Packet Traveling

Packet Traveling - Title

 

If you’re reading this blog, then you are no doubt already familiar with the wondrous creation that is the Internet. The Internet allows computers from all over the world to speak to each other.

When data leaves your computer, it is grouped into small chunks called Packets. These packets are essentially little envelopes that carry data across the Internet.

This article series is going to explain everything that happens to get one of these Packets from one side of the Internet to the other. We will look at each device and every step involved with a packet traveling across the Internet.

First, we’ll take a look at some background information on each separate function of network communication. Then we’ll take a look at the individual devices that perform each function. We will then tie everything together as we look at everything that happens for communication to happen between two computers with various interconnected devices.

Packet Traveling

After reading through this article series on Packet Traveling, you will be able to understand and explain all the different events which occur in sending data from one side of the Internet to the other.

  7. Ed Harmoush,

    Thank you so much for the time and effort you have put into this blog and whole site.
    The articulation and attention to detail, where needed (which is important to note) is great and unlike any other resource I have found online.

    I am actually a System Engineer, and sometimes I need a refresh. There are so many articles out there that don’t achieve the level of quality in their blogs or answers because they lack the simplistic language and current examples.

    Thank you so much again for the time and effort you have put into it. For what it is worth, I have booked marked your site (yes, I still book mark ;P ) for later referencing.

    Cheers,
    Nicole

  8. Hi Ed,
    I am so impressed with your blog & your video, I have been reading all sort of different manuels which didn’t provide such level of understanding, more especially emphasize on the 3 different tables (ARP, MAC ADDR and ROUTING Tables). you might have read on them, but such key to know that they are the keys to the troubleshooting exposure. This is the key element no one has addressed in my time of stuying ccna, ccnp R&S, one needs to have in mind when troubleshooting. Your article is very and very helpful, I have been having serious issues in troubleshooting, after reading, all have fallen into place now, BIG THANK YOU!!!

  13. Vipin Garg says:

    Awesome sir..thanks a lot

  14. good information sir,
    sir, I have a doubt can I clarify few things

  15. when you talk about aaaa being mac address of hostA, it is on of host’s nic mac or some mac representing entire host A

    • Hi Andy,

      The MAC address is the identify of a particular NIC. Most end-hosts only have one NIC, so in such cases, aaaa represents the single MAC address for Host A. If, however, Host A had multiple network interface cards, then each would have their own MAC address.

    Great job. Clear. Concise. Thanks for taking the time to do this.
