Table A3-1 Packet Data
Data Description
xxxxxxxxxxxxh Destination Address consists of 6 byte.
This Address is specified as Fixed Address or Broadcast Address.
If the fixed Address is specified, Wakeup Frame is enabled for the client with
that address.
However, the Client is in Power Off mode, Data Transfer is not performed and it
can be deleted on other Node by the Routing Table or Internal Cache
depends on the Protocol.
Also, the destination of the address is unkown for the Router and Node.
Therefore, the Wakeup Address directly addressed to the terget client is
deleted.
This problems can be solved using the Broadcast Address.
In the Directivity Multiaddress Calling, Router and Node forward the address to
the appropriate Network since it carries Network Address and Multiaddress
Calling Host Address.
Therefore, it can detect the Directivity Multiaddress Calling as MAC Level
Multiaddress Calling even if the client is on the Power Off mode.
