The intent of this newsletter is to publicize items of interest for both IBM and customer personnel who have an interest in TCP/IP. Articles from development, marketing, and users are all eligible for inclusion in future issues. If you have an item of interest that you would like to have published please contact Alan Reinhold (8-352-3173 or 919-301-3173).

TCP/IP for MVS - Version 2.2

A new release of TCP/IP for MVS has been announced. Two new features, CICS Socket Feature and Offload for OS/2 Feature, will also be available. New and enhanced features:

  • CICS Sockets for Client/Server applications
  • MVS Offload using new 3172 Model 3
  • Print support using LPR/LPD
  • REXEC Client / Kerberos / NCS
  • Network Database support (NDB)
  • FTP batch SQL Query support
  • SMF -TELNET/FTP Server Support
  • RISC/6000 Channel Attachment
  • Host Channel to Channel, CETI, and HIPPI

New Model of 3172 Interconnect Controller - Model 3

The new Model 3 LAN gateway supports sending information from Token-Ring, Ethernet, and FDDI Local Area Networks to mainframes.

With TCP/IP offload, some of the TCP/IP work is handled by a 3172-003 instead of a mainframe, thereby freeing the mainframe to handle other tasks. Freeing the resources of a mainframe, approximately 30% for many TCP/IP for MVS file transfers, can mean savings equal to a tenfold return on the investment in the new controller and TCP/IP Offload application.

The Model 3 when running with the new licensed program, Interconnect Controller Program (ICP) Version 3, performs twice as fast as the Model 1 due to a powerful Intel 80486 microprocessor. This improved performance is especially attractive to users who need to share large data files, such as those used in scientific and engineering applications, with other users on the network.

FTN TCP-V2.2, 3172, and Directions July 10

This one hour Field Television Network broadcast will review the recent announcements and present IBM's Trends and Directions for TCP/IP on the host and workstation platforms. Broadcast receive facilities are in all IBM branch office locations and are available for direct customer receipt with satellite receive capability. The broadcast will be at 9:30AM EDT and repeated at 12:30 EDT for West Coast reception.

New Network Queuing System/MVS (NQS/MVS) Program Product (Program Number: 5695-168)

IBM has announced the IBM Network Queueing System/MVS Version 1 Release 1. The Network Queueing System (NQS) protocol is a popular method for submitting batch requests to remote UNIX machines over a TCP/IP network. NQS/MVS expands this open systems solution to include the submission of batch requests to an MVS TCP/IP platform. NQS/MVS acts as a mediator between the NQS protocol and MVS JES2 services.

NQS/MVS extends the standard NQS commands for submitting, cancelling, and checking status of jobs on MVS directly from a UNIX workstation; the user doesn't have to log on to TSO. A user can request either that output be sent back to a workstation, or that it remain on MVS for later reference. This is particularly beneficial if workstation users already were using NQS. Rather than learning new commands and new programming languages, user can use virtually the same commands to do batch job processing on remote UNIX and MVS machines.
