Uh.... I think I'm missing something here. First, Internet2 is (was?) a research-only network. It's not (supposed to be) a place for pr0n and other commercial use.
You speak of standards. The Internet, as we see it, is just a collection of heterogenious networks in a homogeneous naming space (well, mostly--a discussion of NAT is beyond the scope of this comment). You want to move to I2? Fine. Go enroll as student or faculty at one of 180 research institutions. Just don't go there for much Quake use :-)
You also take a look at kermit. Kermit was not an Internet protocol per se, but was a terminal-terminal download protocol that assumes unreliable network streams. Yes, that means certain instances of kermit-over-IP existed, but it doesn't mean that kermit was necessarily an Internet application-level protocol, where most transfer tools assume a TCP-level (or equivalent) functionality, leaving error detection and correction (among other things) to the lower-level protocols, and it dealing more with the application-specific information.
As for benchmarking /. code, I really don't see the difference of its code running on I2, Internet, or my home LAN; provided that the host is mated to a decent backbone, its performance would be more dependent upon load/system configuration than the underlying network itself. I2, with its much smaller user base and a similar backbone, consequently has much lower load, so it should perform better.
Besides, if you wanted to compare/contrast I2 to Internet, you'd probably do a network traffic analysis (peak bandwith, peak latency, multiplexing capabilities, etc), which would be a function of the routers than anything else.

Priority Packets (Score:3)
I-2 is researching what it calls "quality of service," some way to guarantee seamless delivery of priority transmissions. A collaborative medical procedure, for instance, should not be interrupted by e-mail traffic. One thought is to create a premium service, where critical data would be tagged so that routers would pass it through first, much the way railroads clear the tracks for express trains.
The way the article makes it sound, there will be a purely technical reasoning behind which packets will be given a priority. Bzzzz, wrong answer folks. What is being sold to corporate IT managers out there (based on some IPv6 seminars I've been to) is that you'll be able to buy higher priority for your packets.
Stop and really think about this. You're an ISP that can assign a different priority to packets going to and from your various customers. Are you really going to ignore the billing potential of selling higher packet priority to different folks? For that matter, as the demand goes up for higher packet priority, so does the cost.
There are some truly frightening scenarios that can come to play here with the standard as it is presently being presented. What we're really looking at here is that live medical procedure waiting at the router for a CEO's E-Mail to get through.

If it is kept closed and limited to universities it will become purely an academic entity for research, development and communication and a test bed for future technology.
The problem which might happen in the latter possibility is the private sponsors, Worldcom, Qwest, others, may eventually want to see some return for their investment translated into profitable products. If I2 does not produce marketable products or technology which can add to the companies' bottom line, there is again, a possibility that stock holders, board directors or company officers may decide to withdraw funding.
Finally, a portion of I2 is financed by taxpayer money. As with nearly every federal program, there is always the possibility of Congress cutting or eliminating funding in the future jeopardizing I2's existance. See Super Collider for further reference.

Which is, in fact, a part of the problem, but not when separated from the whole view, namely urban development as an entirety. Take a step back to Portland, to San Diego, to Toronto. All of these cities have large urban populations and busy downtown cores, with major potential for traffic...but the cities in question have alleviated the problems by favoring inmprovements to transit rather than road infrastructure. portland took things one step further, drawing on traffic calming projects in germany (they know cars). What followed was a a series of laws that eliminated free parking for company employees, and large subsidies for transit and carpooling (either monetary, or physical allowances. In all three cities, one can find car lanes that are only for use by cars with three or more passengers, or buses).
What followed was a "the establishment of an urban growth boundary adopted in 1980, middle-class neighborhoods continue to grow and thrive close to the downtown instead of engaging in a suburban exodus, while more distant, exurban communities remain undeveloped, leaving the people there in therir pastoral splendour...this contrasts sharply with cities such as Detroit where 30% of the downtown core remains empty and the only people who live there are either the very rich who inhabit 'fortress' areas which are access controlled and patrolled by private police, or the very poor who live in run down areas with a decayed infrastructure...the stabilizing (emphasis mine) middle-class having fled to the suburbs long ago." [Namir Khan, Healthy Cities Report]
The pattern is cyclical...roads --> people --> traffic --> roads --> people...you can add elements to the cycle ad infinitum, as guaranteed by the butterfly effect. Pointedly, the statement worth making is not "roads cause cars", but instead "roads do not cause less cars, only more traffic".
It's interesting to think about the middle-class as the stabilizing factor in urban development (and by extension, traffic use). If we were to categorize a hierarchy of internet users, what would be the defining parameter? In the urban case, it's clearly money...on the web, i would argue that the class system of internet usage revolves around bandwidth speed (the obvious conclusion), but rather the wealth of knowledge and information in transfer. The premium is web space, just as in cities the premium is land. The purchasing power is in the value of your information...large multinational companies constitute wealthy, gated communities with private intranet policing and limited access, whereas the 'poor' netizens spend their time chained to useless IRC events and porn surfing. in this case, the stabilizing factor happens to be people with legitimate interests in technology and even a hand in the process.

