Strap 20 sd card with 1TB capacity each. Send the pidgeon to a neighboring city, 2 hours flight time.

Bandwidth: 2.78 GB/s (assuming no wild hawks in the area)

When "packet loss" occurs:

You are forgetting the time it takes to copy the data to and from these cards. Data may be transported, but it is not usable until you copy it. Copying 20 TiB is probaply going to take some time

[–] redcalcium@lemmy.institute 7 points 10 months ago (1 children)

Fastest SD card has ~300MB/s read speed and ~250MB/s write speed. Assuming you can write to those cards in parallel, that means you'll need an additional one hour to write the data to the SD cards and another one hour to read them back. So 4 hours in total which halves the data rates to 1.39 GB/s.

That's assuming the card can actually sustain ~250MB/s write speed during the full 1TB copy. It probably can if the card is freshly formatted but I haven't actually tested it myself.

[–] BlueMagma@sh.itjust.works 2 points 10 months ago

That's still very fast

[–] tryptaminev@feddit.de 5 points 10 months ago

you have the same problem with downloads though. In the end any download rate exceeding your disc write speed doesnt get you there faster.

ofc. you can write as you download, which makes things faster.

[–] Pipoca@lemmy.world 2 points 10 months ago

MicroSD cards are better, here. They're 250mg; a pigeon can transport 75g. That's 300 microSD cards, ignoring the weight of the SD card enclosure.

When Baldur's Gate 3 came out our group of friends wanted to start a game together. Since one of our friends, living about a kilometer away, has shitty internet it was faster for me to download the game myself, copy it to a USB stick, have it driven over by another friend, copy it onto the friends PC and verify file integrity than downloading it.

German internet in a nutshell.

So yeah, IPoAC would've it's purpose.

For render the first picture of a black hole a couple of uear ago, the data transfer was done through hdds transported by a plane, than a data transfer through Internet, because the former was so much faster.

It's a real quote, from the 80s, published in a networking textbook.

It's amusing, but it's always been a serious and occasionally practical observation.

Is it a German reaction to think: Hey, 50MBit is not that bad?

[–] Zunon@lemmy.world 2 points 10 months ago

I still remember when 150KiB/s was what we had as a child. It was very usable for the small amounts of data we needed back then.

[–] Zunon@lemmy.world 5 points 10 months ago

Seeing it written as MBit/s feels so wrong to me, I read it as MB/s at first then I realized it's Mb/s.

[–] stingpie@lemmy.world 5 points 10 months ago (1 children)

I'm assuming English isn't your first language, but "IPoAC would've it's purpose" is grammatically awkward. "Would've" doesn't really work for possession. Instead you can use "would have," but people would typically say "IPoAC has it's purpose"

[–] Senseless@feddit.de 3 points 10 months ago (1 children)

Thanks for the clarification. You're right, English isn't my first language.

I'm a bit confused by your sentence:

""Would've" me doesn't really work fur possession. Instead you can use "would have""

That's the same thing, isn't it? My idea with using "would've" was that IPoAC would have it's purpose, if it was a thing. I'm missing the descriptive word in either language right now.

[–] stingpie@lemmy.world 6 points 10 months ago

The word "have" is used in two different ways. One way is to own or hold something, so if I'm holding a pencil, I have it. But another way is as a way so signal different tenses (as in grammatical tense) so you can say "I shouldn't have done it" or "they have tried it before." The contraction "'ve" is only used for tense, but not to own something. So, the phrase "they've it" is grammatically incorrect.

[–] Pipoca@lemmy.world 5 points 10 months ago (2 children)

IPoAC is a joke about printing actual IP packets, sending them by pigeon, then scanning them.

You do the whole usual TCP ACK/SYN thing, but with pigeons.

It's not the same as 'sneakernet, but strapping microsd cards to a pigeon'. It's way, way sillier.

But also super high throughput.

[–] Aceticon@lemmy.world 26 points 10 months ago (3 children)

The protocol is highly susceptible to DOS attacks by means of BB guns, slingshots or, for more sophisticated hackers, trained hawks.

[–] wizzor@sopuli.xyz 13 points 10 months ago

"Unintentional encapsulation in hawks has been known to occur, with decapsulation being messy and the packets mangled."

[–] uis@lemmy.world 2 points 10 months ago

Or more sophisticated hawks

[–] itslilith@lemmy.blahaj.zone 2 points 10 months ago

more sophisticated hawkers, if you will

[–] onevia@lemmy.blahaj.zone 25 points 10 months ago (1 children)

"an example of packet loss" 🤣

[–] threelonmusketeers@sh.itjust.works 10 points 10 months ago

Yes, we also saw the same post you did.

[–] ExLisper@linux.community 24 points 10 months ago (1 children)

Some guys actually managed to do a ping using this standard. I saw pictures and all.

Please note that IPoAC may suffer fatal device failure when delivering HTTP 418 error codes due to packet overheating.

[–] Treczoks@lemm.ee 20 points 10 months ago

Ahh, the good old RFCs dated April, 1st. This one is number 1149 ( A Standard for the Transmission of IP Datagrams on Avian Carriers), and got later updated in RFC 2549 (IP over Avian Carriers with Quality of Service).

[–] TheFriendlyArtificer@beehaw.org 19 points 10 months ago

So Alfred Hitchcock predicted DDOS attacks decades before they were a thing?

[–] zurohki@aussie.zone 18 points 10 months ago (1 children)

Old news, it's been superseded by RFC6214.

Routing information protocol, little pigeon, routing information protocol.

[–] kamen@lemmy.world 11 points 10 months ago

Imagine playing a shooter over a network using this protocol.

[–] EtzBetz@feddit.de 11 points 10 months ago (1 children)

You need to set a pretty damn high timeout time for this to work.

[–] Malgas@beehaw.org 9 points 10 months ago

That said, the bandwidth of strapping microSD cards to carrier pigeons is actually pretty high.

[–] keepcarrot@hexbear.net 9 points 10 months ago (1 children)

Reminds be of the conversations about transferring hard drives using the public transport system in my city. Good bandwidth, terrible latency. Then everyone got faster internet and stopped pirating

My neighbor bought a bird feeder, how do I defend against MitM?

[–] UnverifiedAPK@lemmy.ml 4 points 10 months ago

Buy better seed and a bird bath.

[–] hakunawazo@lemmy.world 4 points 10 months ago

So it's obviously not a sneakernet. Is it a wingnet?
