Data Frame Forwarding: Store-and-Forward, Cut-Through, and Fragment-Free Switching

Every switch has to decide exactly when to start forwarding a frame — wait for the whole thing, or start moving it the instant enough information is available. That decision defines the three switching methods every CCNA and CCNP candidate needs to know: store-and-forward, cut-through, and fragment-free. Each represents a different trade-off between reliability and...
