Interframe gap has no dependancy on station vector. The dependancy for CSMA/CD was bits on the wire and the alogorithm backed off until it was free to transmit. Are you talking about something else? -M< -M<

Well done. You're jumping to conclusions. As Jeroen mentioned, it could be just someone getting an /17 (with a /17 above reserved for expansion).

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<