The closest comparison of a system we can observe in relation to the internet is an ecosystem. In either case, it grows, it shrinks, it responds to change, it is populated (an ecosystem by organisms, the net by information), whereby only the fittest of beings/data survives progress, and it is abused by humans. The only difference is that we created it.
Here then are the things to keep in mind when making an analysis of the net: (excerpts taken from The Ecosphere, by Barry Commoner)
The First Law of Ecology: Everything is Connected to Something Else
No such thing as inside-outside influence in the internet. There is only one set of 'organisms', one collective of criteria that affect the net, and it's anything that is wired. Bloat or not, it will affect our network. "The dynamic behaviour of a cybernetic system-for example, the frequency of its natural ocsillations, the speed with which it responds to external changes, and its over-all rate of operation-depends on the relative rates of its constituent steps." Like Baka_Boy was saying, when you get off the freeway, if the local roads suck, you're still screwed.
The Second Law of Ecology: Everything Must Go Somewhere
This is where the principle fails. On the net, you find dead ends. On the net, you find concepts and organisms that are ephemeral in every sense of the word. On the net, the life or death of an idea is just a matter of energy.
The Third Law of Ecology: Nature knows Best
The premise being that by whatever means possible, the course of nature has perfected the stability of organic chemicals to the point where anything man-made should be treated with caution at the very least (this is why every single one of you has minute amounts of ScotchGard in your bloodstream right now. So far, no ill effects have been found, but 3M has stopped making the stuff recently, despite the fact that the industry is worth several billion dollars. Food for thought: if they acknowledge the possibility of adverse effects now, they are not criminally responsible for them by US law. Makes you wonder how much damage is possible, that would make the loss of billions preferable to compensation. For a related comment, see this [slashdot.org] post of mine). Unfortunately, there isn't a lot we can use here, because the internet is a creation of man to begin with. The most we can do is look for ways to turn linear, destructive patterns of information into cyclical events. OOP anybody?

I'm not sure what was the I2-UIUC server pipe, but if you trace the traffic to from Stanford to UIUC and IIT, the numbers that are returned show equivalent times from Stanford to the UIUC I2 router and from Stanford to the ultimate IIT server that hosted our services.

Moving past the electron autobahn (Score:3)
More than 30 years ago, an author by the name of Helen Leavitt argued that expanding roads led to MORE traffic, not less. The argument was fairly simple...sure, you may get a little more breathing room for a while, but that doesn't address the real problem: too many people are driving on this road. Having more space leads to, well, more people driving on the road. (Leavitt, Superhighway-Superhoax. Must reading for the next generation of civil engineers...some of the fluffier tree-hugging ones have taken the cause to heart at this [foe.org] site).
If you stop to think about it, it makes a lot of sense.
Now i'm going to continue my line of thought, asuming you follow with the whole "more road = more road rage" theorem. (For those of you who still aren't convinced, either you're an old-school civil engineer in which case there's no hope for you, or you're not, in which case you'll be swayed by case studies like the city of Portland. In the 60-70s, Portland was having huge traffic problems. to solve the situation, they demolished a downtown freeway.) the question is: does the same logic apply to the internet?
Obviously, with a larger backbone you're going to see both a decrease in transfer time and an increase in usage. But is the decrease a temporary effect? I have a lot of friends who have seen their broadband service deteriorate to the point where they can get their kicks faster on a free isp. I'm sure you do too. Coincidence? Hardly...
The key difference between real traffic and internet traffic is that physical space is not at a premium. In the real world, land is the bottleneck factor. On the Web, the difference between 5 lanes and 50 lanes is also real, just not in the same way it is in your suburb. What does that mean? There is a greater allowance for 'lane width' patches on the Net...this still doesn't change the fact that to solve information transfer problems, we need to come up with better ways to shift packets, with better cars if you will, rather than expanding the avenues for that data infinitely (a solution doomed to failure because there will always be more data than road. How many of you thought your X-gigabyte hard drve was enough space, only to find it filled yet again).
What are these solutions? I don't know, i'm (almost) an electrical engineer not a magician...try sifting through Jane Jacobs or Peter Calthorpe or some other engineering conceptualists for answers...it's more likely that a new wave of net design theorists will need to stpep forward and shed some light on the rampant growth, kind of like hacking through jungle foliage with a machete so we can actually aget somewhere.

