PP Presentation

• In TFTP a seperate ACK is always sent when a frame arrives. This is a half-duplex xmission. If transmission were full-duplex, we could improve throughput via piggy backing.
• This involves adding a frame ack code to the next outgoing frame. This means hold up the xmission of the ack till the next frame is ready. If we wait beyond the timeout, the rexmission occurs.
