COMMUNICATIONS SERVER FOR LINUX FOR S/390 DEVELOPMENT

1. Subject

Communications server for LINUX for S/390 development

2. Purpose of this proposal

In order to bypass shortcommings of current TN3270 server solutions such as 2216,OS390

TCPIP+OSA

Current solutions shortcomings

3. In order bypass above shorcommings following connection and configuration is proposed

Configuration

Shortcomings

CISCO or 2216Os/390

Need external devicerouter

Need external deviceRs/6000Os/390

3270 LU definition is Incompatible with

Client

IEEE802.2 TCU EMULATION Note: 1. Remote 3270 client wants to logon SNA host lpar 1 ,and issue logon command 2. Through tcpip lan network the logon message arrives lpar2 linux TN3270 server

3. This linux TN3270 server converts tcpip node as SNA LU

4. This SNA lu is connected to simulated PU within linux TN3270 server

5. Through OSA CARD PAIR AND IEEE802.2 protocol that lu can access host application

4. Benefits

-NETVIEW can manage TN3270 network

- No need external device such as 2216

- PU,LU node definition coding is VTAM compatible

5. The items to be developed

- Above lpar2 linux base TN 3270 SERVER(can convert from RS6000 AIX base comm.server s/w) is not ready made so needs further developement

- Lpar1 VTAM AND OSA s/w is already made ,so no need development
