Two Transmission Method in Packet Switching

1.Store-and-forward

• Entire packet must arrive at router before it can be transmitted on next linnk

2.Cut-through

• A modified virtual-circuit switching
• Minimum delay in transmitting the packet
• Useful for speech transmission (delay requirement)
• Useful in virtually error-free transmission
• Useful in case data size is too big
