Transfer options
Use if Description Mode
You are transferring a data packet
to one or two computers only. Each packet is addressed to one
computer. One stream of data is sent
for each client. Unicast
Your network hardware does not
support Multicasting. Data is sent to all computers on a
specified subnet. If clients are on
more than one subnet, one stream
is sent to each subnet. Directed
broadcast
Unicast or subnet targeted
broadcasting are not appropriate. Data is sent to all computers on the
network that have requested the
data. Only one stream of data is sent. Multicast
Multicasting is usually the most efficient option for the following reasons:
■
Only one stream of data is sent out for all clients.
■
Multicasting sends packets only to client computers that have requested data
from the GhostCast Server.
This requires the support of appropriately configured routers and switches. You
can alter settings globally or for a GhostCast session.
Symantec Ghost attempts to use Multicasting by default. If you have set the data
transfer mode to Unicast or Directed broadcast, then Symantec Ghost uses that
method. If Directed broadcast or Multicasting fails, then Symantec Ghost attempts
to use Unicast.
To set the data transfer mode
1 In the Symantec GhostCast Server window, on the File menu, click Options.
2 Click Force Mode.
