Algorithm Implementation almost all presentations in the other tracks contained
ideas on algorithms and their implementation
this track focused on novel ideas tendency to implement more complex algorithms in FPGAs

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
