Right he really does. I watch a video of this series right before I study and during my practice quizzes.

[@SmittyWerbs2016]

I am a Cyber Fundamentals instructor and I just want to give props to you! Teaching any portion of IT is hard and you do an amazing job of explaining concepts and never going too deep to confuse new learners. Huge fan and will definitely be watching more videos!

[@TAY12101]

I want to learn so much it’s hard to figure where I fit in with technology I like coding and now I’m starting to like networking it’s all exciting but a bit overwhelming and being ADHD I’m all over the place with no real guidance in college I don’t want to just get another degree and not have a career it’s hard to find a mentor or an entry level job

[@andyhunter4850]

I like how excited you are about teaching others, on a career you enjoy. I will never forget watching a speech from Steve Jobs. When he said," you will never work a day in your life if you enjoy what you do for a living". Thank you Chuck, for sharing your knowledge!

[@wambamcamcam]

I love that you cover a lot of stuff that is taught in my class. You present it in a much easier way to understand and your videos have really been helping me out along the way. Taking my CCNA in a few weeks.

From a first year admin who works at a 60+ site company with MPLS, and secondary internet lines, this helps fill in a lot of gaps on understanding why it was done the way it was done. Thanks for the great video!

[@codywatts4399]

Your communication style of teaching is so incredibly helpful to me that I thought I would mention that to you. Thank you for putting out real quality content for people who are sincerely trying to learn and understand. I am sure a lot of work goes into these lessons, so thank you.

[@nhbrid9471]

Please do not stop making these videos!!! You are a awesome teacher. The way you explain everything is very easy to understand. Thank you for making these videos.

[@darylallen2485]

There is more than one classification of WAN. There is public WAN (which includes internet) and there is private WAN (MPLS, SD-WAN, IPsec tunnel, Frame Relay, Dark Fiber). This is a good topic to share because its something I had to learn on the job. None of the educators on networking technologies really explain it at the level that a 5 year old can understand. Great video.

[@davidcterreri85]

I've been in telecom for about 16years and you nailed the concepts in this video. Well done!

[@SuppleInterface]

One thing I loved about this channel is the smoothness of presentation/animation, as well as very clear and concise.

[@rty1955]

I remember working for the nations largest bank and we needed communications for the ATM network around the globe. Leased lines wer mad expensive, so they launched thier own satellite! Problem solved. I worked on the ATM support services which monitored EVERYTHING an ATM can do. All rhe ATMs were in constant communication with my particular system. The ATMs were polled all the time like "are you there?" "Yes im still here. Alive and well" these polls happened at least 1x second. If the ATM failed to respond within that second, it was dropped to a slow poll list (1x every 5 seconds) depending on where the ATM was located if it wasnt heard from in a period of time, an alarm was generated, and a status MSG was sent to the NOC for investigation. Some satellite delay times were 5-7 seconds and timeouts would have to be adjusted. Without giving company secrets away, one key, is very tiny data packets. This made the ATM network one of the most reliable in the world. Oh we designed and built our own ATMs as well

[@classless88]

This is seriously high quality content. Love it.

[@ajjimenez5710]

Hey @NetworkChuck I can't thank you enough for your content. It's brilliant. Engaging, entertaining, and really breaks down these concepts in a way that I can actually digest them. I'm also a father of 3 (all girls!) making the jump to IT from the medical field, and I honestly wouldn't be able to do this without your videos. Thank you and bravo!

I just came across your channel today. I do a lot of network engineering (not to your level) and this is such a fresh change. I enjoy your excitement and energy discussing what for most is a mundane topic. Thoroughly enjoyable! Keep up the great work!

[@tonalddrumpboe5151]

MPLS (multi protocol label swtiching) connects your LAN to your ISPs carrier network. But you share the same lines with other customers. It is private because their your data travels through its own virtual ciruite through the use of labels that keeps your traffic separate form others. Customer edge router Provider edge router E-line (uses Ethernet virtual circuits) connects swtiches between your LAN. E-Lan E-tree: everybody connects to the data center Site to site vpn (goes over the entire internet) adds headers and encryption to packets QoS: quality of service certain traffic is prioritized DIA: dedicated internet access

"Metro" connections are also used to connect two datacenters in the same city or different parts of a city. That allows setting up at least two node (server) metro clusters for high availability services (database, application etc.). Physically it can be ethernet or fibre channel, usually two lines (yes, also for high availability).

Man I wish i found your channel sooner, the way you teach passionately encourages me so much. I hope you never stop

[@jepubepu9570]

I was looking into CCNA and other networking jobs in my country that I might take upon in the future (I'm still in college) but most of them require 1-4 years of experience. Can you maybe give me advice on something to do before i get qualified for these jobs? Im trying to learn job-worthy skills before I graduate

[@FaLkraydz]

Thanks to you chuck now I love network. I’m still preparing to start an IT career as a help desk. But I already want to become a network admin and sooner than later break into cybersecurity. This is the path I see as the best one. Thanks for all you work and content.

