Interoperability with IBM Host Systems

Windows 2000 Professional uses SNA Server Client to establish connectivity to an IBM host when an SNA Server is implemented as the gateway. Included with SNA Server Client are two host emulation applications, 3270 Applet and 5250 Applet. The 3270 Applet is used for communicating with an IBM mainframe. The 5250 Applet is used for communicating with an AS/400. The SNA Server components communicate through SNA Server Client, which communicates with SNA Server. SNA Server communicates with the IBM host, as illustrated in Figure 26.6.

Note

All host emulation applications that have access to an IBM host through SNA Server communicate through SNA Server Client.
