Example Configurations

SNAplus2 can be used as a standalone system to support direct communication with a host or another SNA node, within a LAN to support SNA communications across the LAN, or as a gateway to support communication between a host and systems in a LAN.

A computer running SNAplus2 configured as a standalone system that communicates directly with a host computer is shown in Figure 2-1 “Standalone SNAplus2 Node That Communicates Directly with a Host”

Several SNAplus2 nodes configured as an APPN network are shown in Figure 2-2 “SNAplus2 Nodes in an APPN Network” SNA is used for peer communication within the LAN as well as over the SDLC link.

In Figure 2-3 “SNAplus2 Node Providing PU Concentration and DLUR” a computer running SNAplus2 provides TN server support for TN3270 and TN3270E clients. The TN server node and the clients communicate through the TCP/IP network.

In Figure 2-4 “SNAplus2 Node Configured for TN Server” a computer running SNAplus2 provides TN server support for TN3270 and TN3270E clients. The TN server node and the clients communicate through the TCP/IP network.

A network that includes SNA nodes (SNAplus2 servers) and non-SNA computers (SNAplus2 clients) is shown in Figure 2-5 “SNAplus2 Client/Server Configuration” The clients can access SNA resources through the servers.

These examples show the most basic ways in which you can configure SNAplus2 nodes. By combining nodes using these basic configuration types, you can use SNAplus2 to support different types of communication within more complex networks.
