  2. Coming up: • What is ComNet? • How does it work? • Features • What can it do? • Comparison to other approaches • Summary

  3. What is ComNet? • Communications protocol converter • Provides a session between two distinct connections • A connection can be a comm’s line or an Application • ComNet handles the protocol conversion so thateach connection believes that the other is using the same protocol • Software solution • Runs on NonStop Guardian

  4. ComNet fits into your environment: …between a DEVICE and an APPLICATION…

  5. ComNet fits into your environment: …between a DEVICE and another DEVICE…

  6. ComNet fits into your environment: …and between an APPLICATION and another APPLICATION.

  7. Converts any-to-any protocol: • Async • Bisync • Interprocess • SNA • SNA LU6.2 • TCP/IP • X.25 • More coming…

  8. Feature - Backup connections ComNet can provide multiple backup connections on each side of a Session.

  9. Feature - Backup connections ComNet can provide multiple backup connections on each side of a Session.

  10. Feature - Backup connections ComNet can provide multiple backup connections on each side of a Session. • Rotary of alternateconnections • Customizableretries, intervals,cycles • Alternate rotary tocater for site failures

  11. Feature - User library ComNet has a User Library which can be substituted with your own. • User library has access to messages passing through ComNet • Ability to perform message format conversion

  12. Feature - Scalable • Thousands of Sessions per ComNet process • Logically unlimited number of processes across multiple processors • Presented as single system image in operator interface • Wildcards • Filtering on Protocol, Session State, Backup Connection..

  13. Feature – Ease of use • Easy to install • Copy 5 object files & run license setup • Easy to configure • Simple configuration structure • Defaults to existing line configurations • Easy to operate • Automatic recovery • Familiar STATUS, START, ABORT commands • Easy to maintain • Replace a file if required.

  14. Application - Protocol substitution ComNet can provide additional protocol support, or replace existing protocols or protocol handlers. • Add protocol support • Instantly TCP/IP-enable your Application • No changes to your Application • Phased migration • Replace expensive protocol handlers

  15. Application - Communications server Any Application can use ComNet as its communications handler simply by opening ComNet and using only basic Guardian calls such as WRITE and READ. Never develop a communications handler again. • Simple WRITEand READ calls • All protocols available • Automatic backup connections • Operations infrastructure • Save time, cost, maintenanceand QA

  16. Applications - Testing support ComNet can provide a TCP/IP connection between your legacy NonStop Application and your LAN, which means that you can now use GUI feature-rich PC test tools to test your Application. • Removes legacy bandwidth limitations • No legacy comm’s ports required • Unlimited number of simulated legacy ports

  17. Application - Loopback connections ComNet can provide a communications loopback connection directly between two Applications without any hardware. • No hardware required • No Access Method involved • With or without protocol conversion

  18. Another approach - Encapsulation • Also referred to as “tunneling” • Not a conversion. It’s one protocol over the top of another protocol • Eg. DLSw (SNA over IP), XOT (X.25 over IP) • Allows network backbone replacement (with IP) • Polling of legacy protocol may still be carried across new network (can be ~30% of network traffic) • Potential flow control issues (eg. different protocol timing and network latency issues – may cause timeouts, retransmissions) • Spending on additional hardware and software to preserve legacy environment when could be investing in new technology • Maintenance of legacy hardware continues.

  19. Comparison – Conversion vs Encapsulation

  20. Another approach - Hardware • External device • Computer room space, power, cabling • Operations • Maintenance of legacy hardware continues • Future support of hardware may be more difficult

  21. Comparison – Software vs Hardware Protocol conversion

  22. ComNet Features Summary • Any-to-any protocol conversion • Multiple backup connections per session • Dynamic configuration • Loopback capabilities • Customizable with your own User Library • Powerful operator interface provides seamless global view and control over all ComNet sessions • Scalable architecture to support thousands of sessions • Quick and easy to install and maintain.

  23. ComNet Benefits Summary • Low cost • Reduce legacy comm’s hardware • Eliminate some SWANs • Avoids the expense of new protocol conversion hardware and its deployment, maintenance and operational costs. • A software solution which is easy to install, maintain and operate • Flexible short term and long term licensing options • Reliable • Multiple backup connections for every session • Utilizes highly reliable HP NonStop communications hardware • Flexible • Dynamic configuration • Scalable across multiple processors • Suitable for broad range of application.
