BJNet Monitor — QUIC Dashboard

Network Service Level Distribution

Shows the percentage distribution of measured upload and download bandwidth across predefined throughput ranges (Mbps).

—

Tests Analyzed

Round-Trip Time Distribution

Displays the percentage of sessions grouped by latency ranges to assess network responsiveness.

Packet Loss Rate Distribution

Illustrates the proportion of sessions experiencing different packet loss levels, highlighting potential network degradation.

Acknowledgment Delay Distribution

Represents the distribution of acknowledgment delays observed during QUIC sessions, indicating transport efficiency.

Concurrent QUIC Streams per Session

Shows how many parallel QUIC streams are opened per session, reflecting the protocol's parallelization behavior.

Network Congestion Pressure Index

Provides a synthetic indicator of congestion pressure derived from the ratio between bytes in flight and the congestion window.

RTT Stability per ISP

Min / Avg / P90 / Max RTT per ISP (top 12 by sessions).

RTT Jitter Distribution

Average RTT variance per session (jitter).

RTT Spread (Max - Min)

Per-session spread between maximum and minimum RTT — high values indicate unstable routes.

Congestion States Frequency

Percentage of sessions that crossed each BBR / Cubic congestion state.

Loss Trigger Causes

Distribution of packet loss detection triggers (time threshold vs reordering threshold).

Saturation Ratio

Distribution of bytes_in_flight / cwnd — actual utilization of the congestion window.

P90 (critical)

Sessions per Hour of Day

Hourly UTC distribution of QUIC sessions and average RTT.

Activity Heatmap (Day × Hour)

Sessions per day-of-week × hour-of-day — reveals peak usage patterns.
