Fast Networks and Event Building

use of fast networks in readout-systems and event building solves many problems of the past

most implementations shift from custom solutions or ATM to Gbit-Ethernet

Online Processing Farms and High Level Triggers in the last generation of experiments, computing

farms were only used offline

most experiments run higher level trigger algorithms on computing farms as part of the online system

some experiments investigate the possibility of using remote computing farms in real-time for trigger and data acquisition

online computing farms are a challenge for infrastructure in terms of cooling and cabling

Conclusions and Outlook two main directions in 2005

placing more complex algorithms into hardware FPGA

change of mind less sophisticated real-time trigger complete read-out at higher rates

Real Time 20xx combine the trends?

complete read-out in hardware low-level trigger high-level trigger DAQ
