Re: Alien Waves

My point was that the technology has little to do with the operational success of the service. Spectrum controllers better enabling providers to get out of their own way in selling spectrum did not actually enable the providers* to get out of their own way in selling spectrum. It *should* be easier than it used to be, but it isn't, and the problem is not really technical, but a question of 1) not having full-throated commitment to wanting to sell spectrum and 2) not having the talent to support it, which is really just a function of #1. *Speaking specifically about the very largest CLEC wavelength providers in North America On Sun, May 12, 2024 at 6:34 PM Mark Tinka <mark(a)tinka.africa> wrote: > > > On 5/13/24 00:11, Dave Cohen wrote: > > Mark, > > Many/all of these points are fair.

When something invariably breaks at 3 AM and the third shift Tier I NOC tech who hasn’t read the service playbook says “I don’t see any errors on your transponder, sorry, it’s not on our end” because they’re not aware that they actually don’t have access to the transponder and need to start looking elsewhere, that’s the sort of thing that creates systemic challenges for users regardless of whether the light is being shot across a Ciena 6500 or a Dave’s Box-o’-Lasers 1000. > > > I think you are contradicting yourself a bit, unless I misunderstand your > point. > > Legacy vendors who have spectrum controllers have made this concern less > of an issue.

Whitebox Routers Beyond the Datasheet
by Mike Hammett 12 May '24

12 May '24

I'm looking at the suitability of whitebox routers for high through, low port count, fast BGP performance applications. Power efficiency is important as well. What I've kind of come down to (based on little more than spec sheets) are the EdgeCore AGR400 and the UfiSpace S9600-30DX. They can both accommodate at least three directions of 400G for linking to other parts of my network and then have enough 100G or slower ports to connect to transit, peers, and customers as appropriate. Any other suggestions for platforms similar to those would be appreciated. They both appear to carry buffers large enough to accommodate buffering differences in port capacities, which is an issue I've seen with boxes more targeted to cloud\datacenter switching. What isn't in the spec sheets is BGP-related information. They don't mention how many routes they can hold, just that they have additional TCAM to handle more routes and features. That's wonderful and all, but does it take it from 64k routes to 512k routes, or does it take it from 256k routes up to the millions of routes? Also, BGP convergence isn't listed (nor do I rarely ever see it talked about in such sheets). I know that software-based routers can now load a full table in 30 seconds or less. I know that getting the FIB updated takes a little bit longer. I know that withdrawing a route takes a little bit longer. However, often, that performance is CPU-based. An underpowered CPU may take a minute or more to load that table and may take minutes to handle route churn. Can anyone speak to these routers (or routers like these) ability to handle modern route table activity? My deployment locations and philosophies simply won't have me in an environment where I need the density of dozens of 400G\100G ports. That the routers that seem to be more marketed to the use case are designed for. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

VDSL >2 Pair Bonding Modems
by Mike Hammett 12 May '24

12 May '24

I recently figured out that my Calix E7s can bond more than 2 pair of VDSL lines. However, none of my modem vendors seem to support more than 2 pair. What modem platforms are people using in this scenario? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Anyone that can help with AS10796 willing/able to contact me off-list ? I also have a message posted on outages. tl;dr: IPv6 issues since ~ 4:30a EDT. Checked from ATLAS probes and they fail as well so I don’t think it’s just me. Thanks.
