Abstract

In order to reduce the blocking probability and improve energy efficiency in IP over flexible bandwidth optical networks

it is necessary to reduce the occupation of spectrum resources and the number of working network equipment when building the optical channels. Network equipment configuration with flexible line rates can improve the energy efficiency. Therefore

we propose an energy-efficient approach based on mixed-line-rate equipment configuration. To evaluate the performance of the proposed approach

we introduce a traditional energy-efficient approach with two line rates for comparison. The simulation results show that

compared with the traditional energy-efficient approach in IP over flexible bandwidth optical networks

our proposed energy-efficient approach can effectively reduce the blocking probability and network energy consumption by at least 20% with improved network performance.
