G&R
The G&R/Ggate product off-loads the DSA session protocol into gateways.
By running Ggate on the system(s) with the mainframe connections the
emulator platforms need only the very small and efficient Ggate protocol layer
to connect over TCP/IP to a Ggate gateway with full native Bull network
functionality. Ggate can make the mainframe connection using OSI-transport or
RFC1006. If you must use OSI-transport for the mainframe connection, using
Ggate will limit the need for OSI-stacks to the Ggate platforms.
The Host Links Installation and Configuration manuals cover the OSI stack
installation and setup for the supported UNIX and Windows server systems.
Bull systems can also be accessed using Telnet VIP (TNVIP). The TNVIP
servers in the MainWay, the Bull DPX/20, GCOS8 GNSP, the Open Systems
personalities of GCOS7 Diane systems and G&R/Ggate are all qualified.
However, RFC1006 will increase throughput as compared to using TNVIP. It
will also give a real, fully functional DSA or DIWS session over the TCP/IP
network, as compared to the limited terminal session offered by TNVIP.
IBM systems can be accessed using DSA into the Bull front-end and the
OSF/SNA gateway (supported in the Datanet and MainWay). IBM systems can
also be accessed using Telnet 3270 (TN3270 or TN3270E) to connect to any
TN3270ÙSNA gateway or front-end. The MainWay gateway, the TN3270
server on the Bull DPX/20 UNIX systems, the IBM TN3270 front-end and the
TN3270 server for Windows are all qualified. Additionally, IBM AS400
systems, or other host systems that supports the 5250 family of terminals, can
be accessed using Telnet 5250 (TN5250) connecting through a Telnet 5250
server.
