A Feasibility Study for Power Management in LAN Switches
The authors examine the feasibility of introducing power management schemes in network devices in the LAN. Specifically, the authors investigate the possibility of putting various components on LAN switches to sleep during periods of low traffic activity. Traffic collected in the LAN indicates that there are significant periods of inactivity on specific switch interfaces. Using a summary sleep model devised for LAN switches, the authors examine the potential energy savings possible for different times of day and different interfaces (e.g., interfaces connecting to hosts to switches, or interfaces connecting switches, or interfaces connecting switches and routers).
