The magic packet contains the MAC address of the destination computer, an identifying number built into each network interface card ("NIC") or other Ethernet device in a computer, that enables it to be uniquely recognized and addressed on a network. WoL is implemented using a specially designed frame called a magic packet, which is sent to all computers in a network, among them the computer to be awakened. Principle of operation Įthernet connections, including home and work networks, wireless data networks, and the Internet itself, are based on frames sent between computers. In April 1997, this alliance introduced the Wake-on-LAN technology. In October 1996, Intel and IBM formed the Advanced Manageability Alliance (AMA). The WoL and WoWLAN standards are often supplemented by vendors to provide protocol-transparent on-demand services, for example in the Apple Bonjour wake-on-demand ( Sleep Proxy) feature. It is also possible to initiate the message from another network by using subnet directed broadcasts or a WoL gateway service. The message is usually sent to the target computer by a program executed on a device connected to the same local area network. If the computer being awakened is communicating via Wi-Fi, a supplementary standard called Wake on Wireless LAN (WoWLAN) must be employed. Wake-on-LAN ( WoL or WOL) is an Ethernet or Token Ring computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message.Įquivalent terms include wake on WAN, remote wake-up, power on by LAN, power up by LAN, resume by LAN, resume on LAN and wake up on LAN.

This change would allow the user to specify the grace periods based on the time it takes for a specific machine to boot/power-off and would prevent the state to bounce back for several seconds before getting effective. This grace period should be 0 by default for both operations to make this fix a non-breaking change. At the same time a grace perdiod (configurable separately for power-on and power-off) should be started before any ping operation is performed again.
The switch should instead always assume the performed action was successful (either turn on or turn off) and reflect that change in its state (like it happens if no host is specified). There is no way to know if the WOL packet successfully woke up a machine, but currently the switch assumes a failure by default which seems to be the way less common case. This clearly happens, because the state is exclusively determined by the underlaying ping sensor.
