sprint passes uu?
I don't know if anyone cares or is keeping track, but it seems that Sprint has now passed UU in number of customer routes (or at least, routes sent to peers). x.x.x.x 4 1239 2396636 438162 61442761 0 0 9w3d 47637 x.x.x.x 4 701 3768775 499186 61442761 0 0 1w5d 45410 Looks like UU routes have been steadily falling, dunno if they aggregated (hah!) or just lost customers due to, well, you know. But by the metrics people/reporters have been using to declare UU "half the internet", it looks like they're now #2. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)

Well.. yeah.. but my hypothetical 64 /8's are twice address space than your hypothetical 2,097,152 /24's. About the only conclusion that you can *safely* draw is that Sprint has a more complicated network than UU does. Now *hopefully*, they have more customers too, or the Sprint backbone engineers will have to carry a much higher complexity/customer ratio, which means when the senior engineers finally snap under the pressure, we'll get junior engineers making weird work-arounds that will just complicate things 5 years down the road. Oh wait.. that already happened at most carriers, didn't it? That's where we got the CURRENT crop of senior engineers.. ;) -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech

Of course, but it's still a metric I see getting tossed about.

Or that they peer with even less people than UU does, and force people to buy transit. But it makes an interesting point about that mythical "50% of the internet" people talk about with regards to Worldcom, a lot of it is the same routes, and the amount of single homed customers is a lot less. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)

Perhaps flow data for _701_x$ and _1239_y$ (some overlap between <x> and <y>) would be more accurate.

The interesting part of that to me is that the total number of prefixes in a full feed is in the low 100,000 range, so this still represents a very large percentage of the entire prefix pie. Bri On Tue, 15 Oct 2002, Richard A Steenbergen wrote:

It's hard to know how large a percentage though without knowing how many Sprint customers are also UU customers. i.e. The combination of Sprint and UU customer routes could still be just 47637 prefixes, though I'm sure it's somewhere between that and 47637+45410. It's certainly not 47637+45410, which would falsely suggest that together Sprint and UU have roughly 80% of the internet as customers. ---------------------------------------------------------------------- Jon Lewis *jlewis@lewis.org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

Roughly 34% of the announced UUNET routes are announced by Sprint also. But as others have indicated, this doesn't mean that much on it's own. It just means they announce a lot of prefixes, and a big chunk of it both are announcing. /nco

Well, just by checking the "big" providers off the top of my head, I come up with: ASN Routes Common Name ---- ------ ----------- 1239 47711 Sprint 701 45429 UU 3561 23205 CW 7018 23154 AT&T 1 20231 BBN/Genuity 209 17082 Qwest 3356 12587 Level 3 3549 12175 GBLX 6453 10403 Teleglobe 2914 8791 Verio 6461 8089 MFN/AboveNet 4200 7506 Aleron/Agis 1299 6773 Telia 5511 4261 OpenTransit 4637 4066 Reach 16631 2067 Cogent 2828 1842 XO 4006 1727 NetRail/Cogent ----- 256984 Which of course ignores many dozens of 1-2k route providers. Now, of course number of routes has absolutily nothing to do with amount of traffic (ex: AOL, which anounces 400 some routes (and a lot of those are RoadRunner) but is one of if not the single the most important sink of traffic in the world), but it's interesting nevertheless. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)
UUNET isn't just AS 701-- it also includes 702, 703, and a large set of other ASes around the globe. ...and number of announcements isn't a particularly useful yardstick for measuring the percentage of the Internet any given entity "operates". - jsb On Tue, 15 Oct 2002, Richard A Steenbergen wrote:

702 and 703 routes were included in that number. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)
