Building the Interplanetary Internet
sighted writes "Internet pioneer Vint Cerf, now a Google VP, is leading a NASA effort to create a permanent network link to Mars within the next two years. As Cerf outlined in a recent talk, the 'InterPlaNet' protocol is designed to handle the delay caused by interplanetary distances. A signal traveling between the Earth and Mars can take up to 20 minutes."

My parents recently moved my family to Mars. I'm an avid gamer, but I'm now having a hard time playing online games as my ping is frequently 20 minutes or more. I've added 8 CPUs to my network card, but it hasn't helped the situation any. I'm wondering if anyone has found any solutions to this problem? I'm looking into using wormholes or possibly bending space-time in some other way, but I'm just not sure where to direct my efforts. I really miss playing Doom XV online, and I hear Duke Nukem Forever will be out soon, so any help would be appreciated.

This would be a protocol that would bind in with TCP/IP. Former space missions used protocols invented by the companies that built the hardware, not necessarily a common framework. This should change all that...

RFC 1149 already documents how IP can be implemented with high latency low reliability environments. You don't really need to be re-inventing the wheel. Although I'll admit, a spacegoing pigeon would present an engineering challenge, so you might just want to stick with something a little more conventional like radio. But you can probably adapt the latency part...
On the bright side, the latency of someone on Mars playing against someone on Phobos isn't that bad.

We have a couple of druids who are just horrible healers. I thought it was because they recently moved to Mars, but it turns out they're just feral specced.
Mars is, roughly, between 50 and 250 million miles away from earth, depending where we are in our solar orbits. Recently, the closest it's been in a long while is nearly 35 million miles (back in 2003 according to the Intertron)... but the distance swings rapidly as we race around our orbits... it can go from 40 million to 200 million in the space of a few months. I'm using 50 million as a rough average for the sake of illustration.
Given the speed of light, as fast as we think we can go, is *only* 670 million mph... that means the fastest one way trip we think anything can do is still going to take 4.5 minutes... it'll be better when it's closer (just over 3 minutes) and worse when it's on the opposite side of the sun (22 minutes)... and remember thats just one way!
Even if we plant a colony on mars, you won't be seeing ms ping times between earth.sol and mars.sol until there a breakthrough in our understanding of physics and we figure out how to go faster than the speed of light.
For those who didn't want to bother to read this post, if you want to play Halo XXV on a Mars server, you'll need to figure out a way to communicate with that installation at superluminal speeds.
With a twenty minute delay, the standard practice of resending dropped packets becomes more prohibitive (the send/NAK/resend would take an hour!), so you'd have to make the encoding redundant enough so that most errors could be recovered by the receiver - without doubling the bandwidth. Oh, it would be fun!

It's silly to be talking about Mars bases, etc., when we haven't even done a sample return mission yet. A sample return could go a long way toward settling the question of whether there's actually microbial life on Mars.
As this stuff gets more complex, it totally makes sense to do anything you can do to cut down on the complexity. If landers only need a low-power radio, and a low-gain antenna, in order to talk to a permanenet orbiting comm satellite, that's a big reduction in complexity.
Another logical step would be to establish fuel depots of liquid oxygen, on the surface and/or in orbit. You've got free solar power, and in orbit it's really easy to get things cold enough to keep oxygen liquid. Otherwise any mission that's going to come back to earth needs to carry the fuel for the burns on the return leg, and that increases the mass you need to send to Mars, which increases the fuel requirements even more.

Just an idea why not used entangled atoms to bypass this distant problem?.

I read that book as a child in the sixties in translation and I loved it; upon reading it I figured out that communism was not so bad after all (despite what everybody told me).

