Implementation of Sliding Window Program using C | Network Lab Exercises

Step 1: start the program.

Step 2: Open the input file in read mode.

Step 3: Read the size of the window

Step 4: Select randomly the number of packets is to be transferred.

Step 5: Read the content of the input file.

Step 6: Transfer the packet until it reaches the maximum defined size.

Step 7: Resume the window size and repeat the above two steps until packets in.

Step 8: Close the file.

Step 9: Stop the program.

C Program To Implement Sliding Window

#include #include main() int i,m,n,j,w,1; char c; FILE*f; f=fopen("text.txt","r"); printf("window size"); scanf("%d",&n); m=n; while(!fof(f)) { i=rand()%n+1; j=i; 1=i; if(m>i) { m=m-i; if(m>0) { printf("\n"); while(i>0 & !feof(f)) { c=getc(f); printf("%c",c); i--; } printf("\n%d transferred"j); if(j>3) printf("\n 1 acknowledgement received"); else printf("\n acknowledgement received",j+1); } } m=m+j-1; } }
