What types of messages flow across an SDN controller’s northbound and southbound APIs? Who is the recipient of these messages sent from the controller across the southbound interface, and who sends messages to the controller across the northbound interface?

Answer:

Explanation:

Pink: Down 5 then left 2.

Yellow: Left 3 and down 2.

Green: Right 7, down 4 and left 1.

Purple: Up 6 and left 9.

Red: Left 7, down 5 and left 1.

You can do the last one, blue :)

Answer:

Explanation:

u=up, d=down, r=right, l=left

yellow: l3d2

pink: d5l2

green: r7d4l1

purple: u6l9

red: l7d5l1

blue: r2u7l5

Answer:

50 ms (milliseconds) will be taken in total to take the entire file by user.

Explanation:

In Computer networks, propagation delay is defined as the time in which a packet is sent from sender to receiver completely. It is computed by taking the ratio of link length and propagation speed.

We know that:

BDP(in bits) = total bandwidth (in bits/sec) * trip time(in sec)

Now according to given condition we have:

Bandwidth = R = 10 Mbps = 10,000,000 bps

BDP = 500,000 bits

For finding Propagation Delay:

Propagation Delay = BDP/ R

Propagation Delay = 500,000/10,000,000 sec

Propagation Delay = 0.05 sec

Converting in milliseconds:

Propagation Delay = 50 ms

Hence. the delay would be 0.05 seconds and in milliseconds they will be equal to 50 ms

A potential cause of this issue with FTP is that the server is not able to resolve the client IP address.

What is FTP?

FTP is an acronym for file transfer protocol and it can be defined as a type of server that is designed and developed to store and provide files for download and sharing between two or more users on a computer system.

In this scenario, the user is most likely experiencing issues when trying to transfer files through the file transfer protocol (FTP) because the server is not able to resolve the client IP address, which is the address of the recipient of the file.

Answer:

The solution is provided in the explanation section.

Detailed explanation is provided using comments within the code

Explanation:

import java.util.*;

public class Main {

//The Bubble sort method

public static void bb_Sort(int[] arr) {  

   int n = 10; //Length of array  

   int temp = 0; // create a temporal variable  

   for(int i=0; i < n; i++){  

         for(int j=1; j < (n-i); j++){  

           if(arr[j-1] > arr[j]){  

               // The bubble sort algorithm swaps elements  

               temp = arr[j-1];  

               arr[j-1] = arr[j];  

               arr[j] = temp;  

             }  

         }            

         }  

        }

 public static void main(String[] args) {

   //declaring the array of integers

   int [] array = new int[10];

   //Prompt user to add elements into the array

   Scanner in = new Scanner(System.in);

   //Use for loop to receive all 10 elements

   for(int i = 0; i<array.length; i++){

     System.out.println("Enter the next array Element");

     array[i] = in.nextInt();

   }

   //Print the array elements before bubble sort

   System.out.println("The Array before bubble sort");

   System.out.println(Arrays.toString(array));

   //Call bubble sort method

   bb_Sort(array);  

   System.out.println("Array After Bubble Sort");  

   System.out.println(Arrays.toString(array));

 }

}

I hope it will help you!

Explanation:

Following are the python program to use the loop to count the number of pets until the user enters the "rock":

Program:

c = 0#defining a variable c that initilzes with 0

p = input()#defining a variable p that input value

while p != 'rock':#defining a loop that check p value not equal to rock

  c += 1#using c variable for counts total number of pets

  print('You have a %s with a total of %d pet(s)' %(p,c))#print total number of pet

  p = input() #input value

Output:

Please find the attached file.

Program Explanation:

• Defining a variable "c" that is initialized with 0, which is used to count input values.
• In the next line, a "p" variable is declared as the input value from the user end.
• A while loop is declared to check that the p-value is not equal to 'rock'.
• Inside this loop, the "c" variable is used for counting the total number of pets, and a print method is used to print the total number of pets.
• Another input method is used that works until the user inputs the value that is "rock".
