Switch Processing
LAN Switching / Ch. 7 - Ethernet LAN Switching Concepts
| Switching Method | Description |
|---|---|
| Store-and-forward | The switch fully receives all bits in the frame (store) before forwarding the frame (forward). This allows the switch to check the FCS before forwarding the frame. |
| Cut-through | The switch forwards the frame as soon as it can. This reduces latency but does not allow the switch to discard frames that fail the FCS check. |
| Fragment-free | The switch forwards the frame after receiving the first 64 bytes of the frame, thereby avoiding forwarding frames that were errored due to a collision. |
