ATM s w itches and links have been investigated for use as the event building fabric for future data acquisition architectures and will be used in CEBAF' s CLAS detector. To avoid contention problems and cell-loss, a linked dual token passing a Igorithm has been devised, with two different types of tokens being passed through the sw itch, This algorithm leads to a ' barrel shifter' type of parallel d ata transfer. We describe the hardware architecture and the dual token algorithm, and presentdoi:10.1142/9789814447188_0075 fatcat:kjp3ujm5szfqrh5ijolqddnowe
