TCP/IP Version 2.0 for MS-DOS

TCP/IP Version 2.0 for MS-DOS is the latest program in the TCP/IP family, and it replaces TCP for the PS/2. TCP/IP Version 2.0 for MS-DOS provides a set of TCP/IP protocols to enable users to perform file transfer, remote execution, remote data access, remote printing, remote logon, and TCP/IP application development. TCP/IP for MS-DOS interoperates with other vendors’ TCP/IP products that provide equivalent protocol support. TCP/IP Version 2.0 for MS-DOS, TCP/IP Version 2.0 for MS-DOS Programmer’s Tool Kit and TCP/IP Version 2.0 for MS-DOS Network File System Kit will be available October 25 in the US.

ACF/NCP Version 6 Expanded Networking Capabilities

Advanced Communications Function/Network Control Program, ACF/NCP, Version 6 supports the new adaptor for the 3745 communications processor, which provides communications for Ethernet Version 2 or IEE 802.3 local area networks. By using Internet Protocol, ACF/NCP Version 6 provides for the routing of traffic across an SNA network from a workstation on a network to a workstation on another, or to a host-based TCP/IP application. Also, ACF/NCP Version 6 provides for the attachment of the 3745 as an Intermediate Network Node to a Frame Relay network. Other highlights include the capability for network charges to be based on the specific session transmission priority and for specific alert notification when held or congested virtual route conditions are determined. Version 6 enhancements will be available on September 25 1992.

ACF/SSP Version 3 Release 7

The Advanced Communications Facility/System Support Program Version 3.7 provides generation and utility functions for ACF/Network Control Program Version 6 and Emulation Program Release 10 that are equivalent to those provided in ACF/SSP Version 3 Release 6. ACF/SSP Version 3 Release 7 is said to provide additional functional capabilities in the MVS/370, MVS/XA, MVS/ESA, VM/SP, VM/XA, and VM/ESA environments; v3.7 arrived for MVS and VM September 27.

The X25 Network Control Program Packet Switching Interface, NPSI, Version 3 Release 5 is said to offer performance and systems management enhancements over previous releases of X25 NPSI, as well as currency with Advanced Communications Function for Network Control Program Version 6. X25 NPSI Version 3 Release 5 supports attachment of the 3745 Communication Controller to data transmission services that comply with CCITT Recommendation X25 at speeds of up to 2m bits per second. User productivity is also improved in the General Access to X25 Transport Extension environment by the Fast Transaction Processing Interface which raises throughput by blocking multiple X25 packets into single SNA Path Information Units, and restart is claimed to be improved by reducing the number of pre-established logical unit-to-logical unit sessions required. There is a new timer to protect against loss of responses in the X25 network, and systems management is improved by Calling Data Terminal Equipment address verification. The new interface will be out for MVS and VM by September 25, 1992.

SystemView Network Management Strategy

IBM has announced the SystemView Network Management Strategy which outlines its evolving system and network environment. Systems integration, open access, and network management are said to be key elements. It is intended to provide a clear direction to enable information system growth, provides the framework for customer management implementation, positions IBM’s offerings with industry standards, manages different network environments, provide complete, ready-to-go network management solutions and improve overall availability of network services to users, IBM says.

NetView Version 2 Release 2 Enhancements

NetView Version 2 Release 2 enhancements include two transport implementations of LU 6.2 support and capabilities that will enable users to send to distributed hosts, and receive responses. Also, NetView enables operators to access a central Information/Management database or other database via the Ne

tView Bridge from remote MVS, VM, and VSE systems. Its remote automated operations capabilities are claimed to be enhanced through implementing the SNA operations management architecture and SNA focal point architecture. NetView will receive and automate alerts without translating into messages and it provides for direct automation of other architected data. The Installation Facility supports installation of the NetView Graphic Monitor Facility on MVS/XA and MVS/ESA, and the NetView-to-NetView transfer limit has increased to 32Kb from 255 bytes. NetView Version 2 Release 2 under MVS/ESA and MVS/XA will be available September 30, the VSE version ships December 31 and VM/ESA is available March 31, 1992.

NetView Version 2 Planned Enhancements

In a promises, promises announcement, IBM says it intends to provide functional enhancements in NetView Version 2 Release 3 for MVS/XA and MVS/ESA in the areas of graphics and automation. These will be provided by extensions to the NetView Graphic Monitor Facility and the introduction of the Resource Object Data Manager, an object-oriented programming environment for systems and network management. Enhancements to the Monitor Facility will include support for heterogeneous networks; an integrated command facility; an expanded set of views; and interfaces to Information Management for performing problem management procedures and accessing component data. These enhancements incorporate functions available through NetCenter, and the use of GraphicsView/2 provides consistent interfaces that are compliant with Common User Access and SystemView end-use dimension definitions level 1. The Resource Object Data Manager is to provide services for systems and network management. It supports an in-memory data store that permits operational information relating to resource objects to be consolidated in a single source. Applications can share the facility’s resource control information data and use its services and application programming interfaces to develop expanded system management support. There is to be a field test for selected customers that will start in the first quarter of 1992, and IBM says that it is planning to announce general availability in May.
