Forwarding mode change function
In this device, cut-through mode and store-and-forward mode can be selected as a switching method.
Cut-through mode
Top portion of the packet is input to this device and then the packet is delivered from the transfer destination
port. Transfer is executed without waiting for the entire packet to be input, therefore delay of the packets
associated with transfer can be minimized.
Store-and-forward mode
Entire packet is input to this device and then the packet is delivered from the transfer destination port.
Points to be noted
When cut-through mode is selected, latency is can be reduced and error packets are relayed. In case of
store-and-forward mode, error packet is not transited even if it is input. On the other hand, latency is
lengthened than the cut through mode due to accumulation of packet data.
