Discuss

• Reliable Link is not guarantee in TCP/IP for a
  long time because of noise
• .increate main nodes for data exchange
• .UDP link for monitor system
• Local DataBase establish for physics beam tune
  and them interface
• .use commerce DB
• .server/client Architecture

Conclusion

• Control system is flexible and open.
• System diagnosis perfect include.
• Only 23 person to do all hardware and software.
• Graphics class is developing because of less
  human resource.
• EPICS will start basing on the fieldbus lay.
