The Challenge

Speed alone doesn't fix a bad experience.

A subscriber can have a 1 Gbps plan and still have a terrible experience at peak hour. The reason isn't the raw speed — it's bufferbloat and head-of-line blocking.

When the link gets busy, data piles up in queues. Everything behind a big download waits in the same long line — including your video call, your game's heartbeat, your voice packet. The result: lag, freezes, choppy audio, frustrated subscribers.

More bandwidth doesn't fix it. It just delays it. The problem is how the queues are managed, not how large the pipe is.

Typical BNG queue at peak hour — bufferbloat
Large download fills the queue Interactive packets stuck waiting 100–300 ms added delay call/game/voice
Industry context

Latency, not speed, drives subscriber satisfaction. Studies consistently show that "lag" and "choppy calls" are the top reasons subscribers report poor experience — not raw throughput.

Support costs follow experience. "My internet is laggy / my call keeps dropping / games lag" is the single highest-volume driver of broadband support tickets — and it cannot be solved by selling a faster plan.

Churn follows dissatisfaction. Subscribers who experience quality problems are disproportionately likely to switch providers. Measurably excellent experience is the strongest retention lever available to an ISP.

The Solution

Four coordinated layers. One seamless experience.

Each layer handles a different dimension of the latency problem. Together they form a complete experience management system — integrated at the software level, running on existing BNG hardware.

AQM Smart Queue Management Layer 1 — Queue Control + L4S Signal, Don't Drop Layer 2 — Congestion Signaling + IFP Interactive Flow Protection Layer 3 — Priority Lanes + AEC Autonomous Controller Layer 4 — Self-Optimization RUNNING ON EXISTING BNG HARDWARE · ~3% CPU · NO NEW BOXES

🎯
Layer 1 — Queue Management

AQM — Smart Queue Management

Traditional BNG queues let data pile up into a long, slow queue when the link gets busy — causing everything to wait, including real-time traffic. AQM keeps the queue permanently short by managing it actively, so data never builds up in the first place.

What this means for your subscriber: the network adds almost no delay to anything they send or receive. Everything feels immediate, not sluggish.

Average queuing latency: 0.43 ms — vs 100–300 ms typical bufferbloat

📡
Layer 2 — Congestion Signaling

L4S — Signal, Don't Drop

When the link is at capacity, traditional networks simply throw away packets — a blunt, lossy response that forces applications to re-send data and causes stutter. L4S instead sends a gentle electronic "slow down" signal directly to the sender before any data is lost.

What this means for your subscriber: no stutter, no re-sends, no frozen frames — congestion is absorbed silently, without the subscriber ever noticing.

13.3M congestion signals vs only ~9,000 drops — 99.93% signal-not-drop

Layer 3 — Priority Lanes

IFP — Interactive Flow Protection

Even with good queue management, a massive download can compete with a game or a voice call. IFP recognises the traffic you feel — game moves, call audio, voice packets, clicks — and puts them in a dedicated fast lane. The big download still gets its bandwidth; it just can't bully the call.

What this means for your subscriber: the household can do everything at once — streaming, downloading, gaming, calling — and every one of them stays smooth.

Layer 4 — Self-Optimization

AEC — Autonomous Experience Controller

The first three layers set the rules. AEC enforces them continuously, automatically. It measures every subscriber's experience in real time, detects fleet-wide degradation before subscribers notice, adjusts the system parameters, and validates the improvement — all without human intervention.

What this means for your operations team: the network tunes itself. No shift-by-shift manual tuning, no reactive firefighting.

Subscriber Experience Score (0–100)

99% of subscribers: Excellent

Real-time per-subscriber scoring across the live fleet. The score measures the quality of each subscriber's actual internet experience, not just throughput.

99% EXCELLENT
Excellent 99.0%
Good 0.1%
Fair 0.1%
Poor 0.8%

† The 0.8% rated "poor" are individual subscribers who have maxed out their own plan's capacity — a billing/plan decision, not a network quality issue.

Queuing Latency — Before vs After

From 200 ms to 0.43 ms

The suite eliminates bufferbloat almost entirely. This is the single most impactful number for subscriber experience.

L4S — Congestion Handling Method

Signals vs Drops: 1,478× better

When congestion occurs, L4S signals the sender to slow down instead of dropping the packet. This is the difference between a smooth stream and a stutter.

Hardware Utilisation — Existing BNG

~3% CPU. Enormous headroom.

The entire suite runs on the existing BNG server. No new hardware, no extra boxes. At ~3% CPU on a 32-core server — carrying ~150 TB/day for 3,500+ subscribers.

