Dropping from 4096QAM to 2048 or 1024 is a first world problem.

I used to think reliability was everything. Lately, customers whine about bandwidth constantly. If there is a several hour outage once or twice a year, they whine a little and then forget it. But speed is at the top of the hierarchy of needs, above things like food and sex. Actually I am adapting this from my approach to licensed links. I used to think every link had to be designed for 5 nines (while realizing that with climate change that probably got us 4 nines IRL). So if I couldn’t find an intermediate point, or use 6 ft dishes, I’d do things like use a 30 MHz channel width to get a little incremental system gain. Now I will go for the most capacity on every link, figuring more bandwidth 363 days a year was more important than 15 minutes of downtime 2 days a year. And if I don’t need all that capacity today, I’ll need it in the near future. The need for speed is not going away.

You could have 100 different upstreams but if they go across one fiber line, you are screwed.

Bigger pipes going to the same places (assuming the small pipes are sufficient to handle what you need) just isn't as good of a design. ----- Mike Hammett <http://www.ics-il.com/> Intelligent Computing Solutions <https://www.facebook.com/ICSIL> <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> <https://www.linkedin.com/company/intelligent-computing-solutions> <https://twitter.com/ICSIL> <http://www.midwest-ix.com/> Midwest Internet Exchange <https://www.facebook.com/mdwestix> <https://www.linkedin.com/company/midwest-internet-exchange> <https://twitter.com/mdwestix> <http://www.thebrotherswisp.com/> The Brothers WISP <https://www.facebook.com/thebrotherswisp> <https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg> _____ From: "Mark - Myakka Technologies" <[email protected] <mailto:[email protected]> > To: [email protected] <mailto:[email protected]> Sent: Wednesday, August 26, 2020 1:32:46 PM Subject: [AFMUG] Upstream Bandwidth Question We are starting to get close enough on upstream bandwidth, where I need to start thinking about getting some more. Currently we have two 10G ports going to two different data centers. With the internet connections, IX links and current hardware, I can pull about 8GB max from each port. Currently in peak times we pull a total of about 4-5 gbps on one line and about 3-4 gbps on the other. It is manageable now, until an upstream goes down during peak times. That has only happened once and it was a bit dicey. The question is which would be "better"? A. Upgrade the two pipes to 20/40/100G whatever is the standard now. Buy new hardware to handle the new speeds needed. B. Build out a 9 mile fiber run to a possible POP where I can possibly grab some dark fiber or at least another 10G and run to a possible 3rd data center. I personally like B, being I can push upgrading the other two links down the road. This is a rural area, but a state road, so the fiber install won't be cheap. However, I can possibly pick up 10-15 customers along the way with the possibility of getting more as things build out. Currently the two upstreams balance themselves out. I don't have any fancy code doing load balancing. If I add a third to the mix, I'm not sure how well they will balance out. Just trying to figure out pros and cons of each. -- Thanks, Mark mailto:[email protected] <mailto:[email protected]> Myakka Technologies, Inc. www.Myakka.com <http://www.Myakka.com> -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
