Obvious caveats: GPON networks are often vendor locked. This means you cannot just buy any random SFP ONU and expect it work. Even if you do get it to work, no ISP will offer you a…

Bulk transfers aren’t that being interesting from a networking perspective. You gonna have a bad time if you optimize only for the best case scenario. Even using IMIX is a low bar.…

Interrupt moderation only gives a modest improvement, as can be seen from the benchmarking done by Intel. Intel would also not have gone through the effort to develop DPDK if all y…

TCP/IP offload isn’t the issue. The core problem is that the Linux kernel uses interrupts for handling packets. This limits Linux networking performance in terms of packets per sec…

Google fiber had very specific requirements for their build-out. Not all locations were able or equipped to meet those demands. Other than that, what specific regulation are you re…

Does not help. Tor is heavily throttled and blocked.

Oh, sweet summer child, do you think you can escape the NSA? :) More seriously, private ISPs in a (local) government owned open access network does not mean the (local) government …

What could possibly go right? Read the comment about NZ. Or refer to Sweden.

There is only so much wireless spectrum. Multiple companies are allowed to lay fiver. It’s not regulation that prevents overbuilding but economics.

> An ISP grows a large user base by doing aggressive price competition, then starts shaking down services, rate limiting their traffic if they don't pay up. Yeah, we’ve already see…

Sound like you are probably just overpaying for bandwidth and/or DDoS protection.

BGP doesn’t work that way. You cannot control who your prefix is announced to, unless you control all the paths on the Internet.

Only for outbound traffic, tho. For eyeball networks and other stub networks this is mostly fine.

I’m interested to hear how you 1) block 2 Tbps of attack traffic 2) save $500k per month in bandwidth charges since blocking at the border means you have to pay for the incoming ba…

Because your ISP is not keen on paying for third parties transiting their network.

The switch does not care what kind of optics you use. You can use a $50 switch is you like. The 200 km optics, however, cost about a grand each.

Until recently NBN fiber connections only came with 2 Mbps of bandwidth. Any usage over that was billed at $8 per Mbps to the ISP. In other words, an ISP customer taking full advan…

The Australian NBN would also have sucked a lot less if the government hadn’t sneaked in usage fees on the network. It is, or at least was, insanely expensive to use the Australian…

Everything you wanted to know about optical networking - but were afraid to ask https://www.nanog.org/news-stories/nanog-tv/top-talks/tutori... You can check pricing on any of the …

I think you are overstating the problems of relying on IP transit somewhat. A typical content creator is unlikely to have enough demand for their videos to congest IP transit links…

You are very, very mistaken. Only 28% of Alexa top 1000 sites support IPv6. Very, very few, if any, consumers of commercial ISPs have only IPv6 access.

The Internet does not work without IPv4. It’s either CGNAT or ponying up $60 per IPv4 address.

Time to build a wireless link to your friend :)

I can see this being used for backhaul in remote areas. There’s a bit of a risk for adverse selection, as anybody willing to spend $500 per month on this is going to want to get th…

This is a straw man. Physical path redundancy for backhaul and/or feeders does not require two of everything, merely that you close the loop.
