussed. With the idea that assigned time-slots of one session can be distributed in multiple different wavelengths and the objective of minimizing network blocking probability, a RWTA algorithm called MUMD was proposed for dynamic traffic in mesh single-fiber networks. Then we demonstrate the performance of the proposed MUMD algorithm through numerical simulation. The results show that MUMD can efficiently optimize the network blocking performance, thereby optimize the resource utilization.

Topology aggregation is very important for multi-domain network. To deal with wavelength and timeslots constrains in multi-domain WDM-TDM networks, a topology aggregation scheme is proposed in this paper. The proposed scheme is based on asymmetric star with bypasses structure and comprehensively considers the information of multi-path between each border nodes pair. Results show that our proposed scheme obtains a better tradeoff between information accuracy and information reduction.

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.
