If a magic packet arrives and is addressed to the device's MAC address, the NIC signals the computer's power supply or motherboard to awaken. In computers capable of Wake-on-LAN, the NIC(s) listen to incoming packets, even when the rest of the system is powered down. This is an identifying number, built into each network interface controller (NIC), that enables the NIC to be uniquely recognized and addressed on a network. The magic packet contains the MAC address of the destination computer. 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.
