Vint Cerf Plugs Android Into Interplanetary Net

kdawson posted more than 4 years ago | from the hot-dead-birds dept.

The Internet 69

Several readers sent in an update on DTN, the interplanetary Internet protocol that Vint Cerf has been working on for many years (and we have been discussing for nearly as long). The news now is that Cerf has added a DTN stack to the open source Android code, seeing uses in mobile applications for a protocol that does not assume a continuous connection.

DEAR SIR/MADAM:

I am X'Fdfd'hdfsa St'uun. Auditor of the First Bank of Venus. I am contacting you on this business of transferreing US $35 MILLION DOLLARS into a safe Earth account and the need is very urgent.

I got your contact from the Venusian Chambers of Commerce and interplanetary family directory and it is with business trust that made me to contact you on this matter.

I write to solicit for the transfer of this money into your account. This Money was generated from an unused Account in my Bank (FBV).I am contacting you for your help and partnership for the following reason:

My present financial resources will not be sufficient for me to handle the transfer alone successfully without financial assistance from a reliable foreign partner on another planet. 40% of this sum would be for you as compensation for using your Bank account in transferring this money, 10% would be used to reimburse the expenses made by both parties during the processing of the transferring which include,DTN bills, travelling expenses and fees, and starship fuel. While 50% is for me. Please note that I will arrange to meet with you immediately after the successful conclusion of the transfer, the 50% share of mine will be used for investment on Earth. Your assistance and co-operation is highly needed. I assure you that this transaction is 100% risk free. If you are interested I will require your banking information as mentioned below: 1. Name to be used as beneficiary and beneficiary's address. 2. Your private and confidential telephone/ fax number(s) 3. Your banking details and address, your bank Telephone and fax number(s).

Metasquares (555685) | more than 4 years ago | (#30006762)

That's New York City (and for good reason). In NJ we measure everything by exits on the highways :)

But getting back to the original discussion, on a galactic scale, distance and time are scaled versions of the same thing anyway, since everything is traveling at a fixed maximum speed. Something 1 ly away will have a minimum latency of 1 year (2 for the round trip) unless we figure out how to send information FTL. And when you're dealing with distances of thousands of ly, you really wouldn't care about a few seconds here or there due to other overhead.

Re:Vint Cerf Got the Ill Communication (3, Insightful)

RivieraKid (994682) | more than 4 years ago | (#30006242)

If you have a constant speed (i.e. the speed of light), then units that normally describe duration can reasonably be used to indicate distance, especially over great distances.

Think of the light year mentioned above. A light year is the distance that light can travel in a year - so we're using a unit of time to describe distance. It works because the speed of light is the same regardless of your frame of reference, which also means the distance is the same regardless of your frame of reference.

Re:Vint Cerf Got the Ill Communication (1)

> A light year is the distance that light can travel in a year

In a vacuum!

> It works because the speed of light is the same regardless of your frame of reference

Only in a contiguous medium. The speed of light varies in different media, so the time / distance relationship becomes more complex if part of your journey is through water ( c 30% slower ), solid glass, peanut butter, diamond...

Re:Vint Cerf Got the Ill Communication (5, Informative)

RivieraKid (994682) | more than 4 years ago | (#30006666)

Well, yes and no.

The effective speed of light changes in different medium, but only because of the refractive index. The light is still travelling at the same constant speed but because of the refractive index, it's not travelling in a straight line so it only appears to travel slower.

What you refer to is the speed of propogation of light through various transparent medium [wikipedia.org] . The light is delayed due to absorbtion and re-emission, but is not slowed down.

Even experiments to slow and completely stop a beam of light (say, in a Bose-Einstein Condensate [wikipedia.org] ) are really just affecting it's effective speed, effectively capturing it with "tiny mirrors" but the absolute speed of the light is unaffected.

You miss the point. They're not adding DTN to the mobile for extraterrestrial communication - they're adding it to the mobile for better terrestrial communication.

The situations this protocol is designed to deal with - intermittent connection with variable (and potentially high) latency - are things that apply very much to mobile devices.

Packet radio? (4, Interesting)

If "the gumment" shuts off the internet, they will also revoke your HAM license, don't you think? Do stock up on transmitters, and dust off your electronics textbooks, and do get the license if you are so inclined, but the license itself is a joke.

Re:Packet radio? (1)

geekboy642 (799087) | more than 4 years ago | (#30007724)

HAM requires two people with equipment that can be hidden inside of a large suitcase. The Internet, I'm reasonably assured, takes rather more space to store. Even in the doomsday scenario where the tubes are completely closed, and all HAM licenses are revoked, there will still be amateurs using the airwaves. Good luck communicating over IP when the backbones have been cut.

DTN != Protocol (5, Informative)

pdxp (1213906) | more than 4 years ago | (#30006920)

Several readers sent in an update on DTN, the interplanetary Internet protocol ...

Please stop screwing up the meaning of DTN. Not just /., but everyone writing article about Vint Cerf and "his" interplanetary internet. The acronym stands for Delay Tolerant Network, and is a type of network in which connectivity is ephemeral and a contemporaneous path between two points often doesn't exist at any point in time, necessitating any communication to be tolerant to delay (and/or disruption).

A DTN protocol is one that takes advantage of the ephemeral connectivity of DTNs, usually along the lines of employing the store, carry, and forward approach to getting data from A to B via a time-varying path; e.g. a path exists, just not at any point in time.

What Cerf has done has create a bundle forwarding protocol stack for the Android. It's not as "out there" as you'd think- someone send you data, you carry it, then forward it later. Lots of questions/issues in between as you might imagine.

I think some people like Kevin Fall need to get more credit for their contribution to this area of research.

Disclaimer: I am NOT Kevin Fall but I am a network researcher, specifically in the area of DTNs. No, not the algorithm.

Re:DTN != Protocol (0)

That sounds exactly how "Fleetnet" works in the Axis of Time trilogy, once the 2021'ers get dumped in 1942 and no longer have access to satellite communications. When someone previously in Hawaii arrives in Los Angeles, carrying their flexipad (PDA/laptop-like device), it hooks up with other nearby devices and the owners of those devices receive the messages sent by other folks in Hawaii, not just those from the owner of the pad that made the trip.

Non-continuous connections (1)

HTH NE1 (675604) | more than 4 years ago | (#30010182)

Verizon apparently agrees that a data call on a cell phone isn't considered a continuous connection. I was with Alltel using #777 to get slow data calls for free. Since they became part of Verizon, I discover Verizon treats these data calls not only as consuming voice minutes, but also that they consider the connection as starting and stopping for any lull in traffic and round each one to the next minute. Over a period of 2 hours I'd used 130 minutes, and at a charge of 40 cents a minute due to having run out of minutes.
