Data Distribution components for the ALICE O2

Data Distribution

Data Distribution processes (O2 devices) implement SubTimeFrame building on FLPs, and TimeFrame aggregation on EPNs.

Components

Components of the data distribution chain are:

• StfBuilder (FLP): The first process (O2 device) in the chain. It receives readout data and once all HBFrames are received, forwards the STF to the next device in the chain.
• StfSender (FLP): Receives STF data and related results of local processing on FLP and performs the TimeFrame aggregation.
• TfBuilder (EPN): Receives STFs from all StfSender processes, creates the full TimeFrame and forwards it to global processing.
• TfScheduler (service): Service discovery and active TimeFrame steering.

Use cases

Standalone, testing and development use-cases are discussed here.
