Real time. 4 meetings so far. Consensus: Real-time will be required to operate the LHC. The demands on speed appear to be reasonable, and data acquisition, or measure & correct appear to be necessary at a maximum of 10 Hz. Bandwidth requirements are also moderate.

Response limited by PC/magnet
Which should allow 10 Hz
Characteristic frequency is low
Real-time LHC controls network
RT LHC Network
Up to 30 Digital Controllers Per WorldFIP fieldbus
~1700 Digital Controllers
Beam Instrumentation and Power Converter systems are
planning on providing
real-time acquisition and correction from the front-ends
to at least the gateway level.
Ethernet by appears to be capable of providing
the necessary level of performance via dedicated Gigabit Ethernet
A real-time environment will be necessary at the high-level.
A logical architecture is required to allow the implementation
of a well-designed, integrated system
A generic approach will be adopted to provide standard facilities.
