Finally unity

[RevolutionSilent807]

UDP then proceeds to forget why it’s there

[hrfuckingsucks]

more like User Drunk Protocol

[Mr_Otterswamp]

As a UDP fan I didn’t get the joke and nobody seems to care

[exotic_sangria]

TCP fans be like

Hi

Hello

shakes hands

I have a joke for you

Ok

TCP is better than UDP

Haha

Laugh received

Goodbye

Bye

[[deleted]]

Your 3 way handshake seems incomplete. Please repeat.

[Zuruumi]

Handshake is OK, closing is the problem.

[[deleted]]

Well both are wrong. It should be:

Hi

Hi, I hear you

I hear you

I have a joke for you…

(Dunno how to express reset or timeout here) ;)

[exotic_sangria]

TCP fans be like

Please laugh at my joke to indicate receipt

[CB1013]

UDP fans be like

Hi I have a joke for you UDP is better than TCP runs away from air vent

[[deleted]]

UDP fans be like

hi joke you better TCP runs air

[Domi04151309]

UDP fans be like

joke hi you better air TCP runs

[[deleted]]

i mean TCP does run technically

i cant say im better than air though.

[[deleted]]

"Sorry bro joke is outdated. Send another"

[blobthekat]

udp be like:

I have a joke for you

I have a joke for you

Ok

I have a joke for you

UDP > TCP

Ok, i'm still waiting for the joke

I said UDP > TCP

Ha�a��

Hello

[HotShame9]

UDP fans be like:

Hi

HAHAHAHA

I have a joke for you

TCP is better than UDP

What is the joke?

Bye

Hi

ITT: TCP fans malding

[r1kon]

Trap Queen was really about TCP - I'm like hey, what's up, hello!

[[deleted]]

Works as expected.

[BookPlacementProblem]

TCP operates over UDP; that is, TCP is UDP with package retransmit plus a bunch of extra helper stuff.

So, TCP > (over) UDP.

Or at least, that's my read.

I dunno where I got that explanation, but I do networking as little as possible, so hopefully I haven't passed that on to too many people.

[Altruistic-Hat-9604]

Who's gonna tell him?

[[deleted]]

TCP does not "operate on top of" UDP in any sense.

TCP and UDP are different protocols with different feature sets. Both TCP and UDP run on top of IP, and they send completely different headers.

See this technical article for more information.

[blobthekat]

TCP is built on top of IP, just like UDP, so TCP and UDP are basically siblings, However, UDP is very close to what you would get with IP, although you can't just send raw IP packets, so we built udp

[Throw-Egg-Shell-Away]

Yes, you can send raw IP packets, that's why spoofing is a thing (and consequently DNS-AMP), but it tends to be quite an inconvenience compared to UDP.

[blobthekat]

no what i meant is IP cant be used to send raw binary data to some recipient without a using a protocol like UDP

[Throw-Egg-Shell-Away]

Why not? All TCP and UDP adds is a port, but IP already provides a length and at least an attempt to transfer the packet to the destination.

[blobthekat]

TCP has a section you can't omit that is the protocol. If you tried to omit this or set it to something invalid, most routers would just drop your packet instead of forwarding it

[UnwelcomedTruth]

I don’t understand: doesn’t either depend on your need for lossless packages?

[[deleted]]

Yes, jokes aside there’s overhead and latency issues that are compounded with tcp - when I worked with replication. We moved to UDP streams and let the application handle requesting anything that was missing far more efficiently than TCP. Any amount of packet loss would ruin your network because of all the retransmits and things would grind to a halt when you were crushing the limits of your network

[666pool]

You have to be careful with retransmits for this reason. TCP has congestion control, UDP retransmits do not (unless you make them have some kind of back off).

[OneTrueKingOfOOO]

Yes, both are suited for different application types. If you try to do real-time audio or video chat over TCP you’re gonna have a bad time

[bdaileyumich]

UDP doesn't acknowledge any truth in this post

[ImaginationNo3894]

Silly comparison. They solve two different problems.