My wife doesn't listen to me either...
A communication network of sats were planed for Mars. W's budget killed it. I have been thinking that perhaps a system of nanosats could handle the comm, as well as provide a simple GPS and other sensors (different sats carry different sensors, some could carry simple camera, etc). The interesting thing is that the same thing can be used for the moon to enable comms anyplace on the moon esp while traveling on the backside. This is because the Martian atmosphere is thin enough that even a slow uhf radio would work.
I prefer the "u" in honour as it seems to be missing these days.
UUCP and USENET were good analogs, with "latency" usually being "less than an hour" or "less than a day" but sometimes "less than a week. Heck, there was one outfit that got USENET feeds by TAPE every week.
A 747 full of HD-DVDs or Blue-Rays has high bandwidth but terrible latency.
Any reason UDP's "send and forget" with an appropriate application- and link-level protocol can't be used? Of course, this would only be useful for non-latency-sensitive applications, such as a scheduled "push" of data, where the schedule was set up ahead of time. Given the chances of error, it should also have lots of error-correcting bits at the link level and a delay-tolerant error recovery at the application layer.

Have you not read about the TSP/LP connection done using carrier pigeons? This has been used for Comp Sci teachers for years as an example of how network "layers" work such that TCP is over Ip is over the physical link and how you can swap out layers without effecting the other layers. It was purly just a teaching point, until a few years ago...
Then it was done for real, using live birds to carry the data. I think they tried a Ping and maybe a telnet session. There is a real RFC written up on this. Note that the "time of flight" delays are on the same order for the pigeons as for the speed of light delays to mars. SO, this problem has been solved once.
Actually, I think it's only TCP that needs to have a window adjusted due to the delay. The IP packets don't care how long it takes but the TCP layer will start doing re-transmits if acks don't come back within a window.

According to our current model of physics, no information can be transmitted faster than the speed of light. IIRC, the problem arises from the entanglement being destroyed when you observe the atom and the inability to make sure that you're measuring the right thing without communicating through some other means.

NTP can handle lag to refine the local clock setting but what time standard will Mars adopt?
I can see treating the whole planet as GMT then having some local time standard for min/hrs/days/years and having the local o/s translate GMT into the local standard.
Will there be DST?
Is there a rule that says we must wire up planets one at a time and that we can only start on one planet after we've finished the previous one?
Doesn't it make you feel good to know that our freedoms are protected by politicans, lawyers and journalists.
Since it takes 15 or 20 minutes for light to travel to Mars, the correct window size is something like 39482396347044987234982432948.

Confidential Proposal/Investment Assistance.
Greetings and love to you in the name of the most high Xenu from my beloved planet Mars. I am sorry and I solicit your permission into your privacy. I am Martian Barrister Bob N'g'w'll'ac, lawyer to the late Prince Grunthor eldest son of the late former Emperor of Mars late Warlord Xandor.
My former client late Prince Grunthor died in a plane crash in the year 2094. Upon the death of my former client and unknown to the family that is currently under house arrest and undergoing prosecution in the hands of the present administration as a result of human right violation and looting of the planet's treasury by the late head of state Warlord Xandor.
Before the death of my client he had deposited 90,000,000.00 Martian Mega-bucks with a secret security firm in two trunk boxes in my name, and I am the only authority to this fund which he was to transfer off world few days after he died in a plane crash.
This fund was deposited with the security firm in my name because my client stole this fund from the planet's treasury and he did not want anyone to know that he is associated with the fund in question not until the fund is successfully moved off world.
The security firm does not know the actual content of the trunk boxes, my client and I told them that the boxes contains old Martian artifacts to be delivered to a client off world via Interplanetary Courier Services. For now it is only you and I that is having knowledge of this fund, and the only assistance I require from you is to help me receive this fund in either Amsterdam, London or Spain depending on our country of agreement and possibly invest it abroad in your area of advice.
This fund shall be disbursed accordingly as follows: 25% for the recipient (you) from the total sum(90MMMB). 2% for the courier officer in the country where you shall receive the trunk boxes. 5% set aside from the entire sum for expenses incurred by both parties in due course of executing this transaction (home and abroad). 68% for me.
If you are not satisfied with the percentage sharing of the fund feel free to let me know. In compliance with this you are to immediately forward to me by mail the following: Your full names and address Confidential space phone and space fax numbers.
With this information I will immediately commence all necessary documentation for a successful shipment of the first trunk box to your country of choice as all the modalities have already been worked out by me. I will also give you full details of this whole transaction which I have already perfected in due course.
Please note that you are to treat this with utmost confidentiality willing or not willing to assist me in this transaction as nobody knows about this fund and I am still an active lawyer in this country.
THE CHOICE IS YOURS, IF I WERE YOU I WOULD, BECAUSE IT WILL COST YOU LITTLE OR NOTHING TO ACHIEVE THIS AND THE BENEFIT WILL CHANGE YOUR LIFE FOREVER.
Remain blessed in the name of XENU.
Yours faithfully Martian Barrister Bob N'g'w'll'ac

