EX.NO:1 Implementation of Stop and Wait Protocol and Sliding Window Protocol

AIM:

To write a java program to perform sliding window.

ALGORITHM:

1.Start the program.

2.Get the frame size from the user

3.To create the frame based on the user request.

4.To send frames to server from the client side.

5.If your frames reach the server it will send ACK signal to client otherwise it will send NACK signal to client.

6.Stop the program

Program :

import java.net.*;

import java.io.*;

import java.rmi.*;

public class slidsender

{

public static void main(String a[])throws Exception

}

System.out.print(“nDo you wants to send some more frames : “);

ch=in.readLine(); p.println(ch);

}

while(ch.equals(“yes”));

s.close();

}

}

OUTPUT:

//SENDER OUTPUT

Enter the no. of frames : 4

Enter 4 Messages to be send

how r u

Vtu

i am fine

how is evryone

Acknowledgment received for 4 frames

Do you wants to send some more frames : no

//RECEIVER OUTPUT

The received Frame 0 is : hiii

The received Frame 1 is : how r u

The received Frame 2 is : i am fine

The received Frame 3 is : how is everyone
