I hadn't quite understood this slide during the class. Could someone please explain why the transmission of the tail can continue if the output link is blocked? Wouldn't we end up breaking up the original message into incoherent sub-packets?
@fleventyfive If the output link is blocked the tail can still continue up until the point as which the head is blocked (as long as the buffer for the switch contains the necessary space). Think of it as similar to wormhole switching in this case where the tail will catch up to the head.
