Depending upon how many around the world non native tunnels are being utilized. Early on the RIPE folks warned me about tunnels. They were right. -M<

Portable datacenter coolers?
by Mike Lyon 21 Dec '05

21 Dec '05

Anyone know of any places in the silicon valley area that lease or rent those portable datacenter coolers? You know, those ones that stand about 5 feet high, are usually blue in color and are on wheels? The ones you are suppose to have on hand in case your main cooling system takes a dump on you? Yeah, those. Anyone have any idea where I could get my hands on one fairly quickly? I am in Santa Clara. Thanks, Mike

RE: Two Tiered Internet
by Hannigan, Martin 19 Dec '05

> What I'm interested in is how the two service > providers will build a two tiered Internet. The PSTN is tiered both in architecture and operation. Switching hiearchies and a seperate SS7 network which is basically a billing network. I think the thought is service levels vs. congestion control. For example, CO's have call overflow mechanisms to tandem switch points which basically seek out excess capacity and use it as overflow for call termination if and when possible. I could see an internet hiearchy where preferred traffic was switch onto hicap overflow links with controlled congestion and other traffic, non premium traffic, "got a fast busy". -M<

RE: The Qos PipeDream [Was: RE: Two Tiered Internet]

Hi Benson, Okay -- forget about banks, forget about other comparative analogies -- let's talk about the Internet. I think Bill Manning hit on it a couple of days ago; Bill said something about the Internet being about best effort and QoS should be (various) levels of 'better-than-best effort' -- and anything less that best effort is _not_ the Internet. I completely agree with this, and I would also add that anything less than best effort is not a QoS frob, it is penalization, no matter what you want to call, and is a Bad Thing (tm). I really don't want to get into a debate on service-level semantics (e.g. WRED, etc.) but I think most reasonable people can understand what I'm trying to illustrate. This thread has gone one far enough as it stands. :-) I think that the knobs are already 'out there' for service providers, etc. to create real 'services', but to create arbitrary services just to protect one's walled garden, and/or to generate revenue (while also penalizing some customers) is something that the market will have to sort out. It always does. Vote with your dollar$. Cheers, - ferg ps. Having looked at QoS issues from the inside-out, outside-in, and various other persepctives, I do know a thing or two about it. :-) -- "Schliesser, Benson" <bensons(a)savvis.net> wrote: Randy- I don't think your bank analogy is very strong, but never mind that. I agree with what you're saying in principle, that if a user/customer buys bit delivery at a fixed rate then we should deliver it. But as ISPs we don't sell this. As a network operator, I do sell various kinds of point-to-point connections with fixed/guaranteed rates. But when I sell "Internet", or L3VPN, etc., I'm selling end-to-end packet-switched full-mesh connectivity. In this service, not all endpoints are equal and traffic patterns are not fixed. I.e., the service is flexible. "QoS" is about giving the customer control over what/how traffic gets treated/dropped. It's not false advertising. That said, if QoS controls are used to enforce the provider's preferences and not the customers' then I might agree with the false advertising label. If the result is to have anti-competitive effects then I might have some harsher labels for it, too. Cheers, -Benson [snip] -- "Fergie", a.k.a.

NAT Configuration for Dual WAN Router
by Joe Johnson 18 Dec '05

18 Dec '05

I've been trying over and over to figure this one out, but I'm just hitting the end of my wits. We have a remote office that can only get 768Kbps DSL, which they've not totally maxed out. So management's solution now is to buy a second DSL line, but they won't let me buy a dual WAN router (in case they add a 3rd DSL line). I've found some great articles on how to get the interfaces working with 2 default gateways (I used this: http://www.linuxquestions.org/linux/answers/Networking/Spanning_Multiple_DSL s) and that is all running fine. It alternates every few minutes which WAN port is used when I traceroute yahoo.com (which is fine) and everything is connecting fine from the router. However, I can't figure out how to get NAT running on the server for the 2 WAN ports for clients inside the LAN. I can NAT to 1 DSL, but that is useless. What I am looking for is a tutorial in how to do this or a pointer to someone who can help. Anyone know of a resource for this? Joe Johnson joe(a)sendjoeanemail.com
