“…Energy profiles in various AR states in the presence of LPI primitives and the resulting optimal device energy profile [5] Network design and traffic-engineering decisions can exploit the full energy-saving potential of network devices using information of load-dependent energy consumption and energy profiles. In this respect, a recent standardised interface referred as Green Abstraction Layer (GAL), has been approved by ETSI (the European Telecommunication Standards Institute) [124]. GAL interface enables energy management protocols to consistently determine which power management capabilities are available at the data plane, their potential effects on both energy consumption and network performance, and how to interact with them.…”

“…It allows to a network admin running an energy-aware configuration which dynamically turn off not needed devices. The work in [166] proposes an ETE solution inside OpenFlow protocol, with the aid of the GAL (Green Abstraction Layer) [124]. This integration permits internal communication between network devices to interchange their power states.…”

Summary-Energy consumption of large-scale networks has become a primary concern in a society increasingly dependent on information technology. Novel solutions that contribute to achieving energy savings in wired networks have been proposed to mitigate ongoing and alarming climate change and global warming. A detailed survey of relevant power-saving approaches in wired networks is presented here. We give a special focus on carrier-grade networks. At first we perform a comprehensive study of communication infrastructures regarding energy saving. Then, we highlight key issues to enable green networks, ranging from network design to network operation. After that, we present the major contributors to power consumption in wireline networks. Afterwards, we survey, classify, and compare the main energyaware methods and mechanisms that are the most appropriate for improving the energy efficiency of carrier-grade networks.

“…Energy-efficient traffic engineering is a promising network level technique to manage the routing path and to disable as many Ethernet ports as possible without significant packet delay and loss. If a network level technique is involved, network-wide coordination, such as the green abstract layer (GAL) [31], is compulsory. The GAL provides advanced power management capabilities to decouple distributed high level algorithms from heterogeneous hardware.…”

Abstract:Energy efficiency is an important criterion in the design of next generation networks for both economic and environmental concerns. This paper presents an energy-efficient router that is able to dynamically adapt its routing capability in response to real-time traffic load, achieving energy proportional routing. The NetFPGA reference router, which operates at one of two frequencies (125 MHz or 62.5 MHz), requires a board reset to switch frequencies. We have modified the reference router to allow dynamic switching among five operating frequencies. Experiments with real traces indicate that, compared to the reference router, a 10% power reduction can be achieved through dynamic frequency scaling. When the router is further modified to support green traffic engineering and Ethernet port shut-down, power consumption can be reduced by 46% while maintaining the required quality of service. This allows the router to meet the instantaneous performance requirements while minimizing power dissipation. Similar results can be expected when these general power-saving principles are applied in future commercial routers.

“…Since traffic requests to cloud computing and data centers are explosively increasing, it is expected that the power consumption of the cloud computing will soar in the near future. According to [81] (GAL), which is a framework to manage energy efficient networks of the future [61], [62], [63].…”

“…In adaptive data center activation model, the system setting time is not a minor issue in terms of system delay. The inactivated devices keep in standby or low power idle states as described in [62], [63]. If the devices are under the low power idle state for power saving purpose, a longer system setting time will be required when the device is required to wake up.…”

I would like to dedicate this dissertation to my father Tae Eun Yoon, my mother Ok Rye Seo, my sister Seung Hee Yoon, and fiancee, Ha Neul Lee. I believe I could not be able to complete PhD degree without their support. Thank you for trust me and wait me for five years. I know it has been really long time and feel deep gratitude for their sacrifice. I also would like to express thanks to all my families and friends who support me.
