Now a days ICT has powerful impact on economy and environmental conditions of the country. The principle of green networking gives idea to design a energy aware network. These networks focus on the energy reduction and consumption of unnecessary energy to save the environment. It is predicted that the global IP traffic will be approx 63.9 Exabyte’s per month in coming years .These increased bandwidth requires more bandwidth and it consumes large amount of energy and causes global warming too.
To reduce this global warming effect various power saving schemes are opted by the service providers that contributes to save the environment. In this scenario we develop a heuristic to choose the power efficient pre configured cycles (PEP- cycles) from the group of all cycles to minimize the effect of NP hard problem. The developed algorithm is used to achieve fast speed protection of optical network. The main aim of the algorithm is to reduce the complexity of the optimization and to resolve the complexity problem.
