• About This Issue
• 3745/3746 Year 2000 Readiness

All models of the 3745, and 3746 Models 900 and 950, are Year 2000 ready with an appropriate microcode engineering change (EC).
• Network Utility Provides IP-SNA Integration and High Session-Processing Capacity

Providing simple, scalable TN3270E capacity and high session-processing capacity for memory-intensive tasks, IBM's new Network Utility offers IP-SNA integration and high-capacity transport solutions for the 3745/46 owner.
• Networking Implications of S/390 Parallel Sysplex

The S/390 Parallel Sysplex configuration provides many benefits to the large mainframe environment, including high availability, workload balancing, scalable growth, reduced cost of computing and investment protection of current applications. This article discusses the networking implications of Parallel Sysplex, especially focusing on applications where high availability and workload balancing are required.
• Frame Relay/ATM Interworking with IBM's 8265 Nways ATM Switch

Two of the switched networking technologies that many large enterprises are deploying in their businesses today are coming together to offer users exciting new alternatives for designing their enterprise networks.
• Connectionless Network Prioritization: Is it Real?

An IP network does not guarantee a fixed path for traffic flows. Also, the status of resources in the "IP cloud" supporting any data flow between TCP endpoints is unknown. Both statements are also true about IP Next Generation (IPng or IPv6) environments. The net result is that every IP data packet is transported as a self-contained message.
• 3174: "Not Just A Display Cluster Controller"

The paradigm shift from legacy S/370 and S/390 host-centered hierarchical networks to distributed client/server-based solutions has left many IS managers looking for ways to leverage costly investments made in their traditional network infrastructures. In this context, the IBM 3174 Network Controller has proven itself to be a performer well beyond its originally intended position, that of a display cluster controller.
• Focus on 3172 ICP Diagnostics

This article guides you through the basic ways to perform ICP software diagnostics the 3172 Nways Interconnect Controller.
• Addressing a New Networking Paradigm -- High-Speed Connection Networks and Quality of Service

A new paradigm is emerging: links are expected to be faster than nodes in a high-speed networking world. Experience and research support the simple fact that connections will be required for performance and stability in this new paradigm.
• NCP and 3745/46 Capacity Planning Case Studies

CF3745 is the hardware configuration tool for the 3745 and 3746. It resides on HONE and is available directly to customers through IBMLink. CF3745 also contains performance and storage models that are used for capacity planning.
• Network Traffic Analysis (NTA), a Service Offering Since 1989

For many years, NTA has been solving SNA subarea performance problems with a finite state machine (FSM) approach by electronically analyzing network traces.
• What's New with ACF/NCP
• Library Update
• Connection Balancing for 3745 Frame Relay BAN

In recent years, Frame Relay networks have established themselves as efficient and reliable alternatives for transporting mission-critical data. As a result, new methods for carrying Frame Relay traffic have been developed.
• 3745 NCP and 3746 Model 900 Supports Switched Frame Relay

With NCP V7R6, IBM introduced switched Frame Relay physical ports on the 3745 for SNA peripheral traffic (routed and bridged) and SNA subarea traffic. NCP V7R7 has extended this support to the 3746 Model 900 and added IP support for the 3745 Switched Frame Relay.
• New CIR Support for NCP-Controlled 3746 Model 900 Frame Relay Lines

NCP-controlled 3746 Model 900 Frame Relay lines can now take advantage of Committed Information Rate (CIR) algorithms available for Network Node Processor (NNP)-controlled Frame Relay lines.
• NDF Changes Engines

After 15 years, NCP/EP Definition Facility (NDF) is bidding a fond farewell to the IFZ assembler (VSE) and the IHR90 assembler (MVS and VM), beginning with SSP V4R7. NDF will instead be invoking the IBM High Level Assembler, which is available for all operation systems.
• Emulation Program R14 Now Supports All 3745 Models

The latest release of Emulation Program, Release 14 (EP R14), has been packaged so that the single tape supplied can be used for both Partitioned Emulation Program (PEP) and EP standalone installation.
• Continued Investment in NTune Family Provides Exciting New Capabilities

Continuing our commitment to offer the best possible network management capabilities to our 37xx users, we have made significant enhancements to the NTuneMON and NTuneNCP application family.
• 3745 and 3746 Model 900 IP Routing

Although the 3745 and NCP are not intended to be a high volume IP router, the ability to route small amounts of IP traffic over varied interface types is an important connectivity option.
• NCP Service Dates
• Strategic Development of SNA Networks

SNA network administrators are faced with two fundamental requirements: TCP/IP openness and the development of infrastructures. This article outlines the kind of strategic development IBM is looking for and demonstrates how IBM can tailor that development most appropriately to the progress of each company.
• Did You Know?
• Do You Use a 3705, 3720, or 3725?

On January 20, 1998 IBM announced the withdrawal of maintenance service on the 3705, 3720, and 3725 in North America. The effective date of maintenance withdrawal is January 1999, allowing customers time to consider migration plans on these communication controllers.
