Computers are generally started with the power on/off buttons. But in some cases, we may need to boot or start the computer from remote by using different techniques. Wake On LAN is a method that can start the computer from the network.

通常使用电源开/关按钮启动计算机。 但是在某些情况下，我们可能需要使用不同的技术从远程启动或启动计算机。 LAN唤醒是一种可以从网络启动计算机的方法。

什么是局域网唤醒？ (What Is Wake On LAN?)

Wake On Lan (WOL) is ea feature provided the network interface card and motherboard in order to boot a system over a network connection by sending special package which is called as Magic Packet. The magic packets contains the remote system NIC MAC address where the remote system NIC is only listening to the network in low-power mode even the system is powered down. When the NIC receives the magical packet the NIC will signal the computer power supply or motherboard to wake-up or boot the system like pressing the power button.

局域网唤醒(WOL)是一项功能，它提供了网络接口卡和母板，以便通过发送称为Magic Packet特殊程序包通过网络连接来引导系统。 魔术数据包包含远程系统NIC MAC地址，即使系统断电，远程系统NIC也仅以低功率模式侦听网络。 当NIC接收到神奇的数据包时，NIC将向计算机电源或主板发出信号，以唤醒或引导系统，就像按电源按钮一样。

魔术包(Magical Packet)

Magic Packet will trigger the start of a system remotely. Magical packet is a broadcast frame which works on OSI Layer 2 where it contains the remote system MAC address and FF or 255 values for data.The first 6 bytes contains “FF FF FF FF FF FF” value and then the MAC address of the target system by repeating 16 times.

Magic Packet将远程触发系统启动。 魔术包是在OSI第2层上工作的广播帧，其中包含远程系统MAC地址和FF或255个数据值。前6个字节包含“ FF FF FF FF FF FF FF”值，然后是目标的MAC地址系统重复16次。

In order to trigger the Wake On LAN features the following requirements should be met by a Magical Packet.

为了触发局域网唤醒功能，魔包必须满足以下要求。

• Requires the destination or target system/computer MAC address.需要目标或目标系统/计算机的MAC地址。
• May require the SecureOn password.可能需要SecureOn密码。
• As broadcast mechanisms there is no confirmation about the Magical Packet delivery by the remote target system.作为广播机制，没有关于远程目标系统传送魔术包的确认。
• The magical packet is only transmitted inside the Local Area Network and can not be routed outside of the current network不可思议的数据包仅在局域网内部传输，不能路由到当前网络之外
• The NIC should support the Wake On LAN to boot a computer remotely.NIC应该支持Wake On LAN来远程引导计算机。

局域网上的什么软件列表 (What On LAN Software List)

局域网唤醒支持(Wake On LAN Support)

Wake On LAN features is supported by the network interface card which is generally a ethernet card and motherboard. If the NIC and motherboard is manufactured in the past decade or so they will support the Wake On LAN features. The Wake On LAN is configured through the BIOS menu or the NIC firmware configuration.

网络接口卡(通常是以太网卡和主板)支持Wake On LAN功能。 如果NIC和主板是在过去十年左右的时间内制造的，则它们将支持Wake On LAN功能。 可通过BIOS菜单或NIC固件配置来配置Wake On LAN。
