Can someone explain to me how FTTH providers typically enforce speed tiers?
Is this a function built into the OLT? Router? Switch? A dedicated QoE device? Is it a simple port speed type of rate limit? Are there buffers to queue excess traffic? Any kind of per-flow management, deep packet inspection, prioritization, anything like that? I'm having a hard time wrapping my head around how traffic shaping would work at multigigabit speeds, and whether that level of sophistication is needed when you have that much bandwidth available. To be honest, I also don't understand how consumers decide that 1 Gbps symmetric isn't fast enough for their household and they need 2, 5 or 8 Gbps. It almost seems like you could just run the network wide open and charge people what they're willing to pay, except people want to run speedtests and see that they're "getting what they pay for".
