	~~worst case~~ event~~/data rate predictions based on upcoming~~ experiments; ~~short term and long term~~, ~~in line~~ with ~~high-lumi task force~~		Valery presented event rates for electron and muon triggers for different experiments, results summarized in []; in general, for double luminosity we can expect reasonable rates below 50kHz; on next meeting Valery will present situation with mesonX triggers which is expected to be higher and less predictable then electron and muon triggers.

	* Ben/Sergey: VTP-based streaming front-end (mostly remaining issues); include in report ~~as ready-to-go short~~ term ~~solution;~~ long term ~~may require no~~-~~VXS anyway; 100k limit; new design compatible with streaming even if for 100k~~		Our suggestions in the final report will be based on the worst case event/data rate predictions. Short term and long term plans will be presented, in line with high-lumi task force.

	have ~~complete streaming front-end~~ to ~~let back-end and data processing development~~		Preliminary, following improvements will be needed in FPGA-based L1 trigger: (1) need more clusters in EC for muon trigger (not only max energy electron but also low energy MIP-like for muon); (2) q**2 cut improvement needs better dc roads resolution; (3) need more then one particle in one sector, may do it by counting of the number of the PCALU hits coincided with DC roads; (4) daq reliability issues appeared above 30kHz event rate have to be resolved.

	* Gagik/Nathan: realtime data processing in current daq L3, and in streaming daq (existing offline algorithms, new IA approach etc)		* Ben/Sergey: VTP-based streaming front-end in final stage of development, fixing remaining issues, Ben will work this and next week to resolve TCP problem in VTP; VTP-based solution will be included into final report as ready-to-go short term solution; long term may require no-VXS anyway; we keep in mind 100k event rate limit for L1-based daq; new design electronics have to be compatible with streaming day even if built to be used with L1-based system

			In close future, we want to have complete FADC250/VTP-based streaming front-end to let back-end and data processing development. As back-end progresses, we will add another electronics into streaming setups (DCRB, VSCM, etc).

			* Gagik/Nathan: realtime data processing in current daq L3, and in streaming daq (existing offline algorithms, new IA approach etc) - next time

	~~plan how~~ to modify L1 algorithms for not-FPGA processing, ~~try to implement DC by report time~~		Sergey was planing to modify L1 algorithms for not-FPGA processing, but maybe existing L1 improvements (as it discussed above) will be more needed, it will be discussed.

	* Rafo assignments

	~~???~~		* Rafo assignments - was not discussed today
