PPT Slide
Purpose
- eGentGridAgent proxy is used to connect (wireless) eGents in the field to grid-accessible agents on a LAN
Demo scenario
- PSMs on troops updated with latest status information (geographic, health, threat, …)
- other parties (PSM clients like command post or medevac) subscribe and receive inform messages in response to changes
Displays
- PSM Server is displayed in one Java window
- DOS windows show activity of the eGentGridAgent proxy and Grid's log agent
- PSM Grid Client is displayed in another Java window
- Netscape Messenger shows the log of eGent messages
-
Demo step-through shows
- registering the PSM Server eGent with the eGentGridAgent proxy which then registers it with the Grid
- switching to the PSM Client agent, which subscribes to the PSM Server by sending a lookup message to the Grid Registry, which finds the proxy, which the client thinks is the PSM Server, and then sends a subscribe grid message to the proxy, which passes it along to the PSM Server
- then PSM Server sends back an inform message containing the subscribed values (and sends updates later if any values change)
- the messages thread their way back through the system to eventually be displayed on the client.
- If you modify a value on the server, you can watch the update propagated back to the client
- You can view the eGent message log with Netscape Messenger.