~3% CPU USED 0% 100% Used 97% free
~150 TB/day throughput carried
3,500+ concurrent subscribers
97% CPU headroom available for growth
Zero additional hardware required

The hardware headroom means subscriber growth and feature additions do not require new servers or a forklift upgrade.

Scalability

Built to scale — one box, tens of thousands of subscribers.

The same software, on one existing server, scales from a few thousand to tens of thousands of subscribers while keeping sub-millisecond latency and the same per-subscriber experience — because the data-plane cost is tiny and grows gently.

† Projections are linear extrapolations of the live-measured data-plane cost (~0.00086% CPU per subscriber). The 3,500-subscriber figure is live-measured on a real production node. 20k and 30k figures are not yet field-validated at that scale.

Capacity & Economics

One server. No re-architecting.

The data-plane cost of this suite is approximately 0.00086% CPU per subscriber — a near-linear, predictable, tiny number. That means adding subscribers does not surprise you with runaway compute costs.

Even at 30,000 subscribers on a single server, ~70% of the CPU stays free — available for other services, future features, or simply as comfort margin.

3,500 subs / ~3% CPU — live-proven on a real production node. 97% headroom remains.
20,000 subs / ~20% CPU — projected. 80% headroom. Sub-ms latency maintained throughout.
30,000 subs / ~30% CPU — projected. 70% headroom. Same per-subscriber experience.
Business implication

One server does the work of many — defer hardware spend, consolidate, grow without re-architecting. When you do need a second server, you'll know exactly when and why.

Autonomous Operation

The self-driving network.

The Autonomous Experience Controller (AEC) is a closed-loop system that continuously measures experience, diagnoses problems, makes targeted adjustments, and validates the outcome — with no human input required.

MEASURE per-sub score DIAGNOSE real problem? TUNE adjust params VERIFY confirm & revert CONTINUOUS LOOP — NO OPERATOR INTERVENTION REQUIRED
📊

Measure — continuously, per subscriber

AEC scores every subscriber's experience in real time on a 0–100 scale. It sees the whole fleet, not just aggregate statistics.

🔍

Diagnose — is this a real fleet-wide problem?

AEC only acts when it detects a genuine, statistically significant, fleet-wide issue — not individual variation. This prevents over-reaction to noise.

⚙️

Tune — targeted, minimal intervention

AEC makes the smallest parameter change that addresses the root cause. It doesn't re-tune the whole system — it adjusts the one lever that matters.

Verify & revert — safe by design

After every adjustment, AEC re-measures. If the experience didn't improve, it reverts immediately. It never locks in a change that doesn't demonstrably help.

Live Production Evidence

Held 99/100 experience score on 3,500+ subscribers

During normal fleet operation, AEC continuously monitored experience and correctly determined that zero intervention was required — because the baseline suite was already delivering excellent experience. This is the right outcome: a self-driving system that acts when it should and does nothing when it shouldn't.

Business Case

Four money levers. Zero new hardware.

The suite doesn't just improve subscriber experience — it transforms the economics of delivering it. Here are the four business outcomes that directly affect the bottom line.

Capital Expenditure $0

Hardware spend deferred

The entire suite runs as software on the existing BNG, using ~3% CPU. No new servers, no QoS appliances, no extra switching gear. The hardware you already have handles it — with 97% headroom to spare.

Subscriber growth is absorbed by the existing investment. Capacity upgrades become a choice, not a necessity, for years longer.

Operational Expenditure

Support ticket volume reduced

"My internet is laggy" and "my call keeps dropping" are the single largest category of broadband support contacts. They are solved entirely by this suite — not by providing more bandwidth, but by fixing the queue management that causes them.

The AEC layer adds further OpEx relief: the network monitors and tunes itself, eliminating the shift-by-shift manual QoS management burden.

Subscriber Retention 99%

Experience protects the base

Experience quality is the primary reason broadband subscribers churn to a competitor. A measurably excellent experience score across 99% of the subscriber base is the strongest churn defence available — more durable than promotional pricing, and independent of plan size.

Subscribers who never have a bad experience don't look for alternatives.

Revenue Opportunities +

New premium tiers enabled

The suite creates a genuine, demonstrable technical differentiation that can be monetised. Examples: a "Gaming & Creator" low-latency plan tier; a "Business Quality" VoIP guarantee; per-application experience SLAs. Sell experience, not just megabits.

These are premium offerings that competitors without this infrastructure cannot credibly match.
