chapter
Telecom operator networks are widely ramified and distributed communication infrastructures typically covering large geographical areas: Encompassing a plethora of active systems, they consume large amounts of electricity. Currently, general-purpose systems and virtualization concepts - that are known from information technology and data centers - are observed to diffuse into such telecom operator...

Current trends regarding telco network equipment evolution and changing paradigms in energy generation and power supply allow for a re-design of telco network production sites: On the one hand general-purpose hardware together with design ideas borrowed from IT data centers enter the telecom's world and on the other hand concepts of own and de-centralized electrical energy generation and power supply...
chapter
Conventional and virtualization-based implementations in operator networks are analyzed based on a realistic use case in terms of cost and energy efficiency. The results show advantages for the virtualization-based solutions as the systems' utilization as a key factor is improved.

The operation of large-scale telecommunication networks requires energy in different forms. Besides fossil fuels, district heating, and fuels to operate a vehicle fleet, the major energy demand for telecom operator networks is that of electricity. Electricity is needed to power the telecom network itself, the data center equipment, and to supply power to the equipment in offices and workspaces—where...
chapter
The impact of load-proportional systems on network energy consumption is analyzed based on time-varying traffic demands. With increased system load-proportionality network energy efficiencies improve, but significant amounts of energy have to be spent for upholding communication faculty on country-wide scales.

Energy consumption and energy efficiency of telecommunication networks are important for network operators regarding both, cost and sustainability aspects. Among several options, load-adaptive network operation—where the provided network capacity is coupled dynamically to the temporally fluctuating traffic characteristics—is a prominent and promising opportunity to improve network energy efficiency...
chapter
For operating large-scale telecommunication networks, considerable amounts of energy are necessary. Besides other forms of energy - like fossil fuels, district heating, and fuels for the vehicle fleet - the major network energy demand is that for electricity to power the network itself and other equipment in offices and workspaces. Large shares of network electricity are consumed by legacy network...

As a basis for meaningful simulation and optimization efforts with regard to traffic engineering or energy consumption in telecommunication networks, suitable models are indispensable. This concerns not only realistic network topologies but also models for the geographical distribution and the temporal dynamics of traffic, as well as the assumptions on network components and technology. This paper...
chapter
The energy-saving potential of load-adaptive operation principles for fixed operator networks is evaluated based on realistic network data for current and all-IP network equipment distributions. Overall energy savings with support of load-adaptive operation of below 10% for current and of around 50% for platform-consolidated networks are obtained.
chapter
Load-adaptive network operation is a promising opportunity for improving the energy efficiency of telecommunication networks. Besides the load-adaptivity of the telecommunication network elements also the supporting central office equipment like uninterruptable power supplies and HVAC (heating, ventilation and air conditioning) systems is important for overall network-site energy efficiency. The power...
chapter
The impact of broadband access network migration on the power and energy consumption is studied by establishing an analytic migration model. The results show that power-aware strategies are necessary for efficient broadband access network migration.
chapter
The energy consumption of telecommunication networks is forecasted over approximately a decade. The results show a high energy consumption share associated with the home networks and an overall growth if no countermeasures are taken.
chapter
The energy consumption of a telecommunication network increases, but at a reduced slope compared to the assumed traffic volume increase. The major energy consumption portion shifts from access to backbone networks with rising traffic volume.
