5 FINAL CONSIDERATIONS
Considering the increasing demand for ICT systems,
especially for networking services, it is even more im-
portant to set energy efficiency policies for these ser-
vices as basis for supporting Carbon free systems.
This paper presented how to refine an energy ef-
ficiency business policy down to the instance level,
considering the Policy Continuum’s five levels: Busi-
ness, System, Network, Device and Instance. The first
step was to use a methodological approach to prove
that it is possible to consider an energy-efficient pol-
icy in a network management system. The next step
is to develop an automated approach for the “Policy
Refinement Problem”.
This automated approach is important since the
business managers will be able to define business
policies that will be directly applied to the network,
devices and instances, making the business–IT align-
ment easier.
