Abstract

We propose an improved postponed lightpath teardown (PLT) strategy by introducing a lightpath splitting mechanism in multi-layer optical networks. Results show that the proposed strategy achieves higher utilizations of both wavelength-links and transceivers under different scenarios of load and transceiver number, and significantly reduce the blocking probability (CBP).
