China Lights Pure IPv6 Network
plui writes "An all IPv6 backbone was launched this weekend in China. 'CERNET2 is the biggest next-generation Internet network in operation in the world and connects 25 universities in 20 cities. The speed in the backbone network reaches 2.5 to 10 gigabits per second and connects the universities at a speed of 1 to 10 gigabits per second.' Here is a link to the story in the English version of China Daily, the online news site in People's Republic of China."
Oh, you can access porn and "subversive documents" all you want in China. I do it everyday.
I guess you're referring to this document. Let's read it again. Why do you need to misrepresent the thoughts of the author ?
Heresy! I shall report you to the Department of Moral Standardization, the Bureau of Political Homogenization, and the Office of Internet Regulation!
But seriously, do you mean through proxies? Don't you worry that you may be caught / ratted upon?
A blog like any other.
... now they can assign an IP for each one of them... next step: switch ID cards to IP cards ;)
The point is outlined in this line of the slashdot plug, "'CERNET2 is the biggest next-generation Internet network in operation in the world..."
That alone makes it newsworthy. But of course, you're right. We should not discuss news items from countries whose values systems are not reflections of our own. I hate all that pesky "world news" stuff anyways. It might broaden my horizons or something, and we wouldn't want that.
Note to self: No more arguing with the faithful.
With all of the advances going on in Asia with regards to IPv6, is this going to result in a large split in the internet as more sites appear on possibly ipv6-only servers?
Most of Europe and the US is seriously falling behind with IPv6, and there's still very little incentive to improve this - chicken and egg indeed. My employer is a large telecom with 1 million ADSL subscribers, but has no concrete plans to roll out IPv6 still, as they see no pressing business need for it. But I fear this will isolate us from the huge economy in asia.
There will soon be a time where there will be a lot if great content on servers that are only IPv6 capable, and these may slowly develop into separate 'internets'. What can be done for the rest of the world (ie, Europe and the US) to catch up on this? We may end up being left behind as asia powers ahead with technology.
But then again, Asia is where most of the newer tech goodies come from, so hopefully we will start seeing more everyday appliances supporting IPv6 natively, which could be the boost we need for full v6 support in the infrastructure.

Can't wait when Google will be available from my IPv6-only network.. ;-(

No proxies. It is not illegal to surf porn or stuff about Falun gong in China. What is illegal is setting up commercial porn sites within China (or dealing with commercial porn in general - your home made porn is legal). It is also illegal to challenge the ruling party, for instance by setting up Falun gong web sites within China. Everything else is legal, and if it isn't, nobody gives a shit anyway (you will find porn behind the desk in any video rental shop in China).
75% of the kids in China learn about sex through web porn. This is in concordance with the rest of the world. Go figure.
The Chinese authorities are very ambivalent about porn. That is why they do some obligatory censoring and let the majority sip through.
Ok, you can live in your closed world if that's what you want. And oh, don't buy anything made in China, including most garments you can find in the US, computers, cell phones, electronics, shoes, ... Yeah, there are other countries which make them too, but as far I know, their political systems are not the same as the american one either....
Well, I don't like to respond to AC, but I'm just tired of this attitude here. Sure, China has a ton of problems (I'm Chinese and I live in China, so I should know), but that's not an excuse that we can't all participate in building a better world. The chinese leaders now are very pragmatic, they still have their little problems, but that's getting better everyday. Do we need a bloody revo to change all this overnight? I'll take the current model of gradual change any day.
What I'm saying is, if you don't care about other countries, fine, just buy everything made in USA. But just get over it, people are moving with their pace.
internet is about freedom? what the fuck bullshit are you talking?
did "the owner of the internet" have a press release I missed on "what it's all about"?
as far as I can tell it's primarily about information and communication, and more recently secondary aims like commerce.
should you have the "freedom" the post information or conduct communications that would be illegal in another medium? no, of course not.
or am I taking your "think of the childen" whining too seriously? was I just supposed to think about freedom, wave a tear from my eye and salute the American flag?
Ok fine, as long as you don't become a problem for the system you're (more or less) left alone... it's called jus murmurandi. Any non liberal political system is very lax in applying such repression so not to alienate the majority of the subdued masses; which are pretty condescending as long as their primary needs are satisfied. But don't worry, the moment you become a threat, you're quite certain there's some obscure, anal retentive prohibition, you'll get fucked over with. It's like having a dog on the leash, as long as it's not pulling you have no reason to strangle the poor sap (unless you're a loony bastard, like Stalin, Hitler, Pol Pot, etc...)

