- Near Term:
  - Hall-B FT calorimeter and hodoscope streaming readout test - Pending OK from Sergey B.
    - May be able to use Abbott's indra-s1 setup
    - May be to use new VTP f/w with Hall-B VTP's - (Ben Raydo)
    - CODA 3.10 + ERSAP for new VTP f/w
    - CODA 2.0 for old VTP f/w
  - HOSS Hall-D EJFAT use case
    - parallelize writing of raw data files
    - distribute raw data across multiple compute nodes for calibration skims
    - 1 Gbs at hi-luminosity
    - Control Plane
      - Feedback from Compute hosts
      - Control Plane daemon for compute host
      - Demonstrate CP based flexibility/elasticity
    - Hall-D comms with DAQ 109 subnet require network customization; DAQ 29 subnet available
    - Slides
    - Netwok Diagram

-**** Update firmware on all 3 VTPs to send fADC aggregated data frames in the EVIO format, through UDP.
+**** CODA 3.10 + ERSAP for new VTP f/w
-**** Design ERSAP FE application containing an actor that receives VTP frames through UDP, extracts information about the source/data ID and frame number (tick), and sends it to the EJFAT packetizing engine.
+**** CODA 2.0 for old VTP f/w
-**** Stage 1 testing:  single stream/data-ID

-***** EJFAT LB + reassembly (RA) engine overall performance data-rate dependence.
+**** parallelize writing of raw data files
-***** EJFAT LB + RA engine performance dependence from the EJFAT packetizing engine MTU settings
+**** distribute raw data across multiple compute nodes for calibration skims
-**** Stage 2 testing: multi-stream/data_ID
+**** 1 Gbs at hi-luminosity
-***** Use EJFAT LB firmware that supports load balancing of multiple source/data_IDs.
+**** Control Plane
-***** EJFAT LB + RA engine performance as an event builder (i.e. source ID aggregator), a capability to send all available data_ID's with the same tick (time frame) to a single destination. NB Hall-B FT calorimeter and hodoscope setup is capable of sending up to 12 data streams.
