Paper Abstract

We propose an improved postponed lightpath teardown (PLT) strategy by introducing a lightpath splitting mechanism in multi-layer optical networks. Based on the original PLT strategies, this paper introduces a mechanism to split the unoccupied shortest lightpaths into shorter ones when the network operates in a steady state. Results show that the improved 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).
