exp(M) (shoul've been exp(t)) is the growth of Internet. Any sane policy will have to account for it (and, no, just doing three levels is not enough, there should be a way to go into more levels if needed later). The idea of using "randomizing" sub-domain is to get people used to the idea of randomization in domain names. Then it can be moved into protocol or implementations. It also fixes the name collision and transparent introduction of multiple registries. There is no other way to satisfy N users when every one of them wants to be named "Itty Bitty Machines". --vadim

Well, that solution have a problem not present in vanilla DNS -- nameservers no longer correspond to administrative boundaries. And it does not do anything to fix the name collision problem. --vadim >From nanog-owner(a)merit.edu Mon Apr 22 19:26 PDT 1996 Return-Path: <nanog-owner(a)merit.edu> Received: from postman.ncube.com by butler.ncube.com (5.0/SMI-SVR4) id AA16645; Mon, 22 Apr 1996 19:26:03 +0800 Received: from titan.sprintlink.net by postman.ncube.com (4.1/SMI-4.1) id AA28280; Mon, 22 Apr 96 19:27:42 PDT Received: from merit.edu (merit.edu [35.1.1.42]) by titan.sprintlink.net (8.6.9/8.6.9) with ESMTP id WAA01557 for <avg(a)titan.sprintlink.net>; Mon, 22 Apr 1996 22:27:31 -0400 Received: (from daemon@localhost) by merit.edu (8.7.5/merit-2.0) id VAA29036 for nanog-outgoing; Mon, 22 Apr 1996 21:38:51 -0400 (EDT) Received: from chops.icp.net (chops.icp.net [199.0.55.71]) by merit.edu (8.7.5/merit-2.0) with ESMTP id VAA29030 for <nanog(a)merit.edu>; Mon, 22 Apr 1996 21:38:48 -0400 (EDT) Received: by chops.icp.net id <20637>; Mon, 22 Apr 1996 21:38:40 +0100 From: Sean Doran <smd(a)icp.net> To: pferguso(a)cisco.com, smd(a)icp.net Subject: Re: NAVYJOBS.COM Cc: john(a)interport.net, nanog(a)merit.edu Message-Id: <96Apr22.213840+0100_edt.20637+44(a)chops.icp.net> Date: Mon, 22 Apr 1996 21:38:31 +0100 Sender: owner-nanog(a)merit.edu Precedence: bulk Content-Type: text Content-Length: 2174 Status: R | Personally, I like the <eighty-subdomains>.BigCompany.COM. approach; | it just scales better. Less messy. Tastes great. Me too. However, there appears to be some counterpressure to move towards what I perceive as some kind of system which lacks any real hierarchy in the sense of domains. Perhaps instead of trying to "fix" the DNS by creating huge new bunches of things to the right of the last normally-seen dot, we should move towards something completely different. Maybe instead of: <whatever>.COM being considered as three tokens and being looked up as: ask a ROOT nameserver for COM NSes ask a COM nameserver for <whatever> NSes ask a <whatever> nameserver for appropriate info (all modulo caching) instead we treat it as (leaving out the '<' '>' stuff out of laziness): <w><h><a><t><e><v><e><r><.><c><o><m> and look up like this: ask a ROOT nameserver for M NSes ask a M nameserver for O NSes ... ask a <w> nameserver for appropriate info that will scale to a huge number of generally unformatted labels for things. This strikes me as a practical way of moving towards ".Earth" and ".Alt" and thousands of other "top-level-domains". Other than technical scalability, the other general design goal for any changes to the status quo wouuld have to be administrative scalability. As a too-easy example, in this model that's essentially making sure an overworked or evil delegator for $origin ever.com won't break the ability of people wanting $origin whatever.com or $origin never.com from going about obtaining those names. Perhaps some form of automagic registration scheme should be available to allow for others to initiate any rightwards growth of names unless they involve certain charaters (like '.', perhaps, so as not to overly confuse people who are used to foo.bar.com being under the administration of whoever is in charge of bar.com) Again, I worry about being wasteful of other people's time here; this could be a non-issue for operators big and small for all I know, so I'll drop back into read-only mode for a bit, and let smarter DNS people and folks more in the trenches talk it out (or ignore it).

