I get that this is aimed at major backhauls, I'm just frustrated that for the next 10 years we'll be talking about greater and greater bandwidth and not lesser latency. Consumer internet is going to suck for a long time.
- throw_nbvc1234 3y agoTheoretically, space based networking can be lower latency then ground based (above a minimum distance) because of the differences in the speed of light in the two mediums. https://people.eecs.berkeley.edu/~sylvia/cs268-2019/papers/starlink.pdf https://people.eecs.berkeley.edu/~sylvia/cs268-2019/papers/s...
- amelius 3y agoWe could have neutrino based internet where the signal really takes the shortest path, i.e. through Earth's mantle/core.
- arunkant 3y agoIf you can detect them, sure
- bombolo 3y agoIt's perfect for my /dev/zero as a service!

- senttoschool 3y agoSounds amazing. Imagine small, inexpensive, reliable Neutrino detectors. No more bad signals on your cell phone. Reduced latency between long distance communication. No cables needed.
- empyrrhicist 3y agoForget the consumer tech, high resolution neutrino astronomy would be dope. Not that I expect anything like that in our lifetimes.
- vlovich123 3y agoSure you’d get cheap detectors but then you’d be dealing with a flood of artificial neutrinos that blinds our ability to do good research on it.
- Gustomaximus 3y agoAlso something I haven't seen discussed yet is space servers. This has to be a great speed opportunity to orbit some server system a few hundred km above the internet sats and laser link to those rather than retrieve data back from earth.
- vlovich123 3y agoYou have to have enough long distance transmissions to make it worth it. I’m not sure that happens in practice. In other words, even if it were better, the existing status quo is good enough and has a fine price point. Earth based servers are still relatively expensive and need enough physical maintenance on a regular basis. Doing that in space becomes impossible ignoring the fact that you also have a massive cooling problem since space is one big insulator.
- dabluecaboose 3y agoGiven how much trouble thermals already are for Earth-based datacenters, I can't see that being economically viable for a LONG time
- biomcgary 3y agoThe edgiest hackers use Spaceflare (TM) workers at the edge of space, not just the edge of the network.
- _joel 3y agoWasn't 5G supposed to solve latency issues? (n.b. not a 5G user)
- aziaziazi 3y agoYeah, marketers loves to say that because there is a latency gain for the wireless part of the request travel. The more the information you request is close to the antenna, the more you’ll benefit of this improvement. However in real (actual) condition a request travel hundreds or thousands of kilometers through many nodes, each one adding up a bit of latency. So in the end you may feel a difference if you use VR in SF or make HST in central London. You won’t notice the gain if you’re trying to load a page hosted far away from you. In fact latency is way more impacted by the web neutrality but that’s another subject.
- 5e92cb50239222b 3y agoIf you live in a major city close to the target datacenter, maybe. I have an excellent last mile (500 Mbps symmetrical FTTH) and pings to sites like google.com still go above 300 ms. 5G wouldn't help me at all, probably the opposite. The vast majority of that time is spent in data bouncing around the world through very inefficient routes.
- orjandus 3y agowell, you can't go faster than speed of light?
- zeristor 3y agoYou can’t go faster than the speed of light in a vacuum.
- Incipient 3y agoSpherical light in a vacuum?
- onion2k 3y agoYou can find a shorter route though.
- maeln 3y agoThe distance from my city to new york is roughly 5600km which, given the slightly slower speed of light in a optical fiber, would give a minimum ping of ~27ms (one way). Given the same distance but in a vacuum, it would be around 18ms. But if I ping a server in NY right now, my actual ping would be around 100ms (can easily go up to 200ms). Most of the latency is created because of the routing. The farther you are from important peering hub, the worse your ping is usually going to be. When I was living in French Guyana, it was basically impossible to have a ping less than 120ms from anywhere in the world.
- zamadatix 3y agoTo note for others who might be caught off guard: minimum ping over an ideal direct fiber path would therefore be ~54 ms since ping reports round-trip time, not the one-way value.
- 0cf8612b2e1e 3y agoI am curious your use case where latency is currently an impediment. Sure, nobody likes lag, but outside of pro gaming and HFT, where is the need? New York to LA is ~60msec New York to Hong Kong is ~250msec
- aziaziazi 3y agoMaybe GP does not live near NY, HK or any supernode.
- snowe2010 3y agoI was just in Hawaii and it was only 72ms.
- aziaziazi 3y agoDoesn’t Hawaii infrastructures benefits being a highly touristic place and a very rich country state ? In fact Hawaii has multiple supernodes: https://www.submarinecablemap.com/ https://www.submarinecablemap.com/
- 22c 3y agoSeeing the submarine cable maps for Hawaii can be a bit misleading. If I'm not mistaken, a lot of the fibre capacity simply bounces through Hawaii and isn't trivial for the islands to hook into. I don't believe Hawaii itself is any better connected to the internet than say, New Zealand
- aziaziazi 3y agoThanks for the precision. My point was: your latency will probably be more impacted by the number of nodes from you to the destination server than the distance to this server.
- networkchad 3y agoYou are historically accurate. For a long time there was a lot of fiber that physically hopped through Hawaii, but didn’t actually talk to any gear locally (switches/routers). It was just an optical landing/regen station. These days I believe there is less “optical only regen” and more IP-connected links.
- capsicum 3y agoLets wait for Quantum entangled networks. Just 8 pairs of particles separated at ISP level, we have instant hops of data limited in speed by the oscillator.
- empyrrhicist 3y agoThat's theoretically impossible, and not at all how entanglement works.
