DROPv2: energy efficiency through network function virtualization

Design and evaluation of algorithms for mapping and scheduling of virtual network functions

“…These include [2] which is a non-proprietary white paper authored by network operators to outline the benefits, enablers and challenges for NFV, [3] an Internet draft that discusses the problem space of NFV and [5] a reference architecture and a framework to enforce service function chaining with minimum requirements on the physical topology of the network. In addition, Clayman et al [21] describe an architecture that uses an orchestrator to monitor the utilization of infrastructure resources so as to place virtual routers according to policies set by the infrastructure provider, while DROP [22] proposes a distributed paradigm for NFV through the integration of software defined network [23] and information technology (IT) platforms. T-NOVA [24] outlines an architecture, which allows operators to deploy VNFs and offer them to their customers, as value-added services.…”

Cloud-based Wireless Network: Virtualized, Reconfigurable, Smart Wireless Network to Enable 5G Technologies

“…These virtual devices in the network will work as a physical device, and can achieve a variety of specialized functions without a specific device [36][37][38][39]. Currently, NFV mainly focus on the following issues.…”

Algorithms for advance bandwidth reservation in media production networks

“…NetFATE [133] proposes an orchestration approach for virtualized functions, taking into account the service chains needed by traffic flows and the desired QoE. In addition, other MANO frameworks and architectures have been proposed in [134], [135], [136], [137], [138], [139], [140]. However, there are still some open issues.…”

“…NFV will put InPs under even more pressure to manage energy consumption [138] not to only to cut down energy expenses, but also to meet regulatory and environmental standards. Topics with regard to energy efficient hardware which could allow reductions in CPU speeds and partially turning off some hardware components, more energy-aware function placement, scheduling and chaining algorithms, will be important.…”
