as they can buffer incoming data until it can be transmitted further.
It should be noted, however, that the buffering can result
in serious delays, especially in congested networks. In fact, it
is shown in [14] that hub-based networks outperform switched
networks at low loads, due the lack of switching delays. One
method to alleviate some of the switching delays is to use
pass-through switches instead of store-and-forward switches.
Store-and-forward switches buffer an entire incoming packet
before attempting to retransmit it, also allowing the switch
to examine the packet and check it for errors.