That said, there is a noticeable difference in the download speeds that you will see between I2 sites and sites on the commercial Internet, even in your dorm room. You mentioned in another post that the school's link to I2 is generally under 50% utilization and that the commercial link is often saturated. The campus LAN is rarely saturated, so the bottleneck when accessing commercial sites is usually at connection to the outside world (it was a 12Mbps link the last time I checked, but as I already mentioned, it's often completely saturated). So what I'm saying is that I2 isn't for the MP3 and porn downloading pleasure of students, but it does speed it up for a lot of them.

How do those of us lucky enough to be at one of the I2 sites take advantage of this network, be it for accessing a superfast linux mirror or for any of the other (relatively few) services running on the network?

Re:Moving past the electron autobahn (Score:1)
What is happening is that the cost (in both terms of time and money)of moving a packet is being reduced and as any economist can tell you all uses for that packet which are at least as valuable as the cost to transmit the packet will be used. The problem with this is that as the cost of moving a packet tends toward zero the value of the average packet will also tend toward zero.
When the internet is expensive it will only be used for its most valuable uses. Right now internet2 is very expensive and therefore is only used for valuable purposes such as scientific research. When this technology becomes cheap and generally avaliable it will be used for the most worthless things that you can imagine.

We may actually start to see this happen as mobile net access becomes more common. Since there's a definate limit to what kinds of information will be useful (or usable) to someone working on a 300 pixes square screen and small keypad, moving the sites that those people are most likely to use onto a seperate, but linked, "cache" network (think Akamai on a different protocol or port) could help ease the burden on the rest of the network.

Sorry, not to be pedantic, but what you just described is 5 529mbps, far in excess of what you just described with your DSL saturation issue.
I think the main issue with your "inability" to saturate your DSL is an issue of bottlenecks; with an analogue modem connection, your modem is the bottleneck, with your DSL, some upstream provider somewhere is.

vBNS, the other Internet2 backbone, also has a similar 4-router configuration, though in this case the routers are all core type routers, serving Chicago, San Francisco, Maryland, etc.
Both backbone teams seem to be in 'experiment with IPv6' mode, no doubt due to the learning curve and scarcity of routers that actually support IPv6.
Re: IPv6 migration/co-existence (Score:3)
There's been lots of work on migration of IPv4 to IPv6 - or more correctly, coexistence, since it's quite possible IPv4 will never disappeare completely, just like DOS... The details are fairly complex, but there are various tunnelling schemes (some including automatic tunnel setup as required) as well as protocol translators that let an IPv6 domain talk to IPv4 land via (you guessed it) something like a NAT.
In time, hopefully, the IPv6 domains will get larger and larger and gateway directly to each other - the 6bone, which is an international IPv6 network, is currently a mixture of tunnels over IPv4, and some 'real' links that are native IPv6. There are even ISPs that have rolled out native IPv6 service, e.g. NTT is one that has done quite a lot in this area.
IPv6 is particularly useful to Asia and other non-US/European regions, which didn't get much IPv4 address allocation and now really need the address space. It's also important for the massive mobile Internet roll-outs that are happening over the next few years. Just as soon as Microsoft, Cisco and others start shipping IPv6 as standard (quite soon now) it will have a chance of taking over, though it will take anywhere from 5-10 years IMO.

Re:We need to keep this one "clean" (Score:2)
That begs the question (though it has also come up in other discussion of network theory and design): Where do we draw the line between reliability and performance of a network, and the privacy of its users?
In a completely anonymous system, no one can be tracked down to persecute them, whether they are a harmless /.'er or an international terrorist or script kiddie. On the other hand, a network with a unique ID for every device and individual lets spammers and kiddie porn peddlers get blocked, but also gives the gov't, or anti-abortion activists, or your carzy ex, find out who and where you are.
So, what do we do? Continue with the awkward practice of a partially anonymous network and optional, somewhat reliable authentication? Or do we move further towards one of the other ends of the spectrum?

I think, though, that we've already begun to see some of the same "suburban exodus" you speak of, though, in the form of AOL, MSN, et. al. -- they're a kinder, gentler, easier-to-use Internet, without all the headaches of the real thing. My grandparents, family friends, etc., won't even think about using a "real" ISP, and are more than willing to take the hit in performance, cost, and availability of information that the mega-services require.
So, dear /.'ers, a question: Do we want to keep the Net together, (impose growth boundaries, etc.) or should we allow those who lean that way to leave for the "'burbs," and deal with the leaner, meaner Net they leave behind?
