Part B: Ston-and-Wait File Transfer In this part, we will develop a simple unidirectional file transfer application over UDP Our goal would be to make it as simple as possible, while ensuring correctness/reliability of the file transfer. It will be built along the lines of the Stop-and-Wait reliable transfer protocol (Rdt 3.0) that we studied in Chapter 3. The requirements that the application (which we will call sfp) must satisfy are described below The sftp application requirements: The data transfer will be unidirectional- from the client to the server, although the acknowledgements would need to be sent from the server to the client. To transfer a file, the user (client) should call sfipClient where server_ipaddress is the IP address of the server in dotted decimal format. The stop-and-wait version of the protocol that you will implement has some similarities with the Trivial FTP (or TFTP) protocol, that also runs over UDP.1 In a way, the sftp application that you will implement can be viewed as a simpler version of TFTP Part B: Ston-and-Wait File Transfer In this part, we will develop a simple unidirectional file transfer application over UDP Our goal would be to make it as simple as possible, while ensuring correctness/reliability of the file transfer.
