AS/400 IBM Network Station: Techniques for Deployment in a WAN
section. The following Network Station functions are included in the
discussion:
• Time to initialize the Network Station (prior to login) for Ethernet,
Token-Ring and twinax
• Time to load the applications (5250 emulation, browser, and so on)
• 5250 application performance
• Browser performance
• Java Virtual Machine (JVM) applet or application performance
• Times for the Network Station Series 100, 300 and 1000
The computer industry has a generic name for the IBM Network Station - the
thin client . Because clients attach to servers, it may seem that an AS/400
server model attached to a Network Station (a thin client) would always be the
best fit (that is, client-to-server). Be cautious when the Network Station is
attached to an AS/400 server model as contrasted to a traditional system
model. When using 5250 applications, the Network Station looks like a
non-programmable terminal (NPT) (such as an interactive job) to the server
and is subject to the AS/400 server interactive rules. Therefore, it may not
always be a good choice. The traditional AS/400 system models with the
Network Station are always a good choice.

Table 2 on page 39 shows the amount of data that flows from the AS/400
system to each Network Station for initialization and each application load.
