Ping and Traceroute

-

 Information is passed used the internet through multiple routers. As Vahid & Lysecky state, “The Internet is the most popular (but not the only) computer network today” (3.5). The internet is a vast network of computers using routers and ISPs to pass along information. When reviewing the ping times and packets that were sent, I noticed each set of commands sent 4 packets each. In my examples, no packets were lost in the ping process (see notes below).

When completing the traceroute process, I was able to get a much more detailed view of how the information was being processed from router to router. Also, there were failures along the way in the server that was traced to China. Due to the distance, I can see why information might time out, reach firewalls, or possible just hit disconnected servers or servers that are communicating too slow to really process the information. With the traceroute command it was easy to tell that my ping was failing in the middle of the transfer and was having to hop to different routers. Also, one cause could be the availability of routers to a specific area of the world.

Also, the further away the router was, the longer the time typically took for the packet to be received. When troubleshooting connectivity issues, the traceroute and ping could both be very useful. Ping would let you know if the other server was communicating at all. A very high ping time could also indicate that their server was having ISP connectivity issues possibly, or some other outside circumstance causing the transfer of data to be slow. The traceroute feature was great for pinpointing exactly where the information was failing. This might help troubleshoot whether the user was having the problem, the server being sent to was having a problem, or maybe something is down with the connectivity along the way.

This exercise was a great way to show just how many steps information takes to process when on the internet. I know we all seem to think that information is an A to B process when it comes to the internet, because we don’t see the information being transferred. This example shows just how many routes the information takes to get processed when a request is entered on your computer and then shown on your screen in a web browser.

Ping and Traceroute Examples:

This screenshot is of a site in Australia. Four packets were sent with no losses and the ping time was much lower, ranging from 18ms to 23ms:


This screenshot is from the .au website and had no failures:


This screenshot is a ping of TokyoLife server in China. Four packets were received with no losses. However, the ping was much higher ranging from 215-234ms:


This screenshot is from the website in China and had 6 failures throughout the trace:


This screenshot is from a ping of Google.com. Four packets were sent and 4 were received, with no losses. The range in time for each packet was 78 to 82ms:


The following trace route is for Google.com. There were 18 hops completed and all went through different routers. No failures occurred and the first line was my home router and the second line was my ISP router.

Employee Management System - Simple Project

  The employee management system project is designed to take user input and store the information as variables for later use. As Miller, Vahid, and Lysecky point out, a variable “is used to remember a value for later use" (2015). Creating the variables of employeeName, employeeSSN, employeePhone, employeeEmail, and employeeSalary were to hold the information to display later in the program. Variable types were string with the exception of the salary input that was set as an integer.             Repetition was very useful in writing this code. Each line was the same just changing the variable name and type in the string. Employee salary was the only line that had an addition with the sep= function to remove the space after the $ sign in the code. This was used for appearance purposes. Setting the variables to strings allowed the user to enter dashes if needed and parenthesis if desired for the phone number. Setting the variabl...

Explicit and Implicit Variables

-
  What is a Variable? Using implicit or explicit variables is an important decision when choosing what language to use when writing a program or starting to code. In simplest terms, a variable is used to remember a value for later use. The way different programming languages use variables is important for programmers to keep in mind when choosing how to code variables. Implicit variables are when the compiler chooses the type of output and explicit variables are when the programmer pre-assigns variables to have a specific output. Examples of Variables Each can be useful depending on the program that is being written. Boudreau points out that implicit variables can often be easier to use in programming and that sometimes the results can be just fine. However, leaving the compiler making that decision making on an assumption can often lead to problems. Explicit assigning of variables gives a more specific output and result and can be much more reliable. Depending on the lan...

Creating Tables in MySQL

  Creating Tables in MySQL           Creating tables in MySQL is important so that a user can add information, delete information, and update an entry using SQL statements. Also, a final statement was created to join all three tables demonstrating the relationships between the three tables. The INSERT function was used to add rows to the first table named tbldvdtitles. The information was inserted and the code and the results are pictured below: MySQL instructions were used by Oracle to guide the use of MySQL. The next table was a table called tbldvdActors with the information inserted and results below: Updating and deleting rows were part of the requirements for the interactive assignment and the following code was used: A third table was created to describe the relationships between actor ID and the ASIN number for each movie and the results were as follows: Joining all three tables was the last step and the results were as follo...
