Abstract :
In order to address the virtual optical network (VON) provisioning problem, VON mapping approaches, which include the power-aware virtual links mapping (PVLM) approach and the power-aware virtual nodes mapping (PVNM) approach, are developed to reduce power consumption for a given set of VONs. Results show that our proposed mapping approach, PVLM, greatly reduces power consumption and saves spectrum resources compared to PVNM for different line rates and mixed line rate in flexible bandwidth optical networks.