As a technical concept, this is reasonable, since NASA historically has used their own proprietary protocols, even between ground stations and on equipment buses. Spacewire is an example. In the early days of the space effort, this was necessary, but today, NASA tends to have people on staff re-inventing the wheel.
But it's not a big deal.

Interesting problem, even if talk about an interplanetary internet has been around for years.
There is a major difference with earthbound networks in that you may need to include a good amount of dynamic knowledge about things like orbit, revolution, local time, and the region of space a node is operating in. If the Earth is on the other side of the sun you presumably need to have nodes at trojan points - or maybe just one at the north or south solar pole - to relay. That point will be subject to solar storms too - more if you want it to be closer to earth and a shorter light speed hop. Maybe the routers need to know system geometry then, and be able to calculate when a station will be facing its antenna towards it by the time the signal it send reaches it.
Perhaps Martin Lo's Genesis project would be useful for mapping slow paths for routers (all routers will be spacecraft in motion somewhere) which will require minimum power to keep them on a predictable course. Seeding his interplanetary superhighway (a major discovery that the solar system is filled with tube-like paths where gravity likes slow ships) with a sequence of router-equipped craft, might be the way we are going to roll out this network. The routers closest to earth will be more advanced and with the latest information about near-earth network and space activity, so perhaps the protocol should include the ability to be configured to weight favorably craft that are closer Earth for example.
Though Vint or somebody has said they could run IP over carpet static, the only thing I can see that might be carried over is the idea of a URL and a domain name. But even so, for a spaceship moving between two planets, you don't really want to force it to logically belong to a planet. More like having it belong to a virtual controller (like the router for a fleet of satellites) that itself gets passed to different stations' jurisdictions if the fleet moves. I guess the problem I have is that it sounds like they are starting with the idea of an Internet that works hierarchically or like mobile phone cells. But then you have to go "roaming" when you move. In space, everything moves! And time? How can we even tell time when the earth is dragging its frame around with it. Okay we can all standardize on the sun or a star or something. It is so complicated that the only thing for sure is when that machinery gets far away it will be a pain to mess with it. This all has to be completely reburnable, reconfigurable, and idiot proofed so we don't run the risk of bricking the network before we figure out how to get it to work. This might be a good time to start thinking of how to control communications with a solar orbit spanning radio telescope, or those nanosatellite fleets people were experimenting with recently.

