    from ipv6.org IPv6 is short for "Internet Protocol Version 6". IPv6 is the "next generation" protocol designed by the IETF to replace the current version Internet Protocol, IP Version 4 ("IPv4"). Most of today's internet uses IPv4, which is now nearly twenty years old. IPv4 has been remarkably resilient in spite of its age, but it is beginning to have problems. Most importantly, there is a growing shortage of IPv4 addresses, which are needed by all new machines added to the Internet. IPv6 fixes a number of problems in IPv4, such as the limited number of available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routing and network autoconfiguration. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period. It prevents spoofed UDP backets (no more easy, D.O.S attacks, and spoofted packets) It makes the amount of posible adresses so large that worms that use simple seek algotrithems (such as slammer) would take like 20 years to infect enough systems to do any damage and would allow for all the future embedded apps, to get their own ip's.

      What you are refering to is the QOS field, which exists in IPv4 (what we currently use) and IPv6. However it isn't commonly used in IPv4.

      However, what usually happens is most routers ignore the QOS bits.

      As for the slow downs, etc. That may be your upstream (ISP), who may twiddle the bits, but they can only do that based on a number of factors, to/from port, IP address, bandwidth usuage, etc.

      There is nothing (much) you can do to avoid your ISP slowing down certain connections, except by making it hard to identify what is "legitimate" and what is "illegitmate" traffic. Eg giFT uses random port numbers of both sides, so its very difficult for the ISP to say, lets throttle giFT traffic. Freenet does much the same thing.

      IPv6 will not answer the bandwidth and traffic shapping problems, all it will answer is the limited number of IP addresses problem. (And if you think about it, probably cause more bandwidth problems because you'll be able to have *LOTS* of different devices all plugged into your upstream bandwidth, all sapping it).

      My recommendation is if you live under a draconian ISP is one of the following:
      1) Move ISPs. If All ISPs are like this, move country.
      2) Go postal, grab yourself a semiautomatic assult rifle, storm into your local ISPs NOC (network operations centre), and demand a 100mbit connection for your laptop, "right this instant!".
      3) Find an open proxy, use that to bypass port based traffic shapping. If your ISP is shapping every port but port 80 (web), go find an open proxy that is running on port 80 and use that for other connections. The best bet would be find some willing (or otherwise) machine somewhere outside of draconia, and put a SOCKS proxy on port 80 on the machine.

      4) Implement IP over carrier pigeon. Pigeons are not known for looking at each IP packet and flying differently because of its contents, though if the packet size is too large, it could slow the transport mechinisim down. I'm not sure if this RFC supports IPv6, but sinces its a transport mechinisim, I should think it would matter.

Some experimental implementations of IPv5 are in limited use but mostly outside the United States. You won't see many references to "IPv5" but you may encounter it by it's experimental name, "ST2" or "ST2+". This stands for "STreaming" protocol. Here's what RFC 1819 says about it:

      The Internet Stream Protocol, Version 2 (ST2) is an experimental connection-oriented internetworking protocol that operates at the same layer as connectionless IP. It has been developed to support the efficient delivery of data streams to single or multiple destinations in applications that require guaranteed quality of service. ST2 is part of the IP protocol family and serves as an adjunct to, not a replacement for, IP. The main application areas of the protocol are the real-time transport of multimedia data, e.g., digital audio and video packet streams, and distributed simulation/gaming, across internets.

      ST2 can be used to reserve bandwidth for real-time streams across network routes. This reservation, together with appropriate network access and packet scheduling mechanisms in all nodes running the protocol, guarantees a well-defined Quality of Service (QoS) to ST2 applications. It ensures that real-time packets are delivered within their deadlines, that is, at the time where they need to be presented. This facilitates a smooth delivery of data that is essential for time-critical applications, but can typically not be provided by best-effort IP communication."

      IPv6 is an attempt to return to the principles that gave the internet it's growth and democracy in the beginning:

      Dumb network, smart edges.

      When IPv4 was designed, there was no plan for exponential user growth outside of military/R&D/education. If there had been, addresses would've been 48+ bits from 1980 onward.

      The failing with pre-existing networks which IP was meant to surmount is that the interior of the network was too intelligent. That sounds like a good thing, but it means that the network as a whole is less flexible- the inner nodes (routers) cannot be easily upgraded to support new applications and features. Under IP, all interesting computers are into hosts on the edge of the network. Each can be upgraded by an end-user, without supplication to the network templars- be they Bell Atlantic frame relay technicians, or Novell NOS admins. Those smart edges are served by a dumb cloud- the rest of the network just passes data from one place to another, without translating or modifying it in anyway. In the past, network application growth was slowed because users couldn't easily tell what was going on inside the cloud. IP made the cloud's job boring, so that you were no longer interested in seeing what went on there.

