Configuration of network management for energy efficiency in optical transport networks using GMPLS and OBS techniques

The suboptimal distribution of the traffic load over the high-speed optical network channels results in poor overall channel utilization and leads to the increased energy consumption. This means that configuration of the network management system including traffic engineering protocols and traffic management mechanisms may have indirect but significant impact on the overall energy efficiency of the particular optical transport network setup. Therefore, we aim in this paper to estimate how energy efficiency of the optical transport network depends on the configuration of the management protocols and mechanisms deployed into the GMPLS and OBS technologies. In addition, we analyze particular configurations of specific mechanisms those allow to increase energy efficiency of the optical transport network without compromising the parameters of the quality of service (QoS).
