With SNA Server, a TP such as a 5250 terminal emulator might use an APPC LU alias to communicate with another TP. In this case, the LU alias maps to an LU name that is actually used to communicate with the TP on the other system.
When a client/server network TP requests a conversation with a TP on the AS/400 (the remote system), SNA Server (the local system) acts on behalf of the client request and negotiates an LU 6.2 to LU 6.2 session to the AS/400. The data sent or received from the AS/400 TP is handled by the server and sent to the client TP over the selected client/server protocol. Figure 10.13 shows an APPC conversation using SNA Server.
Figure 10.13 APPC Conversation Using SNA Server
Note
In Figure 10.13, the perception of local and remote LUs depends on the system you are configuring. When configuring SNA Server, the local APPC LU corresponds to SNA Server and the remote LU corresponds to the AS/400. If you view the configuration from the AS/400 perspective, the AS/400 is the local APPC LU and SNA Server is the remote LU.
