12 th – 16 th April, th CBM Collaboration Meeting 27 Data Aggregation on separate chip - Communication hub Motivation:  Data Aggregation: In most cases 2,4, or 8 CBM-XYTER chips (FEBa2, FEBa4, FEBa8, resp.) can be aggregated to fill a 2.5 Gbps link  Increase the bandwidth available per link  Reduce the number of Optical Links Schemes:  Embedded (aggregation integrated in CBM-XYTER)  Data aggregation and Traffic Management with a separate Communication Controller Asic  Communication ‘hub’  Clock Distribution  Slow control traffic  Data Readout traffic 6 DAQ/FLES WG Slide: P.
