Controlling the amount of network bandwidth used
Symantec Ghost lets you control how much network bandwidth is used when
GhostCasting. By using this functionality, you can avoid overloading the network
with GhostCasting traffic.
You can enter a value for restoring an image, creating an image, or both. The
values are saved and loaded the next time that you run the GhostCast Server.
However, if you run a GhostCast session from the command line, the limits that
are set on the command line are used for that session only.
See
"GhostCast Server command-line options"
Limiting network bandwidth is useful in some circumstances. Consider the
following:
By limiting network bandwidth, you can increase performance on the network
for users who are not the intended recipients of image files.
If your network hardware does not support multicasting, then limiting
bandwidth is helpful in many situations.
Table 8-2
provides a guide to network hardware setups and when you may or may
not want to limit network bandwidth.

Subnet targeted broadcast

In situations where you would not limit network bandwidth, the hardware directs
the traffic to intended recipients only, and all other users should be unaffected.
To set a limit for network bandwidth
1
In the Symantec GhostCast Server window, on the File menu, click Options.
2
In the Options dialog box, check Limit data throughput for.
If this option is not enabled, then no limit is set.
