A detailed survey of approaches reducing energy consumption of core networks is
presented in this paper. We consider a multilayer architecture, in which the optical layer can …

As Internet traffic is estimated to substantially grow in the near future, one of the most
challenging issues will concern the reduction of its power requirement. For the core/transport …

Core networks offer high capacities, thanks mainly to the optical technologies they utilize,
but they consume a non-negligible amount of energy. The traffic volume in metro and core …

The tremendously large number of increasing Internet protocol (IP) packets call for quality of
service (QoS) guaranteed packets transmission with low-delay, high throughput, and high …

With the global Internet traffic continuously growing, network operators face more and more
challenges related to the management of their networks. Efficient utilization of the available …

To improve the energy efficiency of optical networks, strategies and technologies should aim
at ensuring a (low) power consumption proportional to the network utilization. To achieve …

With the rapid growth of traffic volume in telecom networks, a larger amount of network
equipment with higher capacity and enhanced processing speed is required to …

As global internet traffic continues to increase, network operators face challenges on how to
efficiently manage transmission in their networks. Even though attempts are underway to …

Load adaptive energy saving schemes for backbone IP networks use dynamic transport
circuit services to adapt the active network resources to the current traffic demand in order to …
