The QuikConnect philosophy
Applications should operate seamlessly over
the Internet, regardless of the individual
platform or physical location -- just as
applications run today on host
computer operating systems.

QuikConnect user profile
SEC EDGAR Project
TRW, on contract to the US Securities Exchange
Commission, used QuikConnect as the message-oriented
middleware for a large multi-host, mixed-vendor system.
QC is the “glue” that interconnects HP-UX, Solaris,
Stratus VOS, Stratus FTX, OS/2, and NT machines for
the Electronic Data Gathering and Retrieval System
(EDGAR) to report all corporate filings to the US
government. It can be viewed at www.sec.gov

QuikConnect benefits
Combines
• Fault tolerant processing power of the Stratus server
• User interface features of desktop workstation
• Speed and reliability of a LAN
• Open Systems architecture
Provides
• High performance access to distributed applications
• Distributed client application processing
• No required changes to existing server applications
• Access to “off the shelf" tools and applications

QC Distributed Client Benefits
 Takes advantage of PC tools like Windows, graphics, imaging
 Allows application processing without using critical server
computing resources
 Applications include image capture, data entry, editing, local
file access, terminal management
 Improves transaction throughput:
• Data transferred at LAN speeds
• Processing matched to architecture of computer
• Breaks application at most efficient point
 Retains fault tolerant server essential to application
 Provides flexible system expansion

QuikConnect offers Stratus users:
VOS to Unix (HP-UX, Solaris, FTX) application migration
 Servers or requesters can be ported separately
 VOS & Unix requesters can access same VOS servers
 VOS & Unix requesters can access same Unix servers
 VOS requesters can access both VOS & Unix servers
 Unix requesters can access both VOS & Unix servers
VOS to Unix ports
 VOS applications can retain VOS-like TPF
architecture when ported to HP-UX, Solaris or FTX
 VOS users can continue to use familiar TPF facilities
