To write a python program to perform sliding window protocol
ALGORITHM :
Start the program.
Get the frame size from the user
To create the frame based on the user request.
To send frames to server from the client side.
If your frames reach the server it will send ACK signal to client otherwise it will send NACKsignal to client.
Stop the program.
CLIENT PROGRAM :
## Developed : SYED ADIL BASHA## Reg no : 212221043008importsockets=socket.socket()
s.bind(('localhost',8000))
s.listen(5)
c,addr=s.accept()
size=int(input("Enter number of frames to send : "))
l=list(range(size))
s=int(input("Enter Window Size : "))
st=0i=0whileTrue:
while(i<len(l)):
st+=sc.send(str(l[i:st]).encode())
ack=c.recv(1024).decode()
ifack:
print(ack)
i+=s
SERVER PROGRAM :
importsockets=socket.socket()
s.connect(('localhost',8000))
whileTrue:
print(s.recv(1024).decode())
s.send("acknowledgement recived from the server".encode())
SERVER OUTPUT :
CLIENT OUTPUT :
RESULT:
Thus, python program to perform stop and wait protocol And Sliding Window Protocol was successfully executed.
