QUESTION 1Compare the benefits of the RDT3 protocol vs. RDT1 and RDT2Reliable data transfer protocol provides the best services with no guarantee that data canreached their destination or not. This data transfer protocol will help for providing the bestservices to share information form one node to another (Jiang, 2018). It is importantcharacteristics of unreliable channel that will determine the complexity of data transfer protocol. Comparison between Rdt1, Rdt2 and Rdt3RDT1RDT2RDT3It is reliable datatransfer form fromone channel toanother by usingnetwork. There is no bit errorand no packet lossin the system.RDT1 have separateFSM for sender andreceiver. Receiver read all thedata from channel.Channel with the biterrors. Sender In RDT2, there is someerror in signals, ifsending the messagesformfrom one place toanother.RDT2 has checksum todetect the bit errors insystem. There is no duplicationof data and is deliveredin FIFO order. Reliable data transfer3 is useful to delivertheacknowledgementand data packet in aproper manner.It is continuouslysending packets formfrom one place toanother and it canreceive uncorruptedpacket.In RDT3, channelcan loss data in theform of packets.QUESTION 2Discuss whether a timer is required for round-trip delay messages under protocol RDT3In RDT3, Thethe round trip time is basically when the data from one device to anotherand having receipts of its acknowledgement. Round trip timer is a major function in the RDT3protocol (Montella,Ruggieri and Kosta,2018). This timer will is used for ensuring that data is1
