stop and wait protocol socket program in c

Complete copyrights to all work purchased. A program that does not compile and run receives a zero.Ĭomplete and fully-functional working program(s) in executable form as well as complete source code of all work done. The minimum system calls you will need are: socket() bind() gethostbyname() gethostname() sendto() recvfrom() Your grade will be based on the correct implementation of this assignment. I suggest your implementation of this function simply writes the message received to the screen. The call to_network_layer() passes the received data to the above layer. For your implementation of this function, I suggest prompting the user for a value to send. The call from_network_layer() obtains data to send. You may not have global variables! The sender executable and the receiver executable should each execute on a different machine.

All variables should be declared in main() and passed to the appropriate functions.

Each main () should behave as a driver program. Your variables declarations and formal parameters will differ from the protocol. By layout I mean the same function calls (your code provides the functions), e.g., from_network_layer() and the same while loop. One main() should have the same layout as the sender of the protocol, and the other main() should have the same layout as the receiver of the protocol. One program should model the sender and the other should model the receiver given in the protocol handout. You also have a handout with TCP/IP system calls for sending and receiving UDP datagram.

This protocol can be found in the handout of protocols. Your assignment is to implement the Stop-and-Wait Protocol 2 (assumes error free transmission). In particular, the services provided to the network layer and the physical layer services used by this protocol. Complete understanding of protocol 2 of handout Able to implement round trip message passing Use of UDP datagrams Use of sockets for I/O Understanding the role of ports and IP addresses for socket programming Understanding of the data structures involved using the socket library Understanding distributed processing (compared to multiprocessing) Understanding of the Stop-and-Wait Protocol Better understanding of protocol architecture.

Project 3: Stop-and-Wait Protocol Due date: June 19th, 2002 When this project has been completed, the following outcomes should be realized.
