The DAQ and Timing Hub is an ATCA hub board designed for the Phase-2 upgrade of the CMS experiment. In addition to providing high-speed Ethernet connectivity to all back-end boards, it forms the bridge between the sub-detector electronics and the central DAQ, timing, and trigger control systems.

CMS Phase-2 DAQ and Timing Hub -- Prototyping results and perspectives
/ Amoiridis, Vasileios (CERN) ; Behrens, Ulf (Rice U.) ; Bocci, Andrea (CERN) ; Branson, James (UC, San Diego) ; Brummer, Philipp Maximilian (CERN) ; Cittolin, Sergio (UC, San Diego) ; Da Silva Gomes, Diego (Rio de Janeiro State U.) ; Darlea, Georgiana Lavinia (MIT) ; Deldicque, Christian (CERN) ; Dobson, Marc (CERN) et al.
This paper describes recent progress on the design of the DAQ and Timing Hub, or DTH, an ATCA hub board intended for the Phase-2 upgrade of the CMS experiment. Prototyping was originally divided into multiple feature lines, spanning all different aspects of the DTH functionality. [...]

The CMS Data Acquisition - Architectures for the Phase-2 Upgrade
/ Andre, Jean-Marc Olivier (Fermilab) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Brummer, Philipp Maximilian (CERN) ; Chaze, Olivier (CERN) ; Cittolin, Sergio (UC, San Diego) ; Contescu, Cristian (Fermilab) ; Craigs, Benjamin Gordon (CERN) ; Darlea, Georgiana Lavinia (MIT) ; Deldicque, Christian (CERN) et al.
The upgraded High Luminosity LHC, after the third Long Shutdown (LS3), will provide an instantaneous luminosity of $7.5\times10^{34}$ cm$^{-2} s^{-1}$ (levelled), at the price of extreme pileup of up to 200 interactions per crossing. In LS3, the CMS Detector will also undergo a major upgrade to prepare for the phase-2 of the LHC physics program, starting around 2025. [...]

Trigger-less readout and unbiased data quality monitoring of the CMS Drift Tubes muon detector
/ Migliorini, Matteo (INFN, Padua) ; Pazzini, Jacopo (INFN, Padua ; Padua U.) ; Triossi, Andrea (INFN, Padua ; Padua U.) ; Zanetti, Marco (INFN, Padua ; Padua U.) ; Zucchetta, Alberto (INFN, Padua ; Padua U.)
/CMS Collaboration
The CMS experiment 40MHz data scouting project is aimed at intercepting the data produced at the level of the detectors' front-end without the filters induced by hardware-based triggers. A first implementation is realized by the trigger-less reading and processing of a fraction of the Drift Tube (DT) muon detector, equipped with a preliminary version of the so-called Phase-2 Upgrade on-detector electronics boards.

Online data handling and storage at the CMS experiment
/ Andre, Jean-marc Olivier (Fermilab) ; Andronidis, Anastasios (Ioannina U.) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Chaze, Olivier (CERN) ; Demiragli, Zeynep (MIT) ; Dobson, Marc (CERN) ; Dupont, Aymeric (CERN) ; Erhan, Samim (UCLA) ; Gigi, Dominique (CERN) et al.
During the LHC Long Shutdown 1, the CMS Data Acquisition (DAQ) system underwent a partial redesign to replace obsolete network equipment, use more homogeneous switching technologies, and support new detector back-end electronics. The software and hardware infrastructure to provide input, execute the High Level Trigger (HLT) algorithms and deal with output data transport and storage has also been redesigned to be completely file- based.

MiniDAQ-3: providing concurrent independent subdetector data-taking on CMS production DAQ resources
/ Amoiridis, Vasileios (CERN) ; Behrens, Ulf (Rice U.) ; Bocci, Andrea (CERN) ; Branson, James (UC, San Diego) ; Brummer, Philipp Maximilian (CERN) ; Cano, Eric (CERN) ; Cittolin, Sergio (UC, San Diego) ; Quintanilha, Joao (CERN) ; Darlea, Georgiana Lavinia (MIT) ; Deldicque, Christian (CERN) et al.
The data acquisition (DAQ) of the Compact Muon Solenoid (CMS) experiment at CERN, collects data for events accepted by the Level-1 Trigger from the different detector systems and assembles them in an event builder prior to making them available for further selection in the High Level Trigger, and finally storing the selected events for offline analysis. In addition to the central DAQ providing global acquisition functionality, several separate, so-called "MiniDAQ" setups allow operating independent data acquisition runs using an arbitrary subset of the CMS subdetectors.
