Virtel can be configured to support a wide variety of web-enablement solutions, all based on the same host-centric thin-client architecture, which eliminates the need for client software additions (API), middleware, and intermediate servers:
- Web Access: replace 3270 emulation (TN3270) with pure web (straight TCP/IP) access without changing the (green screen) user interface.
- Web Modernization: serve host applications as rich web pages (GUIs) that combine existing 3270 data streams with JavaScript widgets and new AJAX-based application features.
- Web Integration: integrate host and server applications through interactive bidirectional connections such as XML/HTML web services.
Architecture of Virtel web-enablement solutions
All
Pure Web Access - Solution architecture
In its default configuration, Virtel replaces 3270 emulation (TN3270) with pure web (straight TCP/IP) access without changing the user interface: it serves the 3270 applications as web pages that retain typical "green screen" presentation and ergonomics.
The solution is based on Virtel's all-Assembler runtime, and the architecture is:
- Host-centric: runs on host as a started task in a partition under VSE or z/OS
- Two-tier: does not use intermediate server or middleware
- Thin-client: doesn't use any client software
Web page user interface (GUI) - Solution architecture
With custom configuration Virtel serves the host applications throught its integrated HTTP/S server as rich web pages (GUIs) that combine existing 3270 data streams with JavaScript widgets and new AJAX-based application features.
The solution is based on Virtel's all-Assembler runtime, and the architecture is:
- Host-centric: runs on host as a started task in a partition under VSE or z/OS
- Two-tier: does not use intermediate server or middleware
- Thin-client: doesn't use any client software
Emails & instant messages user interface - Solution architecture
With custom configuration Virtel serves the host applications throught its integrated SMTP server as emails and instant messages to mobile devices.
The solution is based on Virtel's all-Assembler runtime, and the architecture is:
- Host-centric: runs on host as a started task in a partition under VSE or z/OS
- Two-tier: does not use intermediate server or middleware
- Thin-client: doesn't use any client software
Web integration - Solution architecture
With custom configuration, Virtel integrates host and server applications through interactive bidirectional connections such as XML/HTML web services to expose 3270 transactions to server-based applications (e.g. WebSphere applications running on WAS) throught its integrated HTTP/S or custom IP server.
The solution is based on Virtel's all-Assembler runtime, and the architecture is:
- Host-centric: runs on host as a started task in a partition under VSE or z/OS
- Two-tier: does not use intermediate server or middleware
- Thin-client: doesn't use any client software
