Internet Speed Test Methodology - How We Measure Your Connection Speed

HOW WE MEASURE IT?

01. THROUGHPUT ARCHITECTURE

The Flux Network engine bypasses traditional HTTP latency by establishing 6 concurrent TCP streams directly to the Cloudflare Edge network.

Multi-Threading: We utilize the fetch API in parallel workers to saturate the available bandwidth, compensating for TCP slow-start protocols.
Cloudflare Anycast Routing: We do not rely on a single central server. Instead, our engine utilizes Cloudflare's global Anycast network. This technology automatically routes your connection to the physically closest of 330+ data centers worldwide. This is intentional: it ensures we measure your "Last Mile" connection speed (ISP capacity) rather than the latency of the open internet.
Server Verification: During the diagnostic process, we query the cdn-cgi/trace endpoint to cryptographically verify exactly which Colocation Center (Colo) you are connected to (e.g., IAD for Ashburn, LHR for London), providing total transparency on the test target.
Overhead Compensation: Results include a 1.05x multiplier to account for IP/TCP header overheads, providing a more accurate representation of Layer 1/2 capacity.

02. LATENCY & JITTER (RFC 3550)

Responsiveness is measured using high-frequency probes (~200ms interval) to the edge. We calculate Jitter using the standard Real-time Transport Protocol (RTP) formula defined in IETF RFC 3550.

J(i) = J(i-1) + (|D(i-1,i)| - J(i-1)) / 16

Where D(i-1,i) is the difference in packet arrival timing. This provides a exponentially weighted moving average that accurately reflects network stability for VoIP and Gaming.

03. BUFFERBLOAT & PACKET LOSS

Bufferbloat occurs when routers buffer too much data, causing high latency during transfers. We measure this by comparing Idle Latency vs. Loaded Latency (during max speed).

Grade A+

Delta < 5ms

Grade A

Delta < 30ms

Grade B

Delta < 60ms

Grade C

Delta < 150ms

Packet Loss is monitored via WebRTC Data Channels. If WebRTC is blocked, we use a heuristic based on failed HHR requests.

04. QUALITY OF EXPERIENCE (QoE)

Raw metrics are synthesized into application-specific scores (0-100).

Gaming Score Weighted blend: 50% Latency (<20ms ideal), 20% Jitter, 30% Throughput.
Video Score Evaluates buffering risk (Jitter) and HD capacity (Speed > 25Mbps).
Web Score Focuses on page load time simulation, rewarding low latency and moderate speed (>10Mbps).

05. AI READINESS

This module evaluates your connection's suitability for Large Language Models (LLMs) and Generative AI.

Provider Latency We measure the Round Trip Time (RTT) of the initial SSL/TLS handshake to the edge servers of major providers (Anthropic, Google, and OpenAI). This indicates how quickly your network can initiate requests.
Token Streaming Stability Simulates the network pattern of receiving an AI response (streaming tokens) by fetching small chunks of data repeatedly. We measure the variance (jitter) between chunks to calculate a stability score.
WebSocket RTT Measures the responsiveness of a persistent WebSocket connection, critical for real-time chat interfaces.
