Switching device

摘要

A switching device comprising a plurality of ingress ports and a plurality of egress ports. The switching device is arranged to receive data packets through said ingress ports and to forward received data packets to respective ones of said egress ports. The switching device is further arranged to: determine a first time at which a first cell of a selected data packet is to forwarded to one of said egress ports, determine a further time at which a respective further cell of the selected data packet is to be forwarded to said one of said egress ports, store data indicating that said respective further cell is to be forwarded at said determined further time, forward said first cell at said first time, and forward said further cell of said selected data packet at said determined further time.

1. An apparatus comprising a plurality of ingress ports and a plurality of egress ports, the apparatus being arranged to:
receive through the ingress ports a data packet comprising a plurality of cells; and schedule, in a single scheduling operation, respective times to forward each of the plurality of cells of the data packet to at least one of the egress ports, the single scheduling operation comprising:
determining a first time slot at which a first cell of the selected data packet is to be forwarded to the at least one of the egress ports, the first time slot being in one of a first phase or a second phase;determining a plurality of further time slots at which respective further cells of the plurality of cells are to be forwarded to the at least one of the egress ports, each respective further time slot being in the same phase as the first time slot; wherein cells of different data packets are forwarded in an interleaved manner.
