For Zhone and Adtran, it's built into the OLT platform. GPON and its derivatives have essentially protocol-level bandwidth allocation for burst, constant, guaranteed, etc. You could have 100 VLANs all with different QOS levels, guarantees, etc.
I believe Cambium wants you to use their QoE system to do it. I'm not sure what Ubiquiti does. Different equipment has different sized buffers. Very little additional functionality. -- Mike Hammett ----- Original Message ----- From: "Ken Hohhof" <[email protected]> To: "AnimalFarm Microwave Users Group" <[email protected]> Sent: Saturday, November 8, 2025 11:49:17 AM Subject: [AFMUG] FTTH speed tier mechanism 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”. -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
