Symmetric switching allows connection between ports of unlike bandwidth and does not require memory buffering.

Memory buffering is used to prevent a bottleneck when ports of different bandwidth are connected on a symmetric switch.

The latency can be reduced if the switch utilizes the store and forward method of switching. Store and forward is better for error detection.

The cut-trough method of switching is faster because the switch forwards the packet to the destination as soon as it reads the destination address.
