Future Plan
- 1. Current simulation can produce buffer size and data flow
timing for ALICE-DAQ simulation
- 2. The results depends on service time in FLP and EPN, and
maximum buffer size
- 3. More refine behavior on FLPs and EPNs internal data flow are
needed
- 4. Validation against previous real data