Here's a metric for you to use: If it were that easy, somebody would have done it.
We're talking almost-guaranteed-Nobel Prize work here.
Not to mention every damn time the speed of light comes up on Slashdot, somebody babbles about entangled particles. Again... if it were that easy, it would have been done.
Google for why it's not possible.
They should look at ALIENTP. I proposed it (and eventually developed and tested it) 2 1/2 years ago. Vint Cerf is SO behind the times.
--<Mike>--
Not possible according to wikipedia:
As a result, measurements performed on one system seem to be instantaneously influencing other systems entangled with it. But quantum entanglement does not enable the transmission of classical information faster than the speed of light (see discussion in next section below).
and here:
Although no information can be transmitted through entanglement alone, it is possible to transmit information using a set of entangled states used in conjunction with a classical information channel. This process is known as quantum teleportation. Despite its name, quantum teleportation cannot be used to transmit information faster than light, because a classical information channel is required.
Unfortunately, the vast majority of routers in use today implement "martian packet filters" in their TCP/IP stacks...
You can transmit information this way, but not faster than light.
The problem is that whenever you observe one atom, the super-position collapses instantaneously for both. That means the receiver needs to know that the sender has already measured the atom on the sending end before observing their atom on the receiving end, this would have to be done by a standard, non-FTL signal. You also have the problem of not being able to collapse the super-position into a specific value (say 0 or 1), so while the receiver would know what state the sender's atom is in, that state is a random value (0 or 1), so no data is actually conveyed.
The first problem may be overcome with some time-based scheme, where the sender and receiver have syncronized clocks, and have agreed at what time the sender will measure his atom. The problem with random waveform collapse, however, would be harder to overcome, though I think the quantum computers in recent articles have managed to make it slightly less-random.

Never mind the fact that it would take 4.39 years for a packet to arrive from our nearest neighboring star system! Server down? Oops, wait 4.39 years + 5 minutes to get a timeout, and then try again.

The saddest poem
Sigh. ok, this is tech support.
./qemdriver.scr and hit enter. You -did- save it to your home directory, didn't you?
It sounds like your system is reverting to radio frequency transmission, you need to get your QEM up and running correctly before you can play real time. Didn't you RTFM?
Do you have your QEM (quantum entanglement modulator) correctly connected? Is it plugged in?
Go from the K symbol to Utilities to Hardware. Now, see if you can find if your QEM has been detected by your system. If not, you are doing to have to download the driver from Sourceforge the old-fashioned way. You can use this time for a snack break. The connection will take 35 minutes to set up day, at our current distance. And then you have the download to wait for.
Once you have it, you will have to open a terminal and type
Assuming you have no dependency issues, it should install. At this point, you need to reboot.
During the start-up screen, look to see if it loads correctly and your QEM is correctly identified.
When you are fully booted, you need to go to K ->Utilities->QEMConfig, and follow the wizard carefully. This is important. If you do not follow the directions exactly, you may end up sending information into the past when you try to use your InterPlaNet connection. This has been known to happen from time to time. Some historical researchers have found that some of these incidents were taken as April Fool's jokes back on Earth in the old days. You really don't want to do that, it is embarrassing.
Ok, if that doesn't work, call again.
Goodbye.

It is OK if you play turn-based strategies. In fact, this is not a problem at all for games that are not designed to be played in real-time.

Quantum Mechanics isn't magic, and can't pass information faster than c.
Implement a generic solution to handle the packet loss when the sun is between the Earth and Mars. This solution should not rely on hardcoded values or tables. In addition, it should be easy to alter, in case the client wishes to change the orbital paramaters of either planet.
Sure, but that doesn't help if your packet gets rejected by the martian filter on the firewall....
Probably some sort of encapsulation would be necessary.

"A signal traveling between the Earth and Mars can take up to 20 minutes."
The signal could take much longer than that, considering that just about every other year, Mars and Earth are on opposite sides of Sol.
Part of the project is going to involve creation of satellites around the sun between Earth's orbit and Mars's orbit which allow information to be relayed through them between the planets. I suppose 3 would be a good number. This should be an interesting story to follow.
If you can read this, I forgot to post anonymously.
I wouldn't trust too much an article that states that the Jet Propulsion Laboratory is in Houston, Texas (instead of Pasadena, California) ...
With a 20 (40?) minute RTT, and a Gigabit (100M?) radio link, you could store a fairly large amount of data short term on the network. Wouldn't want to use it for anything critical though.
20m * 60 = 1200 seconds
1200s * 100MB / 2 (error correction) = 60000MB = 60GB
hehehe.
Stupid.

