Internet Infrastructure as Fast As Possible

What is actually happening to data as it travels through the internet? Does it get passed around through a series of tubes? (Hint: it doesn't)

[@CoWinkKeyDinkInc]

I actually thought it was an ad at 2:50

[@XLucifersX]

CoWinkKeyDinkInc whats the name of the cartoon in your avatar :D ?

[@05predo]

CoWinkKeyDinkInc just at that moment, i came down here hoping that i wasnt the only one. THANKS INTERNET

[@xMrin10se]

When is it never an ad

[@PTNLemay]

CoWinkKeyDinkInc lol, same. I was just about to say "You almost did it Linus! You almost made a video that's 50% ads!"

[@airplanetony]

CoWinkKeyDinkInc I didn't even realize it was not an ad until I starting scrolling down and read your comment

[@JuanMorales-bv7qr]

linus says "and speaking of", and doesn't mention an ad... my perception of reality... shatters around me...

[@ng3027]

2:49 for the moment I thought he was going to do a segway to his sponsor

[@vincenthodges647]

ikr lol

[@kveeder3224]

That would be one long ad!🤣

[@qwertopchicken]

2:20 ahh linus. that's why we love you XD

[@D3thr3lic]

[@2D2sChannel]

Does anyone know, what happend to episode 7 yesterday? Wasn't it aired an TV or just the internet not working anymore?

[@tbon88]

2:24 that squee always makes me chuckle.

[@ElectrifiedBacon]

I know that feel, bro.

[@darksunrise957]

***** ikr! That also implies that someone there knows the show enough to identify and use that iconic sound clip! :)

[@HaxxorElite]

Jordi Santini wtf u gay?

[@JoeHabana]

Isac Degmez dude, what does being gay have to do with anything he said? i`ll tell you, *nothing*

[@HaxxorElite]

Joe Habana *something

[@jonesnj07]

you just taught me more in 3 minutes than my cisco teacher did in 2 years...

[@armybear2]

Nathan Jones Funny thing is he didn't really explain anything of value other than the DNS server factor.

[@slimeball6408]

Me too

[@SanyaIVLitvyak]

Nathan Jones Your Cisco teacher must have been quite terrible, or you simply didn't pay attention. Linus didn't even mention routing protocols or anything similar, which is something you should have learned by your Cisco teacher along with quite a lot of other things.

[@jonesnj07]

Sanya IV Litvyak he was awful and was only ever a willing to help the 2 girls, we only did virtualisation through a programme called packet tracer even though he had a shit ton of equipment, once he left we started using the hardware and made our own Cisco class.

[@mintymilkk]

Nathan Jones Have you ever considered that some things might not be other people's fault?

[@GlenwingThink]

Internet infrastructure is definitely not as fast as possible >.>

[@Grymyrk]

GlenwingKyros Sure it is but it's only as fast as the slowest node in the route. Which is probably the ISP that likes to throttle the connections.

[@Guldaar]

Grymyrk True in theory, wrong in practice. Speeds given are often arbitrary and artificially policed to a low rate, yes that is a real inter-networking term. Case an point, Google Fibre moving into certain cities in the states and miraculously speeds offered by competitors are up to 6x faster for the same price OVERNIGHT. And yes, I work in the industry, I'm not just blowing smoke.

[@Grymyrk]

Saelaniify I have a Bachelors Degree in Computer Science majoring in Computer Networking. So there. I don't disagree with what you say but I already said it.

[@Guldaar]

Grymyrk You didn't tho, you made more of a blanket statement while while true in theory, just isn't the issue is in the real world.

[@Grymyrk]

Saelaniify I said some service providers like to throttle. You said some ISPs stop throttling when there is competition. How is that incompatible?

[@MattsMotorz]

2:24 I love the little squeak noise that played for the my little pony packets. LOL

[@Medic26898]

It's known as a squee.

[@EonityLuna]

kzbin.info/www/bejne/kHOwdWmZZ7d3qck

[@swmike]

I would have appreciated a mention of the IETF (Internet Engineering Task Force) which has a lot more to do with Internet infrastructure than ICANN does. That's where standards for IP, TCP, UDP, HTTP, SMTP and all the rest are created and maintained.

[@terryperehinec]

Hey Linus, I really enjoyed the video. I've been watching all your videos and gotta say, there great! this one especially just now because I've been studying CCNA and it helped answer some stuff I've been stuck with. Keep up the great work!

