“…Partial loss of raw data leads to collecting corrupted events that cannot be reconstructed. A prior study demonstrated that collection of complete events in these conditions can be maximised using a centralised throttling mechanism [2]. The throttling decision is based on buffer and link occupancy in the DAQ network and is distributed to CRI boards to prevent uncontrolled data loss.…”

The Compressed Baryonic Matter (CBM) experiment is designed to handle interaction rates of up to 10 MHz and up to 1 TB/s of raw data generated. With triggerless streaming data acquisition in the experiment and beam intensity fluctuations, it is expected that occasional data bursts will surpass bandwidth capabilities of the Data Acquisition System (DAQ) system. In order to preserve integrity of event data, the bandwidth of DAQ must be throttled in an organised way with minimum information loss. The Timing and Fast Control (TFC) system provides a latency-optimised datapath for throttling commands and distributes a system clock together with a global timestamp. This paper describes a prototype design of the system with focus on synchronisation and its evaluation.
