In today's world energy conservation has become very important ever thing is going under some alternative methods in order to save the energy like architectures and some eco-friendly techniques. Now networks is very important in today's life every data is going through it only especially in LAN's energy conservation for switch is very important. Previous work on reducing energy consumption has primarily looked at either changing link rates or putting interfaces to sleep. Due to the unpredictable nature of traffic, the energy savings achieved have been modest, do not scale, and incur losses and delay. In this paper, the authors proposed many techniques so that they can conserve energy like Sleep, Awake, and Hibernate algorithms.
