WebFor connection-oriented service provided by TCP, it is necessary to have a reliable data transfer (RDT) protocol to ensure delivery of all packets and to enable the receiver to deliver the packets in order to its application layer. ... Stop-and-wait RDT protocols have poor performance in a long-distance connection. At best, the sender can only ...

WebSuppose an application uses rdt 3.0 as its transport layer protocol. As the stop-and-wait protocol has very low channel utilization (shown in the cross-country example), the … Webpropagation delay. The transmission diagram below shows the operation of rdt 3.0 when there are no bit errors and losses. Due to the nature that it stops the data packet transmission and waits until receiving the acknowledgement packet to send another, rdt 3.0 is also referred to as the stop-and-wait protocol.
