The switching function is based on a central memory bank associated with its data path control. Each switch port stores received frames in this memory, passing a buffer pointer to the forwarding port’s transmitter. The switch uses cut-throughrouting to route frames from the receiving port to the transmitting port, providing the transmit port is free, without waiting for the end of the frame to be received. This provides a low-latency data path within the switch. The frame can be temporarily stored in the memory bank but only if the transmit port is busy.