So if something like the sun gets in the way and blocks/distorts the transmission, can signals be routed through satellites put in place near Mercury or Venus? Given how rarely the first 4 planets line up, it could be five 9's. ;-)
Allowing people to die in order to make a few bucks is illegal in any civilized country I think...
Except you forgot to apply the formula...
number of people * chance their families will sue * average cost of out of court settlement = X
if "few bucks" > X - who cares?!?
if "few bucks" is less than X - issue press release pointing out good corporate ethics, and how many lives were saved, due to a policy to "wipe out corporate greed". insert video clip of CEO eating lunch w/ commoners.
Yes, but maybe it's possible but not easy.
think of entanglement like this... you have 2 pieces of paper, one black, one white. You put them each into separate envelopes, then randomly send one of them to australia. At some later point you both open your envelopes. You know what you sent out based on what is in your envelope. Spooky action at a distance but still does not allow for information to be passed faster than light speed.
why every topic must begin with 40-50 joke comments modded up to 5?
...but Mars also needs women so this should help in a virtual kind of way.
So that's how Weyland-Yutani responds so fast when you tell them you've caught a live acid-bleeding Alien... And here I was thinking a response from the evac team would take days!

I don't know the outcome of the retrocausality experiment, but if it was successful, you could possibly send your information 20 minutes back in time, transmit it at c, and get the appearance of real-time communications to/from Mars.
Just put my Nobel in the mail.
Forget thrust, drag, lift and weight. Airplanes fly because of money.
Not that big a problem. Packets getting scrambled by solar radiation, though...
They could send 10 000 lawyers into the dead cold of space?
Now that's the way to start colonization of space.
My other SIG is a Sauer.
So what you're telling me is we've found a faster than light transmission method of a pseudo random number generator seed? Sweet!
http = hypertext transport protocol; www = world wide web therefore gww = galaxy wide web
Remember, the protocol is (or should be) independent of the application...
It's official. Most of you are morons.
The problem lies in possible transmission errors, of which there are many.
Can you say "Forward Error Correction"? (I KNEW you could!) This stuff has been under development at LEAST since Hamming, just after the end of WW II.
Take a look at the guts of WiMax and WiFi, for just a sampling of the ways you can use a little redundancy to repair a lot of broken bits.
From there handling interplanetary distances and channel conditions is just a matter of degree, not of additional breakthroughs.

ISTR reading a story (by Isaac Asimov? ) where humanity was just starting to develop interplanetary space travel. Light speed communications proved a problem because the send-ACK cycle was so long. The solution was the 'mother-in-law' [1] mode, where both ends just keep sending information without waiting for axknowledgement from the other party.
1: it's been too long so the details are fuzzy
Now that samsung's gone into building gaming systems among the many computing products they make, I don't think it'd be worth it for me on Mars to buy all the quadrabytes of switches in the machine because they'd take up valuable cargo payload capac. and space on a earth-to-mars transporter, since all I want to do is game on it. It's not storable memory, so it'd just be wasted for gamers. And even for those considering doing very light graphics developing with it, I think such a half way system is probably a waste because half way developers probably aren't as effective as real developers, so they'd be wasting cargo capacity that should be spent for professional machines.)Reception of plans for computer gaming systems in the future possibly...
The solution is obvious: move Mars closer to Earth. It doesn't matter how ridiculous an amount of effort it would take, or that it might seriously fuck up the cosmos: There's money to be made here!
It's not so much the amount of effort, but the amount of time. We could probably move Mars closer to the sun, even add an atmosphere to it, it would just take on the order of thousands of years. Maybe once we can extend the human lifespan to hundreds of years, we as a species can start thinking and planning on the order of thousands of years.

I think I have about an hour after lunch, that should be enough time to work out the kinks in your suggestion.
