Drew, The YouTube channel Asianometry has some good insights into the underlying supply chain problems: https://youtu.be/YJrOuBkYCMQ Deposits that the issue isn’t with leading as chips, as you might think, but with so-called “trailing edge“ chips: microprocessors and support circuits that make up the bulk of electronic components, including routers and switches. Asianometry points out that trailing edge components account for 50% of sales in the chip market, and given their much lower price of just a few dollars each, they represent many times as many units. This makes them a much larger factor in the supply chain problem. Everything is finally keyed to “just in time“ manufacturing, with very little component supply in the pipelines. When Covid hit, those pipelines dried up and everything collapsed. -mel beckman On Jul 16, 2022, at 4:19 PM, Forrest Christian (List Account) <lists@packetflux.com> wrote:  The underlying problem is silicon Fab capacity.

If you don't have components for your product, a new order for components will take a year to arrive just because the factories that turn raw silicon wafers into computer chips are backlogged 12 to 18 months. Note that all of the existing factories are running around the clock, and although additional facilities are being built it takes time for them to be completed. I'm also assuming that there has been some question about whether this is short term or long term demand which would influence whether you spend a billion dollars or more building a new fab.

If you look at the NANOG archives, this was discussed just a month or so ago, somewhere in the middle of the Juniper MX204 EOL discussion, IIRC. I’ve been seeing a number of analysts with models which show a brief reprieve in 2023 then a regression (i.e. back to where we are today, or even worse) from there out for another 4-5yrs, and no-one’s putting much credibility in models much past 5yrs right now. Which is good, because some of those models say we’re screwed for the rest of our lifetimes. I don’t know the details of why, although I do recall that some of it is based on queueing theory, so the ultra-short hyper-efficient JIT pipelines our society has spent the last 50yrs building likely play a part. FWIW, I saw something about vehicle manufacturing where a factory rep was proudly proclaiming that they’d optimized the JIT process to where they needed some specific part – and engine, I think? – delivered from the part manufacturer twice daily... seemingly completely oblivious to the supply-chain risks involved. -Adam From: NANOG <nanog-bounces+athompson=merlin.mb.ca@nanog.org> On Behalf Of Drew Weaver Sent: July 18, 2022 8:51 AM To: 'Mel Beckman' <mel@beckman.org>; 'Forrest Christian (List Account)' <lists@packetflux.com> Cc: 'nanog list' <nanog@nanog.org> Subject: RE: Papers/analysis on network equipment pricing since pandemic/banning foreign competition Okay so I suppose how many years are we allocating mentally for them to take any action?