[@jmwloup5110]

Linus I love your videos and I applaud your pride of Canada. Sadly you're slightly mistaken. You talked about ICANN running the internet but because you are not employed by the US Federal government, as I am, you may not know that ICANN is controlled by the US Dept of Commerce. This is done through ICANN's administrator NTIA, a section of this federal department. Now to be fair for over a decade their has been an international push for IANA, which controls IP addresses, to fall into international hands. The opposition for this is that many concepts that led to today's internet came from the US such as NSFnet. This is a US science foundation for advancing education to higher learning institutions. Predateing that is ARPAnet, a US military agency for federal projects. It should be no surprise that the internet has been largely controlled by the US and maybe even rightly so.

[@NeoChromer]

College 2nd year killed me with these packets and theory RIP protocols and other stuff which i forgot.

[@tacoburger5]

that shirt is giving me OCD

[@ramshambo2001]

I know! GAAAAH!!!

[@Oahnay14]

tacoburger5 haha, I did not even notice it until you said so. that is funny!

[@OnionMF]

tacoburger5 Didn't you know he has an invisible second head. The only way to cope with OCD is to get creative.

[@soda_gt.]

i cant watch the video properly because of his shirt

[@TheLlamaFarmer3]

tacoburger5 I'm pretty sure you don't know what OCD is.

[@SeeonX]

Howdy! Long time fan! I'm sad to see you didn't cover prime time ISP bog down for the US which is a major issue still for some places or the fact traffic isn't always rerouted when everyone in an area is streaming netflix(as am example). This is a major issue for us in the US. I would like to see this information covered in the future or more insight on why the route isn't always redirected when an ISP or ISP peering partner like Level1 or tcore nodes is dropping packets or having issues. Thank you! Keep up the great work! You guys are amazing!

[@nexorabolis]

Love techquickies. Seriously learn so much haha

[@TacticalWolfxQC]

2:20 OMG THANKS LINUS!!!!!!!!!!!!!!!!!!!!!!!!!!

[@mdukasa]

Slim Dashie might just be the 5th of the pony fans. weird

[@cyanmoonlight7147]

*squee*

[@VisualBasic6]

Woot ! Woot ! made it into a Fast as Possible video :D :D :D best day ever !!!

[@M4TTYN]

givingtnt lol haha kind of jelly oddly xD

[@doctorpc1531]

givingtnt wait, could you send me a time link? (ie. 1:00)

[@VisualBasic6]

DoctorPC pelailut @0:05 im the second tweet

[@doctorpc1531]

givingtnt wow... didn't notice that :D Congrats, buddy!

[@autoperson1003]

givingtnt Jealous...

[@EricBaileyDrums]

I would love to see a follow up video about the hardware infrastructure of the internet, too.

[@Nika_Scott]

This is easily my fav channel on youtube.

[@greenday9090]

When you said "Speaking of jumbled messes..." at 2:48 I thought you were going into the ad.

[@bloody_pinata]

Literally had my networking exam 4 days ago. Would have been amazing to watch this before that. Extremely consise

[@BorkBorkDoggo]

MLP in an As Fast As Possible video, my life is now complete!!!

[@hrtbrkd]

Next Tech Quickie. Explain the OSI model. Great stuff btw. The way I see how stuff get routed/switched. -> (Layer 1)10101010 [Binary] [ethernet protocol] -> (Layer 2) Binary encapsulated into a frame [Switches] -> (Layer 3) Frames encapsulated into a packet either ipv4 or ipv6 depending on the application -> (Layer 4) the sending method is decided uses either TCP or UDP for reliability or unreliable traffic.-> [now the packet is routable by a layer 3 switch or wan router using eigrp/ospf/ripv2/or a static route] Then the packet is sent to the ISP who uses either BGP or ISIS routing protocols over an MPLS network (hopefully). As a network engineer we normally don't care about Layer 5,6,or 7 but some times I have to troubleshoot those >.

[@AdrienKennebec]

I loled at the fart noise and the toilet flushing when he started talking about people putting stuff on the internet

[@PvcomputersNz]

Great video, Very informative and good refresher for me.

[@BolttheSuperPony]

2:24 & 2:30 Dat *squee* tho! I love the reference and the shoutout! :D

[@breakinggalaxy6857]

great video keep it up and despite not beeing my favorite chanel i watch and watched every single video

[@J4deyHD]

That packeting image was part of my presentation for computer science when we researched gateways and networking :D

[@wck]

Alright Linus, you got me. I now fully subscribe to Nature's Harmonic Time Cube Principle.