Tell me, Mr. Anderson, what good is a high speed network if you are unable to speak your mind?
". IPv6 is intended to replace the previous standard, IPv4, which only supports up to about 4 billion (4 × 109) addresses, whereas IPv6 supports up to about 3.4 × 1038 (3.4 dodecillion) addresses. This is the equivalent of 4.3 × 1020 addresses per inch (6.7 × 1017 addresses/mm) of the Earth's surface."
It should hold for a little while.
It's enough addresses for many trillions of addresses to be assigned to every human being on the planet.
The earth is about 4.5 billion years old.
If we had been assigning IPv6 addresses at a rate of 1 billion per second since the earth was formed, we would have by now used up less than one trillionth of the address space.

As far as I know, porn is delivered also outside the internet, for instance in form of magazines. And no, you don't have to be literate to read those magazines... in fact, pregnant women are standing all over the country side selling those lewd magazines and video tapes. Pregnant women, because they can by law not be detained for this minor crime.

Enough America bashing! We're talking about China!
From the article: One big benefit of the IPv6 is to solve the problem of shortage of IP addresses. In the current Internet based on IPv4 technology, the United States controls 74 per cent of 4 billion IP addresses, while the amount that China has is only equal to a campus of the University of California, despite its 80 million Internet users.
Although people think that with NAT all IPv4 related problems could be solved here we see a very good reason why the rest of the world could use IPv6. Most of the IPv4 ranges are in the US. The rest of the world just has to get by with whatever is left (Big companies gobbling up entire classes of IP ranges which they never really use should be obliged to gives those ranges back so others can use them).
Would this step be beneficial to the transition to IPv6? With the advent of the internet in other countries then the western world it could well be that things need to be sped up so that we will not see different internets. Has anyone done some real research on this subject? I know i keep hearing that with NAT and similar technologies IPv6 might not be necessary but is that really so given the rise of internet usage in Asia and other countries?
Ok, let's do better, let's assign each cell in these 10^10 people with a single IP address. According to some source, the human body consists of 10^14 cells. Assigning one address to each cell for each person thus equates to the use of 10^24 addresses. Then, we've managed to fill up 10^-14 of the available space. Not even noticable, while we now can address any cell in anyones brain with ease.
You can juggle the numbers in various ways (square foot of earth as another poster said), but what remains is that IPv6 address space is mindboggingly big, and save for assigning every atom on earth a unique IP-address (we would need about 170 bits for that), it should last quite a while before we find ways of wasting enough of the address space that it starts to matter. I'm pretty sure that we'll come up with ingenious ways to do this, but so far my own efforts in this respect have made puny dents in the number. Try to figure out some scheme that (a) makes sense and (b) requires so many IP-addresses that we might conceivably run out in a century or so. Try it, it's fun!
Of course not... but I'm sick of this "bad apple" tripe. While it's not representative of the US's population as a whole (not YOU or your dear nanny and her apple pie), the US Govt. has, throughout the last century thoroughly fucked up anyone's life it pleased. Wikipaedia or any random googling will route you to South America's unlucky fate as US neighbour and playground (banana republic, Chile, Allende, Argentina, Contra, Colombia... hell even Cuba) The US quite simply murdered or substantially helped psycotic dictators more than willing to do so, anyone that got in their business' way. And went on ranting away at Communist threat; which was nothing but exasperated farmers, shit poor bastards that just wished to improve their living standards to humane levels and shrug some robber barons off their back. Jeez, you could have helped them out like you did with Europe; tilt the balance towards socialdemocratic friendly systems but no, you had to go the Rummy way and get the swats in... No, I'm not US phobic; actually I sympathise with 49% you you folks ;-)

