C Program to calculate the Round Trip Time (RTT)

Given an Url address of any website; the task is to calculate the round trip time of a website.

Round Trip Time(RTT) is the total time or the length of a time which is taken to send a signal plus the time taken to receive the acknowledgement of that signal to be received. This time also consist of the propagation times between two points of a signal.

An end user can determine his/her round trip time from an IP address by pinging that address.

The Round Trip time’ result depends upon the following reasons −

The Transmission medium.
The presence of Interface in the circuit.
Number of nodes from the source to the destination.
Amount of traffic.
Physical Distance from the source to the destination.
Nature of the transmission medium(wireless, fiber optic, etc.).
Number of requests.
Presence of interface in the circuit.

Generally the duration of Round Trip Time will be in milliseconds and we displaying output in Seconds.

Example

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

Approach we will be using to solve the given problem −

Take the input string of the URL whose RTT(Round Trip Time) we want to calculate.
Record the time before requesting the URL and store it into a variable.
Send the request.
Record the time after receiving acknowledgement.
Compare both the 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
