摘要： A pipeline scheduler provides a minimum bandwidth guarantee by transporting cells from an input port to an output port in a two-phased approach. Cells that conform to a minimum cell rate (MCR) are selected from queues at the input port and arranged into supercells for transport to the output port, followed by nonconforming cells, to guarantee fairness by using scheduling modules to build the supercells first for conforming cells, and then for nonconforming cells. Reservation vectors are used to permit the same time slot of the next frame to be reserved by a first queue, and the same time slot of the following time frame to be held for reservation by a second queue, to ensure equal time slot access by the first and second queues over successive time frames.

摘要： The present invention provides a system and method for enabling the synchronization of a switch and an interface device. Based on a comparison of cell sequence numbers included in cells received from the interface device to a current cell time within the switch, cell time adjustment information can be transmitted to the interface device. The cell time adjustment information is used by the interface device to determine the cell sequence number that is included in cells transmitted to the switch.
