摘要: A fault tolerant queue system for buffering data in a packet switch with common buffer memory one or more output ports from the uses number of pointers identifying storing positions memory. Multiple copies same pointer are handled controlled way by using multiple list where included respective recorded. maintenance function checks that agrees value recorded pointer. The cyclically all and appurtenant positions, at time. This is preceded an initiation procedure during which taken out operation filtering flow lists queueing to returned idle list, until has been emptied each copy question. Thereupon, question compared list. can thereafter work accordance operating modes performing cyclical control.
