Method and network units for handling states

The embodiments herein relate to a method in a first network unit (101) for handling states in a network (100). The first network unit (101) is adapted to supervise power in the network (100). The first network unit (101) receives a work-load report from one or more of a plurality of second network units (105). The second network units (105) consume power. When the second network units (105) are awake and the workload is below a threshold, the first network unit (101) transmits a sleep request to at least one of the second network units (105) to change from awake to sleep. When the plurality of second network units (105) are asleep and the workload has reached or is above the threshold, the first network unit (101) transmits a wakeup request to at least one of the second network units (105) to change from sleep to awake.
