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.

If the computer being awakened is communicating via Wi-Fi, a supplementary standard called Wake on Wireless LAN (WoWLAN) must be employed. It is also possible to initiate the message from another network by using subnet directed broadcasts or a WoL gateway service.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. The message is usually sent to the target computer by a program executed on a device connected to the same local area network.

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 by a network message. A physical Wake-on-LAN connector (white object in foreground) featured on the IBM PCI Token-Ring Adapter 2
