Abstract :
As one of the key technologies in multi-domain optical networks´(MDONs) research, topology aggregation (TA) plays an important role in its security and scalability requirements. A novel TA algorithm applied to the MDONs with multiple quality of service (QoS) parameters constraints is proposed in this paper. The proposed algorithm captures the actual topology resources about the network more accurately via increasing a certain amount of control state information, which not only decreases the distortion effectively, but also obtains a good tradeoff between reduction and distortion. The simulation results show that the new approach achieves good performance in terms of the wrongly rejected ratio (WRR) and the crank back ratio (CBR), compared with the existing algorithms.
