Packet Traveling - How Packets Move Through a Network

This video will illustrate everything that happens to describe how packets travel through a network. Specifically, we will look at every step to get a packet from a host, through a switch, then a router, then another switch, and finally to another host.
This video is the series finale to an article series on Practical Networking.net that explains everything you need to know to understand how data moves through the Internet. You can read the Packet Traveling series here:

*UPDATED VERSION OF THIS VIDEO: **kzbin.info/www/bejne/j3uqeIyBdrtnpqM* That is the new final video of a 13 part video series discussing Networking Fundamentals. You can see the full series here: kzbin.info/aero/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi 👇 Hello, This video is the first video I ever published to KZbin. Initially, I didn't even mean to create a consistent KZbin presence, this was simply a topic that I felt was better taught visually. All that said, I've come a long way with video and audio recording quality. I know there are a bunch of issues with the audio in this video, but please understand I was very new at recording videos when I published this in 2016. All my newer content is much, much better quality =) Hope you got a lot out of this, and if you did, I would highly recommend the series I linked above, as it's a much more thorough and expanded version of how Networking works. Cheers! -Ed Practical Networking .net

Network engineer here. This is phenomenal, man. No matter how far I get into this, I always come back to solidify the basics. This is very simply explained, but straight to the point. The fact you included the switch learning the MAC of the ARP sender is a thing I have not seen in many videos. I hope to start making videos like this soon!

@@dawidnazarko926 Sorry, somehow I've only just seen this comment! I'm afraid I don't have any suggestions on resources for Docker networking. As for practical assignments, I usually suggest students rebuild the lab topologies they see in videos in GNS3 or Packet Tracer and validate everything they've learned against real gear. That way they aren't just taking the instructor's word for it, but are actually proving it to themselves.

[@rohithk011]

A big thumbs up from me ... Although I have one question. In step 2 How does the PC A know or PC will figure out that we need to send ARP frame to 11.11.11.1 instead of 22.22.22.40 ?

[@PracticalNetworking]

Good Question, Rohit, it has to do with Subnetting. When Host A was configured, it was given an IP address (11.11.11.10) and a Subnet Mask (255.255.255.0). Through the magic of subnetting, that will tell Host A that they are on a network which contain the IP addresses 11.11.11.0 - 11.11.11.255. Host A was also configured with a Default Gateway (11.11.11.1). This is the address Host A will use anytime in needs to send a packet to an IP address on a foreign network (i.e., anything other than 11.11.11.0 through .255). Host D's address (22.22.22.40) falls outside this range, so Host A knows the packet must be sent to the default gateway (11.11.11.1). This process is explained further in the article series. Check them out: www.practicalnetworking.net/series/packet-traveling/packet-traveling/

[@rohithk011]

Ok Got it ... Thanks .. There is little request. Can you please take any presentation on switchport ? like Trunk port,Access port and Native ports. By theoretically it looks simple but when we try to understand the ingress/egress packets from these types of ports it is really confusing :). It will be so helpful if you explain with same manner.

[@PracticalNetworking]

Hi Rohit. I've written some articles which covers those subjects exactly. Check them out: www.practicalnetworking.net/stand-alone/vlans/ www.practicalnetworking.net/stand-alone/configuring-vlans/ www.practicalnetworking.net/stand-alone/routing-between-vlans/

[@WeGotBellys]

Host A will not randomly just figure out the default gateway itself your answer is incorrect.

Somehow I missed this comment. But you are correct, what I wrote can be misinterpreted to imply the default gateway is "figured out" automatically. I've updated the post to clarify. Thank you for pointing this out.
