Title
Middleware
Names
- session leader
- participants
Technology/Function description
Goal
- Slicer + IGSTK
Technologies
- Publish subscribe ORB/ACE [Peter]
- Socket IGSTK [Junichi Patrick]
Requirements
- Reliable for command transfer (all data transferred, in order)
- Fast for tracking data transfer (only the latest coordinate is required, can lose data)
- Image transfer (500K or more)
- Data types (struct: string, integer, float)
- Data type checking (number is correctly formatted etc)
- Time out (device is down)
Would be nice to have
- Priority
- Point - multi-point data transfer
Questions
- UDP - fast, no delay due to ACK packages
- TCP/IP - reliable, easy
- Security
- malicious packets or sent by mistake
- CRC and auth.?
- pop up a dialog box before accepting data? (just one, to avoid flood)
- same issues with Slicer3:Slicer_Daemon