[@rrr14785]

Would be nice to have updated videos of these

[@0Keyboard0Eric1]

If we refer to the term "internet" as interconnected networks, the video applies well as an explanation. But the mention of the HTTP protocol was somewhat unnecessary and could have been replaced to define TCP / IP, Internet socket, or the differences between TCP and UDP, in a simple way of course. Also, *squee*!!! Waiting to see another good video

[@clonetrooper-kv5rk]

Fast As Possible as Fast As Possible

[@avgoustos1]

as fast as possible: how can you program a programing language (how to give life to a machine in the first place)

[@praf2]

it would have been awesome if they would have covered a little the physical infrastructure of the internet as well. :D Say more about how the data actually/physically moves around the globe. Does all the internet rely on cables or do some companies provide internet using satelites?

[@KutsukiTsukiyo]

Why the fuck do people dislike it before they're even done watching the video?

[@zafarrancho9555]

Alexis Wynter Because they didn't like the subject?

[@forlexer]

Alexis Wynter miss click

[@zxcvbnm2992]

Alexis Wynter have a bigger problem with people liking it before they are done watching

[@FalyHero]

Trolls.

[@xxDrain]

***** Giving a dislike on youtube is not trolling, you ignorant, part of the problem fuck.

[@GreyDnB]

I like how people react that that mlp joke, thinking its so innocent (and it is) but if it was made on some other, smaller channel, that video would get so much hate

[@KayTang0822]

your videos are like lectures, but not boring at all and I acutally learned stuff. XD

[@grantkidd4142]

Could you please do more Networking TechQuickie videos!

[@Outfrost]

"(...) here, wherever it is you're watching it." *takes a look around the bathroom

[@MadSupra354]

I think it's about time you made a ping jitter FAP.

[@CallanElliott]

The analogy to the sewer system is more apt than many would realise...

[@nuIlIllI]

Best explanation ever I saw

[@locoperson11]

Linus finally understands ponies and their importance.

[@locoperson11]

Tortilla Flipper Will do.

[@HaxxorElite]

To Athanatos stop talking to yourself

[@Lambda_Ovine]

Isac Degmez Oh no, I was talking to YOURself!

[@HaxxorElite]

To Athanatos no no no

[@tommytomthms5]

locoperson Elf Wow you are all the same person... how sad...

[@stratta_yt]

I learnt something today Thank you

[@CadetRedShirt]

that perfectly timed squee

[@henkpoa]

I work at a NOC in one of the world's largest IP networks, and I can safely say that congestion is normally not "dynamically" avoided. Though there are ways to go about it of course. There are ways to avoid congestions though, mostly through network and traffic engineering.

[@CoolSs]

1:01 I was just looking to understand the subject more . glad you made that pun ;p I am from there .

[@SRMsuperrandommoments]

How did I already know this? Old techquikie?

[@OneNot]

"it's just like, beep beep boop" Oh Linus, you're so good with words!

[@42thgamer80]

Great video!

[@nightskyft]

Ah, an oldy, but a goodie!

[@SleeveBlade]

2:49 "speaking of ...", almost quit too early there :p

[@M4TTYN]

Interesting and learn a lil bit with the great Techquickie channel :3

[@thisguy153]

YO Linus, thanks for the Ottawa shoutout!

[@davidw2319]

0:00 This example has aged very well and will probably age even better.

[@matsgd]

2:43, I thought my pc was slowly dying, I peed my pants

[@turboshamu]

linus may i ask you make a video about the difference between air flow fan and static pressure fan please

[@pinkie87]

Maybe some explanations about FinFET? It will become more and more interessting in the near future^^ And big thumb up for the "Squee" :3

[@nizamersoft]

"WTF are you talking about?" lol

[@959293A]

You didn't explain about TCP/IP or the OSI model could you do a explanation on that as well. Thanks

[@jay4351]

Kurz gesagt made a video about this recently and explains it alot simpler

[@ashindnile]

In fact there's Paragon NTFS for OSX that works out for reading and writing to all types of external hard disks.. Even without it installed if I connect my hdd to my modem(setting up a SAMBA server) I can r/w to the disk using osx.

[@crzykd1305]

little add on note, depending on the protocol your using to send the data it may not arrive at all. there arr 3 common protocols, TCP - packets are guaranteed to arrive and can only be accessed if the preceding packets have arrived, this is good for file transfer, no corruption, no disordering UDP - packets are not guaranteed to arrive, BUT packets can be accessed as soon as they arrive regardless of order, this is good for things like skype and games where only the most recent information is important HTTP - this is the protocol used by your web browser and for the most part is and extension of TCP, it has certain rules in place to communicate with webservers which aren't needed in most TCP connections outside of HTTP.

[@Yemto]

Scott Howell What about FTP?

