Quality Support for Every Live Session

Each session is reviewed across media quality, device checks, network paths, and service events.

01

Quality Diagnostics

Tracks audio, video, connection, and latency signals for each participant.

"Why can Alex not hear the teacher?"
02

Root Cause Analysis

Connects WebRTC metrics, logs, node load, carrier quality, and classroom context.

"Why was last night's 8 PM open class stuttering?"
03

Service Reports

Creates post-class summaries, SLA notes, and incident reviews.

"Generate this week's classroom quality report."
04

Capacity Planning

Uses schedules, peak history, and live usage to flag capacity risk.

"Do we need to scale resources before tomorrow night's open class?"

The Right View for Every Team

What They Need to Know

A student cannot hear audio A student's video is stuttering In-class interaction issues Pre-class device checks

Response style: clear, brief, and actionable.

"Microphone access is blocked in the student's browser. Ask the student to allow microphone access and rejoin the class."

What They Need to Know

Courses with quality issues Teachers with quality dips Regions with higher disconnect rates Weekly service overview

Response style: concise enough for a service review.

"Over the past week, 326 classes ran. Eighteen had noticeable stuttering, mostly on mobile networks in South China. Enable poor-connection adaptation for evening peak sessions."

What They Need to Know

SFU node load Unexpected TURN relay ratio Regional network changes Release impact Root cause and next steps

Response style: technical, traceable, and action-ready.

"From 20:02 to 20:11, the TURN relay ratio increased in East China while SFU CPU remained normal. Switch to the backup entry point and reduce default upstream bitrate."

Operations Review

Review Class Quality in Plain English

Query

Why was last night's 8 PM open class stuttering?

The issue appeared between 20:03 and 20:09, mainly for mobile users in East China. SFU CPU and memory stayed normal, while the TURN relay ratio rose from 16% to 41% and average RTT reached 230 ms.

Report Request

Generate a customer-readable incident review.

Summary: a regional network issue affected about 3.5% of attendees. Node routing has been adjusted, and weak-network adaptation will be enabled for similar evening peak sessions.
