Energy consumption in communication networks is ever increasing. The target of reducing the energy can be approached from different points: еnergy usage reduction of different hardware components, sleep mode, energy efficient routing and signalling protocol extensions.
Another interesting aspect in communication networks is that connections must be protected against failures. The backup resources are normally connected and powered on, which also contributes to the energy budget. Using Shared Path Protection (SPP) minimizes the protection resources by efficient sharing of wavelengths, regenerators and wavelength converters.
Furtheron signaling extensions that can reduce the energy usage by reducing the usage of electrical ports can be designed. In this paper, we use GMPLS extensions to integrate energyefficiency considerations into the network protection paradigm; and we use OPNET Modeler to evaluate our proposal.
