31 虚拟架构访问的工作流程 3. Web server forwards 8. Portal server creates unique ID 5. Client presents credentials address to portal server (JNLP) for connection, Then tells back to portal server 7. If authenticated, portal queries tunnel server to expect connection tunnel for connection 6. Portal based authenticates on user 10. Initiation of tunnel load balancing against a Directory service sequence begins secure 4. Portal socket server layer (SSL) sends login page to client Ready for ID ID Created (JNLP) Java network launch protocol Tunnel Portal Existing Systems Access Device ( Java enabled) 1. User enters VIA url Web 9. Portal returns Web page to client browser. 11. SSL Tunnel is created once the ticket is authenticated. Directory Messaging Terminal Existing Data 2. DNS server resolves I/P then forwards request to the Web server. Database File Services 12. Access to Application is granted and launches.
