Abstract :
Efforts to reduce power consumption in telecommunication networks follow in two mutually related directions - design of a more efficient equipment and development of energy-aware network control strategies and protocols. The paper presents a formulation of two-criteria traffic engineering problem, which takes advantage of energy saving capabilities in software routers. The first optimization criterion is the energy consumption, and the second one is the quality of service and service sustainability. Models and traffic engineering strategy were verified in laboratory experiments.