The current problem with DNS is not load on root NSes (however, even a blind person can see how exponential growth at more-than Moore's law will get it to the point where you simply won't be able to find a box fast enough to run root NS). Those of us with longer memories remember times when 16Mb on AGSes was "more than enough for any foreseeable future". And, yes, followinmg your analogy, 99.999% of routers do not have to have more than 100 routes in them. Does it help a dozen of dying backbone boxes much? The current problem is increased name collisions. Which is, to say, a fundamental one. No matter how you jump you won't be able to decrease rate of name collisions w/o increasing depth of the tree. The only other remedy is to stop choosing natural abbreviations and start doing as AOL does with customer names. Which is, essentially, an inferior way to do exactly what i proposed to do. (And, BTW, there's life after 26 letters are done with; you can set moving "line in the sand" on who gets shorter names). But -- the idea that first level domains are sexy got to be stomped out before anything real can be done about DNS. New TLDs is merely moving the problem one level higher. It definitely cannot fix anything. --vadim PS. No, i don't call to "rename Internet".

Creating a problem to solve a problem is not a solution. Paul already said that a 16MB 486 can handle root DNS just fine. This does not bespeak of a problem requiring "renumbering" hundreds of thousands of domains. FURTHER, your "big win" is only a 1/26 lessening of load. If the problem is such that 1/26 is a "big win" I think it's not big enough to rename the Internet for. ... >What we should worry about is number of first-level >domains/number of hosts ratio. It is the same problem >as with routing. The solution is also the same -- No, it's not the same problem as routing. All routers with non-default rules need to know about all routes. The only possible analogy for that in DNS is root nameservers. These (as Paul pointed out in a previous post, since he runs F) are not saturated, and don't require that many resources. If you feel the growth of domain names is such that it will outstrip a 486 w/16MB soon, tell me when it will be a SIGNIFICANT problem. I.e. when will it outstrip a real machine (Sun, VAX, Alpha, SGI) with real memory (64MB? 128MB? 4G?) Remember, upgrading HUNDREDS of routers all running 45Mbps is a priority. Upgrading 8 boxes running BIND and doing it well is a much much much lower priority. >mnemonic can be used to distinguish between thousands of >nearly identical small businesses?) >--vadim >PS.

request to network operators
by Jeremy Porter 19 Apr '96

19 Apr '96

In keeping with my goal of providing the Nanog community with some numbers based in fact, that indicate paths toward sustainable Internet economics. Please note, all raw data I gather and my methods will be published, hopefully at May Nanog. This work is based on cost studies of resource utilizations in the various parts of the net. Some people may not agree with my conclusions or my methods, and I don't realistic hope to end the various debates on policy, but the calculations cannot be made without reasonable data that reflects todays Internet. I have traffic data comming from 3 of 5 of the major naps, and hope to get the last two on board soon. I need flap data, but it apears that the RA project has reasonable data to work from. Lastly I need information on router table utilization, speicifcly if you have Cisco routers at 3 or more of major exchanges, and basicly run "defaultless". Specificly I'm looking at processor and memory utilziation in Cisco routers with large numbers of views/paths. The magic command in this case would be: show ip bgp sum If for security reasons, you do not wish send the whole output, I would be happy with the first summary part, as I don't need the peer information. The Cisco firmware version would be helpful, but not required. It would be nice to have a MAE-East and MAE-West snapshot, but I'm not terribly picky, and realize that you will be taking time out of your schedule for this. Anyone that sends me a snapshot of 2 or more routers, I buy lunch for at Nanog.

Northwest Internet eXchange (NIX) operational!
by Eric Kozowski 19 Apr '96

19 Apr '96

The NIX is now initially operational! IXA and NWNexus are currently exchanging traffic. Structured should be connected next week (if I get time to hook the circuit up). According to Ed @ NWNexus, traffic is running between 25kbps to 65kbps, with only the two of them connected. For those of you not familiar w/ NIX, take a look at: http://www.structured.net/nix Eric PS - Thanks to Ed and Nikos for getting things rolling while I was busy w/ other things. -- Eric Kozowski Structured Network Systems, Inc. kozowski(a)structured.net Better, Cheaper, Faster -- pick any two.

Flap dampening works on most routers- just have to be aware of what the effects are, particularly with multiple BGP Peers. You have to decide whether to dampen outbound and/ or inbound, and if short duration events like temporary recalculations of the IGP are considered a "flap".
