AS/400 IBM Network Station: Techniques for Deployment in a WAN
4.5 Roaming Feature
The roaming feature allows mobile users (for example, users that are not at
their home systems) to use the facilities of a remote system to access their
local user-based terminal setup.
At the Network Station login dialog screen or display there is a
Roam button
that allows you to locate your home configuration files. The user that is
visiting New York can still authenticate and get his desktop settings from his
home server in Chicago and boot from the local system, therefore, saving
management overhead, bandwidth utilization, and time.
Figure 31. Roaming Example
In Figure 31, a user from Chicago is visiting the New York site. There are
servers in both Chicago and New York.
The server in New York provides the following to the Network Station:
• The IBM NetworkStation’s IP address
• The operating system and applications
• The terminal-based configuration information
• A login dialog or display
