SNA Migration Example

The Gateway will route the data based on the incoming address. In this example, the Gateway 530 emulates a terminal to the IBM system, a host to the bisync and SNA/SDLC devices and a client to the local Server. Data from the bisync system is converted to TCP/IP and transmitted to the Server. Data from the 3270 terminal is sent to the IBM host.

The Gateway converts the addresses for all of the devices at the remote location. The Gateway maps the addresses so the host only has to poll one PU at a location. This capability can reduce host overhead and minimize network changes.

In this example, the Gateway routes the data at a local level between the various devices and then finally converts it to a terminal emulation for transmission to the remote host. As the Server applications are completed, the 3270 controller and bisync devices will be eliminated. The G530 will then continue to perform an IP to SNA conversion.