[@michaelcarey]

I've set up a wireless WAN to connect my home to my workshop (around 3.8 km away). I don't have line of sight so I have set up some 5.8 GHz gear at a comms site I have access to. I also have some amateur radio equipment at the comms site (MarineTraffic AIS receiver and FlightRadar24 receiver). It's nice to be able to access network resources at home (including the internet) when I am at my workshop... it's just like having a long (but slower) Ethernet cable between the two locations. Love my WAN!

[@zaidiatifs]

I have been a wireless guy and want to switch my career and want learn wan .. i saw this video and u totally nailed it

[@lelandclayton5462]

From what I have seen in the wild is the Corp office and Data Center will use a MPLS and all of their "coffee shops" will just be connected to the Web with Static Addresses so a Tier1 or Tier2 Tech can remote in for troubleshooting and such. Included in the MPLS will be a Call Center and possibly a Managed IT Support firm. All depends on the type of company it is. I use to see AT&T would bring in two Fiber Lines for the location then use a T1 connection manage the Fiber Connection, ATT hates sending out their Techs.

[@Darkk6969]

You are 100% correct on the key points you presented in the video. SD-WAN is still an uncharted territory for most network admins. They have heard of it but afraid to make use of it despite how easy it is to implement. So maybe a future video on how to make use of SD-WAN.

[@evankirschenmann4653]

Love the CCNA content. This has been some of the most useful, informative content I've ever found on KZbin.

You know Chuck got really excited explaining something when he throws away his pen. Awesome video Chuck, I've been learning a lot from you lately. Thank you :)

[@Konvinced89]

I just got really excited because I picked the last three, and was only able to half-listen to most of the video. The analytical breakdown of the question makes a lot of sense to me. I need to rewatch and get more of the meat, but knowing I would already get even this one question right is encouraging.

[@zipp4everyone263]

Well, as a consumer, thats all you need to know. Its not like conmsumers are allowed to know the exact config of their lines nor are they expected to know the difference :) Working for a fiber ISP i've come to understand that what most people think they know is that more Mb/s = stronger wifi reach... Dont worry =P

[@G4rg0yl3z]

I remember having a "Metro E" connection between my company and the datacenter, but they where in different cities 120 km apart. We rented dark fiber com the railway company, and literally stretched a fiber cable from the office to the train station (+/- 1km) connected it to their fiber patch panel, and they some fibers allocated to the same datacenter we where using, se we had "the other end" on our dedicated Rack.

Great videos, not going to be a network engineer but as a programmer helps to get a deeper understanding of networks other than thinking of them as a "dumb pipe".

[@leswaggoner931]

NetworkChuck, just wanted to say kudos for breaking down the information into nice bite sized chunks and making it deliciously edible. Being a self-taught technician with no formal training, and I have run into about 80% of the networking scenarios you speak of as I meandered throughout my career. Having made the decision to start looking into getting a CCNA and other Cisco certifications, I ran across your youtube videos. Excellent information in a fun and informative manner. Again, kudos to you, for making this information fun again.

[@lelandclayton5462]

You honestly don't want to know. It's a jungle and I am surprised a ISP or WISP know what they are doing.

[@camplays487]

Speed for the most part. since capacity is only limited by our ability to put up more satellites and generate information.

[@mohammadfoadtavakoli7118]

I am talking about when we buy internet for our sim card

[@misaalanshori]

@@mohammadfoadtavakoli7118 You are paying your isp to use their services and infrastructure. When you "buy" data for your sim card, they give you access to the internet via their infrastructure. So technically you're not paying for any physical thing, just paying for permission and access to use their service to access the internet.

[@trustmyhacks]

@@mohammadfoadtavakoli7118 you are basically buying a ticket to access infrastructure its like paying to use high-speed highways

I have heard of WAN being used for connecting networks of different sites but it's usually only practical if they are somewhat close distance wise. If the sites are too far to run direct lines then they will use Internet as the medium for communication.

[@ithereos9554]

This was one of the key points I had issues understanding, because no entry-level networking book (not even Cisco's) is kind enough to put in clear words that the WAN is not necessarily the Internet (although the Internet is a kind of WAN). Just a thing... I am not sure SD-WAN is supposed to replace MPLS. All SD-WAN can do is make the network more... smart, let's say, but SD-WAN is built on top and depends on the underlying technology (Internet or MPLS, for example). You can use SD-WAN over Internet all you want, and you can have encryption building all those VPN's between your sites; but your super smart tunnels are still on top of the messy, lossy, wild Internet. Most customers I work with continue to have an MPLS link and an Internet link and they use SD-WAN over both of them, so if you could clarify why you believe SD-WAN is an alternative to MPLS, please let me know. Love your videos man.

You can't get ATM or frame relay from many telco providers any more. CenturyLink will only support existing circuits, you can't order new. What everyone is doing now is either leasing you a pair of dark (unused fiber) or a PON.