      That change triggered the explosive growth of computer networks until they combined into the shared entity we all know and love.

      NAT betrays this heritage

      NAT boxes move intelligence back into the cloud- instead of IP packets being routed to the desired host and no other, there are now entities hidden in the cloud which waylay your packets. They seize them, pull them apart, inspect their innards- then, maybe, they'll deign to alter the packet and send it along further.

      The damage isn't just a theoretical one- real end-users are being held back by NAT and other violations of the IP promise. New applications which would be easier to deploy with real per-host addressing are difficult or impossible to install reliably. This is things like high-speed game servers, file/web servers, P2P clients, cheap VOIP, videoconferencing, VPN, and prehaps things that haven't been invented yet.

      The internet should be about giving power to the users on its edges. IPv6 would encourage that, but NAT hinders it. There are forces who don't want to empower users- major content providers and big ISPs. (Which may be the same thing). Fearful of losing control of mass audience's entertainment patterns, they want to keep mass creativity centralized. AOL doesn't want users to download ClickNRun IRC-like servers to create TeenTalkDaytonville chatrooms, they want to sell them as a value added service. Time Warner doesn't want 100s of cheap FTP servers passing out free copies of 56 year old TV shows (which by rights are public domain), they want you to wait for the DVD or PPV options.

      The desire exists. A chicken in every pot, and permanent IP address in every study! The powers that be are fearful, though. The existing entertainment/datacomm oligopoly was harmed enough by the Internet. End-users sharing data amoung themselves could ruin them- but the exhaustion of IP addresses provided an excuse to keep end-users cordoned off from the real internet. They could download, but not serve files- as long as the people remain "consumers", the corporations can keep them under control.

People think that some how static IP addresses will magically make things better, but that's only because they are changing the network protocol to fix a problem in the application layer (i.e. name look-ups).

      A better solution would be to fix the directory services at that layer so that IP addresses were not used inside applications. That would also make a transition between IPv4 and IPv6 easier if the applications got their out from being too deep into the network directly. (I.e. get rid of fixed port numbers for specific services, use the equivalent of SRV records or such to let the network layer figure out which port and IP address to send the packets to -- by allowing ports to be looked up as well as IP addresses, that would allow mulitple servers behind NAT behind static port mappings.)

      NAT has no effect on transport. You put data in, you get data out. The only reason that NAT seems like a 'hack' is because of bad coding design that has integrated far too much transport-level network information into the applications. If applications and name-look up were written properly, not only would switching applications to IPv6 be trivial because of less internal code dependence on IPv4 rather than a generic network/transport API, but NAT wouldn't be a problem, either.

      The static IPv6 address auto-assignment is going to be fun to watch. Suppose the network admin doesn't do DHCP, and just lets all hosts auto-configure. Now, there are a couple things that happen -- the hosts choose random host network values -- makes no sense because the whole point of this is to have a static IPv6 address, right? So, host ABC always chooses the same host part of his IPv6 address (perhaps from his MAC address, which now gives his computer the equivalent of the Intel CPU serial ID number), or some other fixed value. What stops someone else from trying to swipe that same value on the network? Your computer reboots, and when it comes on, there is another host claiming to have that MAC/host address on the network already -- so much for that static IPv6 address. No smart network administrator is going stick their hands into that one -- either things will be dynamically autoconfiguring, and static IPc6 addresses may or may not happen depending on your luck and your neighbors, or the admin is going to assign the addresses specifically rather than letting the network autoconfig.

This is offset, however, due to the fact that IPv6 is a protocol which has been designed and formulated with specific technologies in mind... specifically, high bandwidth connections. As fiber optics, fast ethernet, and gigabit-copper become more common, total bandwidth will increase, and the relative increase in latency/traffic is offset by higher bandwith availability. Call it information inflation, if you will...

(specifically, in order to deal with 128 bit address routing tables) so, the latency and traffic usage will be offset by the reduced processor overhead needed to calculate the 'details' which are incorporated into the header (such as quality of service and such...). That is, the network engineers know that fiber is becoming more common, and this protocol was designed with forward-thinking concepts: high network bandwidth, very large numbers of nodes, dynamic network topologies, security and cryptology, etc. etc.

    Why should they renumber?

    If you have two companies who want to talk to each other you can do this:

    Company A internal network (private address)
    |
    Firewall A--Company A service B net
    |
    internet/other connection(e.g. vpn)
    |
    Firewall B--Company B service A net
    |
    Company B internal network (private address)

    Company A can only talk to hosts in Company B's service network for Company A. And vice versa.

