Cut-through

In computer networking, cut-through  is a method for 

packet switching systems, wherein the switch starts 

forwarding a frame (or packet) before the whole frame 

has been received, normally as soon as the destination 

address is processed. Compared to store and forward, 

this technique reduces latency through the switch, but 

decreases reliability; corrupted frames are potentially 

forwarded.

Adaptive switching dynamically selects between cut-

through and store and forward behaviors based on 

current network conditions.

Pure cut-through switching is only possible when the 

speed of the outgoing interface is equal to the incoming 

interface speed.
