One type of frame switching uses low-latency forwarding and then switches to a higher-latency error checking mode when an error threshold is exceeded. What is the name of this frame switching mode?
A. Store and forward
C. Adaptive cut-through
Adaptive cut-through is a modified form of cut-through switching in which the switch waits for the collision window (64 bytes) to pass before forwarding. It means that each frame will be checked into the data field to make sure no fragmentation has occurred.
Why not C? I read from ICND and INTRO that there are only three forwarding mode for cisco switch. Two primary are cut-through and store and forward, and fragment-free is kinda combine those two. what is this Adaptive cut-through? and what is the difference between Adaptive cut-through and fragment-free?
