LATENCY & EXPERIENCE

“The internet is slow.” The line is at full speed. Both are true.

A full line is not a slow line — but it feels like one. Bufferbloat turns about a millisecond of idle delay into tens of milliseconds the moment someone starts an upload. Speed tests keep passing while the complaints keep coming.

Sell what the subscriber actually feels

Plan rate is what you sell. Latency under load is what decides whether they call you.

L4S and low latency

Congestion is signalled rather than caused. Marks instead of drops, so a video call and a large upload can share the same line without the call breaking up.

Fair queuing (AFD)

When one device saturates the line, the rest of the household should not stop working. Flows are isolated so a single heavy sender cannot take the whole queue.

Interactive flow protection

Gaming, voice and interactive web are kept snappy even when the line is full — without asking the subscriber to buy a bigger plan.

App-aware QoS

Deliver the plan rate precisely, make it feel fast, and hold latency down under load — in one data plane rather than three appliances.

Autonomous QoE

The gateway learns what normal looks like for each subscriber and acts on the ones that drift, instead of waiting for a ticket.

Flow intelligence

Measure, scavenge, score and remediate — subscriber experience as a number you can act on rather than an opinion.
