What is difference between Store-and-Forward, cut-through,
Fragment-Free Method?
Answers were Sorted based on User's Feedback
Answer / guest
these are all the switch types based on their working....
1. Cut through: the switch checks the frame only upto
13bytes and as it learns the destination address, it starts
forwarding the frame....lowest delay but is less reliable as
there is no error checking.
2. Fragment Free (Modified Cut-through): in this switches
checks the frame upto 64 bytes looking for any errors.if not
found then starts forwarding it to the destination....little
more delay than cut-through-and is some about reliable also.
3. Store and forward: in this type, the switch firstly
stores the entire frame in its buffer memory, after that it
runs error checking mechanism (CRC)to check the integrity of
the frame....if any errors are found it is dropped otherwise
forwarded to the destination. Highest delay and is highly
reliable.....
