2. Wake on LAN Technology
The adapter is an ACPI-compliant network adapter that supports the following features:
_Power management interface
_Remote wake-up (RWU)
ACPI (Advanced Configuration and Power Management Interface) ACPI is a key element in Operating System Directed Power Man- agement. It is a specification developed by Intel, Microsoft, and Toshiba Corp which allows more advanced power management fea- tures through the operating system to the hardware interfaces.
Remote Wake-up (RWU)
The Remote Wake-up feature is provided by Wake on LAN (WOL) technology that resides in a network adapter and on the system motherboard in a LAN environment. When a system is in a standby or suspend state, the network adapter continuously monitors the network and watches for a wake-up packet. When it receives that packets, it alerts the system, which then comes to a full power state and stands ready for maintenance or other tasks.
Wake-up Packets
The adapter supports the following wake-up packet types:
_Magic packet wake-up
_Microsoft wake-up frame
The wake-up packet is a valid Ethernet packet that contains a syn- chronize data stream and the destination MAC address. It is not protocol specific and can be routed in order to wake up a remote PC.
