Data Center QoS equipment breaking http 1.1?
by up＠3.am 01 Aug '09

01 Aug '09

Sorry if this is a little OT, but we're seeing a serious problem and was wondering if it is what I think it is. In short: I have been moving services off of our servers in a data center onto a server at eSecuredata, who rents dedicated servers. The idea is to lower costs and eliminate having to deal with hardware. The advertise "unmetered bandwidth", but mention QoS measure to control "bandwidth hogs". One of my customers, whose site I just moved from a unique IP virtual host on my old server onto an Apache NameVirtualHost on the new one, worked fine at first. Then today, they started complaining about getting one of our home pages. I figured DNS or web caching issues, until I started seeing it for myself. It was no caching issue, it was NameVirtualHost breaking. I poured over my configs (I've done this config countless times), and saw this in the apache docs: http://httpd.apache.org/docs/2.2/vhosts/name-based.html " Some operating systems and network equipment implement bandwidth management techniques that cannot differentiate between hosts unless they are on separate IP addresses." So, I installed lynx on the server, and sure enough, it worked perfectly fine there, just not from anywhere outside eSecuredata's network that I could see. Can anyone shed any light on this particular practice, of this company in particular? thanks James Smallacombe PlantageNet, Inc.

XO - a Tier 1 or not?
by Charles Mills 01 Aug '09

01 Aug '09

Trying to sort through the marketecture and salesman speak and get a definitive answer. I figure the NANOGers would be able to give me some input. Is XO Communications a Tier 1 ISP? I'd say no based on all research and googling that I've done but they seem to meet some of the criteria (some != all and therefore not Tier 1). Any help here? Thanks as always. Chuck

Ahoy, SLA boffins!
by Bill Woodcock 30 Jul '09

30 Jul '09

So I've embarked on the no-doubt-futile task of trying to interpret SLAs as empirically-verifiable technical specifications, rather than as marketing blather. And there's something that I'm finding particularly puzzling: In most SLAs, there seem to be two separate guarantees proffered: one concerning "network availability" and one concerning "packet loss." Now, if I were to put my engineer hat on, and try to _imagine_ what the difference might be, I might imagine "network availability" to have something to do with layer-2 link status being presented as "up," while packet loss would be the percentage of packets dropped. But when I actually read SLAs, "network availability" is generally defined as the portion of the month that the path from the customer's local loop to the transit or peering routers was "available" to transmit packets. Packet loss, on the other hand, is generally defined as the portion of packets which are lost while crossing that exact same piece of network. Now, what am I missing here? Is this one of those Heisenberg things, where "network availability" is the time the network _could have_ delivered a packet _when you weren't actually doing so_, while "packet loss" is the time the network _couldn't_ deliver a packet when you _were_ actually doing so? Is "network availability" inherently unmeasurable on a network that's less than 100% utilized? Am I over-thinking this? Seriously, though, I know there are people who don't consider SLAs to be fantasy-fiction, and some of them must not be innumerate, and some subset of those must be on NANOG, and the intersection set might be equal to or greater than one, right? Can anybody explain this to me in a way I can translate into code, while still taking myself seriously? -Bill

Subnet Size for BGP peers.
by Jim Wininger 30 Jul '09

30 Jul '09

I have a question about the subnet size for BGP peers. Typically when we turn up a new BGP customer we turn them up on a /29 or a /30. That seems to be the "norm". We connect to many of our BGP peers with ethernet. It would be a simple matter to allocate a /24 for connectivity to the customer on a shared link. This would help save on some address space. My question is, is this in general good or bad idea? Have others been down this path and found that it was a bad idea? I can see some of the pothols on this path (BGP session hijacking, incorrectly configured customer routers etc). These issues could be at least partially mitigated. Are there larger issues when doing something like this or is it a practical idea? -- Jim Wininger -- Jim Wininger jbotctc(a)gmail.com

caches for peer-to-peer trafic
by Murtaza 30 Jul '09

30 Jul '09

Hey guys, I wanted to ask that if ISPs use any kind of caching system for peer-to-peer traffic? It seems to be difficult thing to do, though there is some research going on (including me). However, I wanted to ask about the practices being used by ISPs and I suppose this is the best audience to ask such a question. Thanks and regards, Ghulam Murtaza PhD Student, Lahore University of Management Sciences