Examples:
Fuel -- China is going nuclear and is planning on being a major player in the energy-provider game in the near future.
Space -- China has an active space program, not the joke that the American space industry has become.
True, sometimes the ethics of the programs are a little off, but China is willing to take risks, especially if the payoffs warrant it. America just does not seem willing to take the risks.
If there was any doubt about it, this is more proof the US (and the rest of the western world for that matter)is losing the edge in technology. China and India continue to develop their industrial bases and accumulate the critical masses of professional expertise needed for a self sustaining tech economy.
With cheap labor and a friendly legal and regulatory environment, not to mention a huge domestic market, these countries are taking the tech lead.
We, on the other hand, sit back and cluck our tongues as every nitwit who gets a hangnail is allowed to sue the evil profit sucking corporations who obviously conspire to kill us all for profit.
I for one welcome our new asian technology masters.
I have mod points. The reign of terror begins now.
That's nonsense, we have already run out of IP adresses, that's why we get feature crippled 'name based virtual hosts', 'dynamic IP addresses', 'private networks with NAT',...
IPv4 was intended and assigned for networking big supercomputers, now every single PC got an IP address and every cellphone is going to need one. IPv6 is intended to solve this problem but from all the discussion going on it seems that they have not yet considered the future need of space colonies.
our new Chinese overlords
Is it funny when it's true?
You don't have to remember them!
You know, there's a tool called DNS which just for this purpose...
I moved to China less than 6 months ago - like any move, it is a combination of good news and bad, but the good news, like this, makes me happy I'm here :)
Add in the free HDTV set top boxes, all new subways in this province and living like a king for pennies a day, and the US won't see me back any time soon.
The vast majority of information and communication is from/between people who are not "the press".
"freedom of speech" doesn't have to be total for useful information and communication to take place.
This is a good thing because it doesn't exist anywhere that I am aware of.
How is saying "this isn't true" (which is a fact) a troll? Wait... wait ... do i actually care about karma? I guess not, by typing this mail (which will be moderated OT without a doubt).
Five years ago when I worked for a major backbone provider (Qwest Comm.) and as I was talking to one of the global network engineers, he was wearing a shirt that had a Qwest logo and an IPv6 network under it. I asked him if that was for Qwest's IPv6 netblock and he indicated yes. We talked for about 15 minutes during which time he explained that Qwest, along with others like MCI/Worldcomm and AT&T (and several other big names you'd recognize if I cared enough to list them all), had a "parallel" IPv6 network running across the U.S. and some of them were even passing live internet traffic over these routers using encapsulation. However, the routers knew each other by their IPv6 address space.
So, five years later, how can the poster say CERNET2 is the biggest IPv6 network in the world? I would say "prove it". I would think several large international backbone providers who had links with each other passing live traffic would be considered pretty damned big!
did "the owner of the internet" have a press release I missed on "what it's all about"?
Why, yes I did.

The network hit full capacity less than 48 hours after coming online. Analysis reveals:
53% of traffic was bittorrent
38% of all traffic was spam.
31% of traffic was porn.
22% of traffic was due to windows viruses and spyware.
17% of traffic was first-person shooter games.
13% of traffic was VoIP.
8% of traffic was Slashdot-related.
3% were Last Pages of the internet.
0.13549% of traffic was scientific data.
Note that Spam is 46% of all e-mail traffic and bittorrent is 43% of all P2P traffic.

- - You can't take something off the Internet! That's like trying to take pee out of a swimming pool.
- The shortage of GUAs (Global Unicast Addresses) is only half of the problem. The other part is route fragmentation. The defaultless routers (Those routers that route your packets safely through the backbone mesh) have a routing table of about 60.000 routing entries. It is a bit like fragmentation of a 96% full harddisk. The shortage is not only limiting you on placing new files, but it is also causing the file system to be inefficient.
- Let us first make clear, that there today is only a plan for about 15% of the address space, so before anybody starts rabbling, 85% is not only not in use, by is not even assigned a purpose.
- The IPv6 addresses has, like IPv4, a net part and a host part. Where this is variable in CIDR IPv4, it fixed in IPv6 to 64 bits. Every produced and future ethernet card will fit into one big flat switched net. Besides the full 48-bit MAC address, there is 16 bits for the EUI-64 extention which will be applied when new generations of network links are put in production.
- The largest part of the IPv6 address space is used for AGUA (Aggregatable Global Unicast Addresses); it is the 12.5% of the planned address usage. It is called so, because the allocation is done like CIDR addresses, based on where the main connection is routed to. There is reserved 13 bits (8192 combinations) for TLAs (Top Level Aggregators) which is large backbone providers like UUnet, PSInet and others of this size and extension. Each TLA slot will provide 24 bits (16 mill. combinations) for handing out to NLAs (Next Level Aggregators) in how many levels the business is shared (large ISP selling to small ISP). The customer will get 16 bits (65536 combinations) as a SLA (Site Level Aggregator) to make subnets with (You will get more subnets than you ever could dream of getting IPv4 individual address today). On top of this there is 8 bits reserved for future needs between the TLA bits and the NLA bits, but since we don't know where the shortage may be, decissions can be applied later.
- There is also reserved an address range for private address space. LLAs (Link Local Addresses) are auto configured addresses given to each interface as it is activated. There is also SLA (Site Local Addresses) which more ressembles the private address ranges (10.0.0.0, 172.16.0.0, 192.168.0.0) and is assigned by a local adminitrator's discretion. This about a half percent of the address range, but in practice is not possible use more than a fraction of it, for other reasons.
- Multicast addresses is also assigned a range of about a half percent, and also is for practical reasons only useable in a fraction of the space.
- Adding compatibility addresses for IPv4, IPX and OSInet this amounts to 15%.
When you then take into account that there is work being done on dynamic assignment of address ranges by need and anti-fragtional measures. The endresult is hopefully that we will never need to give IP addresses any more thoughts than we today gives the actual routing of packets.:-) = I am happy