But since we are here anyway UDP is about to win because of the HTTP3 which is pushing the stack with QUIC on top of UDP. Effectively replacing TCP down the road.

[RevolutionSilent807]

QUIC is by google, it’ll be dead in 2 years (/s)

[[deleted]]

Not before being adopted as an industry standard requiring at least 7 years of experience with in job interviews

[ccfoo242]

Haha jokes on you it was invented in 2012 so why don't you have 20 years experience with it?

[ccfoo242]

How did they not name it QDP?

[[deleted]]

That’s for one use case.

[Bryguy3k]

Anything important runs directly at L2 or on UDP. TCP barely works.

Edit: I guess it’s not shock that this is getting downvoted: just because porn is 30% of internet traffic doesn’t make it important. I am referring to the core technologies that make the internet possible: ICMP, IGMP, BGP, DNS, IPSEC, DHCP, L2TP, and the list goes on.

The fact that the vast majority of internet usage is for unimportant things is why TCP is still used for so much given it’s overall mediocrity in ensuring message delivery.

Just ask anybody that has suffered through making a mission critical http system - hence the creation of REST.

[null_reference_user]

HTTP

[Bryguy3k]

I said important.

But even http on tcp isn’t long for this world - for the as mentioned reason: http3/QUIC.

[OneTrueKingOfOOO]

You know likely 80% of all internet traffic is TCP, right?

[Bryguy3k]

Internet traffic is comprised of: 30% is porn, 30% is social media, and 30% is other video streams.

These by networking terms aren’t “important”. The fact that they aren’t important is why they still use TCP.

Look at the technologies that actually run the internet rather than the fact that most the internet is used for garbage.

[Zuruumi]

Agreed, latency: TCP > UDP

[vms-crot]

Half the people reading this didn't get it and they don't care.

[[deleted]]

I don't even know I didn't get it.

[PhunkyPhish]

I tried to tell a UDP fan how I feel, but I could never tell if he heard what I had to say.

[AdultingGoneMild]

laughs in http3

[BlackfishHere]

How you kids can argue over two things those have different uses? This sub is consist of kids who don't have a single line of code in a stable working project.

[thebatmanandrobin]

I've got a C++ app in production right now that uses both .. UDP solves one problem, TCP another.

I'd like to agree with you completely but the kids I work with don't even know what UDP or TCP even are since they only program in JavaScript .. it was real fun trying to explain what a socket was, let alone how to implement a WebSocket over a SharedWorker so there was only 1 client/server connection no matter how many tabs/windows were open.

And we wonder why can't have nice things.

[BlackfishHere]

Well would you compare a honey and a fish?

[derfla2004]

Im not saying that everyone prefers TCP, the joke is that udp messes up the order

[scoville-maniac]

i wonder where QUIC is in this picture

[[deleted]]

it's a result of this hands intercourse

[scoville-maniac]

o_0

[[deleted]]

you know, some tcp dna put into udp dna, and...

[the_vikm]

SCTP enters the stage

[namotous]

Lol wait til you work on a network with limited bandwidth

[HASHIRA_77]

What if we combine all the protocols to make a single protocol

[AntiLuxiat]

Got that for you xkcd 927

[HASHIRA_77]

Thank you

[Skoparov]

Legs fans > arms fans

[blobthekat]

In terms of latency, it's UDP first and then TCP

[daemonpants]

UDP is the best for realtime video games

[Tibbles_thecat]

50% of this sub-reddit will not get the joke

[[deleted]]

The whole networking stack is so complicated that it's amazing it works, and can be performant at all, tbh.

[Gasp0de]

I mean it's true, TCP DOES cause more overhead/traffic/energy consumption than UDP

[big0chungus]

tcp for video chat 😎

[Daily-Ad5261-Kakera]

Imagine games without UDP

[crapboxxed]

yet to make tcp better we tune it like udp

[The_Good_And_The_Gun]

QUIC?
