< About the Magic Packet™ frame >
In a Magic Packet™ frame, the SOURCE ADDRESS, DESTINATION ADDRESS (the
MAC address of the receiver or the MULTICAST ADDRESS including the BROADCAST
ADDRESS), CRC, and the like must meet the basic requirements of the LAN in use. The data
in a Magic Packet™ frame consists of a sequence of 16 repetitions of the MAC address of the
node. This sequence can be anywhere in the packet but it must follow a synchronization stream.
The synchronization stream is defined as 6 bytes of 0xFF. As long as the MAC address that
repeats itself 16 times targets the address of the equipment to be started, the device can receive a
BROADCAST frame.
A Magic Packet™ frame is shown in the following figure.