    The _service_ networks could have private or public IPs, as long as they don't clash.

    When two companies agree to talk, they just agree on using service network addresses that don't clash. No need to renumber everything behind.

    In order to hook up their networks, Management needs help from people who know what they are doing? Good!

    If the firewalls fail, they can't talk. Good!

    If they haven't agreed to talk, then they can't talk. Good!

    The internal networks don't have full access to each other? That's the idea dude!

    Call me a BoFH, but where's the problem you and he are talking about?

    Private addresses can help create situations where things are more likely to fail closed rather than fail open.

    The reason for private networks is for privacy. You don't go around exposing your private nets to just anybody. Relationships between companies change. If companies merge, the pain of renumbering is minor when you look at the big picture.

    Just as a side note, the "really neat" security improvements you list are simply the IPSec stuff found in a standard IPv6 stack. These same features are available in any IPv4 stack with IPSec tacked on. The difference is that, in v6, IPSec is manadatory, and in v4, it's optional.

    It's actually 16 bits larger, or 65,536 times larger.

    But I can't let it go at that, because that's also a bit wrong.

    The top 3 bits of IPv6 addresses are a format prefix. It cuts the address space into 8 pieces. The top and bottom ones are used for things like multicast, link local and IPv4 mapped addresses. One of them is the place where allocations are happening today - the Agregatable Global Unicast space. So if we lop off the top 3 bits from the 16, we get that the current allocation space is 12 bits, or 4096 times larger than the IPv4 space.

  67. Diffserve/IntServe by germanbirdman · · Score: 2, Interesting

    I actually wrote a thesis about using IntServe/Diffserve for a video conferencing application across the internet.
    It is a while ago now and I have had other things on my mind, but basically what I found out is that on the internet there is no real need for QOS as bandwidth is increasing all the time, satellite links are reolaces by fiber (less latency and delay, and a lot more bandwidth), fiber is being replaced by "thicker" fibers, etc.
    Just to give you an idea of the amount of bandwidth available - only 2.9% of all fiber optic cables layed alongside powerlines, rail roads etc are actually lit. And those that are lit, thos in use for the internet only have a maximum use basically of 50%.
    Also, in order to give certain datastreams priorities over others, you need to track these, which adds processing delays and with networks where bandwidth is not a problem - why do this?

    Also, something often overlooked:
    In order to actually give packets priority over others and shape the traffic depending on priotities, you need to queue at least 200 packets it was discovered by some researchers, otherwise the queuing algorithms just do not have enough data to actually put into different queues. Think of it this way, if the queues are empty, then of course the data is sent to the top priority queue and you gain nothing.

    Basically, there are two concepts: Diffserve and Intserve.

    Intserve goes against the nature of the internet (in my opinion), as it uses RSVP to set up a quasi-static route through the internet, does the reservations, and then the flows have to be monitored. Keeping track of individual flows on the backbone routers? No way! And if the route changes, all the reservations have to be done again. Intserve (IPv6 has a Flow Label to facilitate this) has no place on the internet backbone in my opinion.
    Intserve is very useful though in an organisation, where you have control of the network, and to give certain flows priorities getting out of that bottleneck router to the internet and then let best effort scheduling do it's work.

    DiffServe on the other hand is viable in my opinion as this is hop per hop based. Diffserve works by marking packets and assigning it a traffic class.
    This is very useful when you have flatrate customers, and customers that have are willing to pay for bandwidth. Of course the routers could and may already mark traffic of those customers paying for bandwidth with a higher priority.

    Something which I really like about Diffserve is the ability to give packets a drop priority ("Hello you little nice router, If you really need to drop a packet, please drop this one").
    This could be very useful in the case of video over the internet where the network itself regulates the quality of the video. What I proposed in my thesis, was to have an algorithm that send the most important coefficients in a packet with a low drop priority, the next batch with a medium priority and the rest with a high one, and in addition to that also have the software on the other end report back some statistics so sending is also reduced.
    What this is allows is to have video not stop, but just instantly become of less quality if there are congestions.
    Speaking of congestions, they only exist till the packets they reach the backbone.
    And of course getting down from them again.

    What has my post got to do with IPv6? Well, IPv6 has a Flow Label and Traffic Class in the IP header which are for IntServe/DiffServe.
    Ipv6 facilitates IntServe/Diffserve, but does not really add anything new in this respect. It just makes it easier to process, because it is always at the same place whereas this info in an IPv4 packet could be at varying locations due to the variable length of an IPv4 header.
