C program to calculate round trip time (RTT)

Given the URL address of any website; the task is to calculate the round trip time to the website.

Round trip time (RTT) is the total time or length required to send a signal, plus the time required to receive an acknowledgment of that signal. This time also includes the propagation time between signals.

The user can determine his/her round trip time by pinging the IP address.

The result of the round trip time depends on the following reasons:

• Transmission medium.
• Interface in the circuit.
• The number of nodes from source to destination.
• Traffic volume.
• The physical distance from source to destination.
• The nature of the transmission medium (wireless, optical fiber, etc.).
• Number of requests.
• Interface in the circuit.

Typically, the round trip time duration is in milliseconds and we display the output in seconds.

Example

Input: www.tutorialspoint.com
Output: Time taken:0.3676435947418213
Input: www.indiatoday.in
Output: Time taken:0.4621298224721691

We will use the following method to solve the given problem −

• Get the input string of the URL for which the RTT (round trip time) is to be calculated.
• Record the time before the URL was requested and store it into a variable.
• send request.
• Record the time after receiving the confirmation.
• Comparing these two times, we will get the RTT.

Algorithm

Start
   Step 1 -> import time
   Step 2 -> import requests
   Step 3 -> define a function def roundtriptime(url):
      Set t1 = time.time()
      Set req = requests.get(url)
      Set t2 = time.time()
      Set t = str(t2-t1)
      Print Time taken
   Step 4 -> Initialize url = "http://www.tutorialspoint.com"
   Step 5 -> Call function roundtriptime(url)
Stop

Example

import time
import requests
# Function to calculate the roundtriptime
def roundtriptime(url):
   # time when the signal is sent
      t1 = time.time()
      req = requests.get(url)
   # time when the acknowledgement
   # is received
      t2 = time.time()
   # total time taken
      t = str(t2-t1)
      print("Time taken:" + t)
   # url address
      url = "http://www.tutorialspoint.com"
      roundtriptime(url)

Output

Time taken:0.3676435947418213
