Vint Cerf Says No To IPv7, Yes To InterPlanetary Web 108

jbrodkin writes "IPv6 is here, but what's up with IPv7? Nothing, says Vint Cerf. While one day there may be another new Internet Protocol, work is not happening on it now. 'At the moment there doesn't seem to be any incentive for inventing yet another one,' he said in an interview. However, he contends that 2011 will be a Big Year for his pet project, the extraterrestrial 'InterPlanetary Internet.' The 'Bundle' network protocols will be tested in space and standardized to 'make them available to all the space-faring countries.' As they are used with more spacecraft, 'we can literally grow an interplanetary network that can support both man and robotic exploration.'"

    IPv6 is not mainstream yet, and probably still won't be for a while longer. Considering that IPv6 solves the problem of limited addresses in an increasingly networked world, which was and still is the driving force for the migration from IPv4, immediate R&D into the next standard just seems unnecessary. Plus, with how big of a headache IPv6 has been, who can honestly blame 'em for not wanting to think about it for a while.

      Some are hoping for a magical IPv7 that would magically 'just work' with IPv4 without any messy backwards compatible issues. None of those understand the problem, but assume there must have been *some* way to do it without losing our quad-dotted addresses or rewriting or recompiling a single thing. Like 'why not just raise the limit on the numbers from 255 to a thousand or something?' or 'just add another dot-number at the end'.

        You can express IPv6 adresses with quad-dotted notation if you wish, going way over the 255 limit. The truth is that it is the underlying number of bytes in an IP packet header that matters.

        IPv6 addresses range is 0.0.0.0 to 4294967295.4294967295.4294967295.4294967295

        Something with extensible addressing would have been nice, like phone numbers with international area code / national area code / local number, but with an open ended number of divisions. You could refer to stuff on your lan with a single number, possibly within your corporate network with 2 numbers, and so on. When we need to start routing traffic off the planet just prefix another number on there - 1 for Earth, 2 for Mars, etc. A full address might take the form of:

        planet / country / ISP / customer / netw

            Maybe. I was kind of thinking the opposite though... the address tables would be much smaller than IPv4 because you only need to route between levels, and you could do that in hardware by examining the first few bytes of the address. IPv6 has much the same idea but with a fixed length address.

    Delay / Disruption Tolerant Internet (DTN) is still at the Research Group [irtf.org] stage. It's really more about replacing TCP than the Internet (UDP will work just fine in space), and has received some criticism [google.com] (pdf download), ironically mostly centered around how it breaks the end-to-end principle.

    While there is now an SIS-DTN green book [ccsds.org] (a necessary step for general deployment on space missions), and initial tests in space are positive [intersys-lab.org], these things move so slowly that I think it's going to be a while before this is generally deployed in space.

    Dear Earthling,

    Confidential Business Proposal

    Having consulted with my colleagues and based on the information gathered from the Intergalactic Spaceball Chambers Of Commerce And Industry, I have the privilege to request your assistance to transfer the sum of $47,500,000.00 (forty seven million, five hundred thousand Spacebucks) into your accounts. The above sum resulted from an over-invoiced contract, executed, commissioned and paid for about five years (5) ago by a foreign contractor. This action was however intentional and since then the fund has been in a suspense account at The Central Bank Of Planet Spaceball Apex Bank.

    We are now ready to transfer the fund intergalactically and that is where you come in. It is important to inform you that as civil servants, we are forbidden to operate a foreign account; that is why we require your assistance. The total sum will be shared as follows: 70% for us, 25% for you and 5% for local and international expenses incidental to the transfer.

    The transfer is risk free on both sides. I am an accountant with the Spaceball Galactic Energy Corporation (SGEC). If you find this proposal acceptable, we shall require the following documents:

    (a) your banker's name, telephone, account and fax numbers.
    (b) your private telephone and fax numbers —for confidentiality and easy communication.
    (c) your letter-headed paper stamped and signed.

    Alternatively we will furnish you with the text of what to type into your letter-headed paper, along with a breakdown explaining, comprehensively what we require of you. The business will take us thirty (30) Spaceball days to accomplish.

    Please reply urgently.

    The transition to ipv6 is going to be absolutely huge, I'm sure everyone here doesn't need to be told about the complexities of it.

    As far as I'm concerned and I feel I'm probably right, once we go to ipv6, we won't see another protocol implemented in our lifetimes (I'm in my early 30's) period, nada - not gonna happen.
    The bigger the internet becomes, the older it becomes and the more devices attached, the more difficult changing the protocol is. It's already going to be a nightmare, don't expect this will get easier.
    This is like one day telling all Americans "Sorry, no more 110v - we're moving to 240v power" - it's a pretty monumental task.

    So to get to my point, if ipv6 doesn't do what we need or would 'like' it to do, sorry to say but tough shit, someone should have thought of that earlier, because it's going to be here to stay... - of course if you want to see a somewhat faster transition to ipvXX? then just wait until we are completely out of ipv6 addresses, we will then likely transition quicker...
