Content

Communications Server for Windows v6.4 replaces Communications Server for Windows v6.1.3. Version 6.4 delivers these additions:

  • Virtualization support for HPR connections such as Enterprise Extender
  • APPN enhancements for Path Switch delay support
  • IPv6 support for TN3270 Server, SNA API on Windows servers

Virtualization support for HPR connections:
Distributed Communications Server family of products provide improvements to HPR connections, especially Enterprise Extender (HPR/IP), when running in a virtual operating system environment. When a Communications Server is running in a virtual system like VMWare, XEN, Microsoft Virtual Server, there may be times when the real-time clock is not as accurate as needed. The new improvement uses Progressive ARB to handle directly attached links, including Connections Network links, to rely on buffer resources and not the real-time clock. This will provide more reliable connectivity and improved performance between a virtual system and a partner SNA node when the system is put under a heavy load.

APPN enhancement for Path Switch delay support
The Distributed Communications Server family of products now provides a setting for the minimum delay period, in seconds, before an HPR link will perform a path switch. When an HPR connection is determined to need a new route calculation, a minimum delay can be set so that excessive Path Switch occurrences are prevented. This helps keep the level of network traffic to a minimum as trouble spots in the network are found and corrected.

IPv6 support for TN3270 Server, SNA API on Windows servers
With this release, the Communications Server for Windows adds support for IPv6 clients for the TN3270 Server and SNA API server.
