This paper deals with an energy saving routing solution, called Energy Saving IP Routing (ESIR), to be applied in an IP network. ESIR operation is integrated with Open Shorthest Path First (OSPF)
The rapid development of communications networks facilitate our lives but bring severe energy consumption problems. As an emerging network structure, software-defined networking can
The continuous growth of traffic and the energy consumption of network equipments can limit the deployment of large-scale distributed infrastructure. This work aims to improve the energy
With BERT, network managers can rest assured that the fiber optic communications channel will be able to support these higher speed systems and applications. Let''s consider a typical fiber optic backbone
ABSTRACT In backbone networks, the line cards that drive the links be-tween neighboring routers consume a large amount of en-ergy. Since these networks are typically overprovisioned, se-lectively
In this study, we investigate the energy-efficient traffic engineering problem in hybrid SDN/Internet protocol (IP) networks. First, we formulate the mathematical optimization model considering the
AI Energy efficiency in backbone networks is critical as global Internet traffic is projected to reach 1.4 zettabytes by 2017. ICT consumes 2% to 10% of worldwide energy, with projections suggesting it
In recent years, green networking has attracted a lot of attention from device manufacturers and Internet Service Providers (ISP) to reduce energy consumption. In the literature,
But the sensors and the backbone network that send data to that server also consume electric power. Usually the wireless backbone elements are always turned on, which could incur a
The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval.