[@crzykd1305]

Yemto if you'll include that in common ( I suppose it is quite common actually) FTP is quite similar to HTTP, its built on top of TCP, its basically TCP with some username and password stuff lumped on top, not that much interesting about ti, I usually just consider it TCP.

[@oregonfishing1116]

2022 here figuring it out more

[@Edd360]

the internet is not a big truck that you just dump something on, it's a series of tubes

[@scipio8303]

Loved the MLP reference. But who's a brony at linus teck tips ?

[@bitMasque]

2:50 "Speaking of jumbled messes... Lynda.com!"

[@dc2008242]

0:12 I actually pay attention to the mechanical processes of my toilet.... it tends to clog or not flush every now and then and I have to know about everything technological (which is why I'm here)

[@xiNerdLordix]

2:20 I love you Linus

[@will3346]

So I have 2 questions how would a new ISP start up and not piggyback off of a bigger company and if everything was connected wouldn't the speed of the Internet not only depend on me but on the server that's hosting the website

[@BanditoPlays]

Interesting video man

[@burtonh1]

Let's you someone was planning to move to a new city. How could the find the connection tower (or whatever it is called) to where they plan to live?

[@brownruns]

2:50 I thought that that was the sponsor spot :,D

[@ManIkWeet]

2:00 yay Lnik in the description.

[@sjaakcornelis9960]

Never saw 4k, So smoooth!

[@rayden54]

I thought this would be about the physical infrastructure-like the fiber optic cable that runs through my back yard.

[@theBuZzEr1811]

can you explain the difference between the new hdd-s, green, blue, I know the basic differences of the old ones but today they all seem to be the same, samo rpm, same 6 gb/s sata 3, same cache. Google only shows me old results from 5400 rpm drives.

[@bluephreakr]

When he was talking about Mac and PC I thought he was going right into sponsors and plugging Dropbox. It sounds like something he'd do.

[@mrballbreeder3749]

explaination was very basic but the basics was well explained. the internet is region networks that is connected to each other with connection servers. would be even an shorter explaination.

[@powergamer113]

1:16 "linustechtips.com malware" Hahaha!

[@blinkwin]

but how does packet loss works, if 2% of your packets do not reach destination in time, they are lost and not received by the destination I.P. are then resend by the source or they are lost forever, and if a destination IP received 98% packets does it interprests the unreached 2% or waits for them ?

[@HibHab69]

1:12 ...but when I put in that exact same internet url it took me RIGHT TO YOUR HOMEPAGE :L I sense an elaborate ruse to get me to try to up traffic haha

[@hitchunited1]

I like how a search suggestion was 'linustechtips malware' lol

[@mustafacandan9831]

Please make "what is subnet mask"

[@SatyajitGhana7]

3:27 NO!

[@ParadoxdesignsOrg]

sounds like the internet is the basis of teleportation?

[@hroland]

1:57 Great! The LNIK is in the description :P

[@WillPark98]

Could you do a fast as possible on pci latency timing and the best settings for that in the bios for gaming

[@TheWorkingRobot]

8.8.4.4 isn't google.com ip it's google dns backup server

[@sharks445]

Finally someone who notices

[@majarcool1]

I only have one question what about on our phone or other hand held devices when we browse the internet we receive other forms of the site y can't phones or other handheld devices show the same exact page is it like another computer language or is it the same just formatted differently and I just wasted me time writing this comment? plz anyone u actually knows, answer me that I'm truly curious and I'm trying to learn as much as I can about computers and other things to computers

[@tannerhornung]

“When you send out a tweet about a new graphics card you can’t afford” 2021: nice foreshadowing there Linus!

[@RedstonePro73]

At 1:13 if you stop it at the right time, look at what shows up by the time he types li xD

[@joshi5507]

My teacher said that the internet is basically a HUGE LAN chain. If that'a the case, then how do proxies work? The point of a proxy is to mask your IP or add another layer of security or whatever but wouldn't you basically habe to take the same path to get to the proxy anyway?(Yes I watched the linus video on Proxies).

[@subpanda101]

I swear Linus made a fullmetal alchemist brotherhood reference. Breaking down and reconstructing won't make much sense for human arms

[@dzteify]

What is the brand of shirt that linus is wearing?

[@2feet1up]

Why can't my mail be as efficient as the internet, they're always sending me Barrack Obama's mail.

[@NightmareNyxSparkle]

I love it how this comment section isn't a total mess. It does say something about the majority of Linus's fans.

[@calvinmead7564]

Having to explain how to turn a computer on to your grand parents 0:00
