WebSocket Signaling LifecycleSignaling path vs media transport logic
1
Authenticate Gateway

Client checks token validation scopes; establishes persistent TCP WebSocket link.

2
Event Subscription Hub

Gateway updates status presence cache; subscribes client to Redis Pub/Sub channels.

3
Signaling Negotiate

WebRTC SDP offer/answer exchanges propagate through signaling socket.

4
Session Closed / Unsubscribe

Socket close event triggers Redis cache TTL update, purging status keys.

WebRTC Media Routing PathPeer-to-peer vs TURN relay fallback rules

Direct Peer-to-Peer transport resolves whenever firewalls allow. If NAT traversal blocks direct connection, signaling dynamically routes media through TURN servers.

Provider Fallback ArchitectureProvider-neutral fallback designs
If secondary media provider gateways encounter degradation, signaling loops route connection requests to alternative servers, adjusting codecs to fit.
Adaptive Bandwidth Decision BoardInteractive network conditions simulator (illustrative limits)
Active network Condition:Strong Network Link
Voice Target Bitrate:64 kbps Stereo (HQ)
Preferred Codec Profile:OPUS HQ Stereo
Video Streaming Frame:1080p @ 30fps Video
Platform action:Unrestricted Media Streams
Offline SQLite queue modelDevice cache database buffers
Incoming voice and text streams serialize into SQLite on the client device during network loss, executing replay checks to avoid duplicate server writes.
Observability & Recovery MatrixIllustrative recovery blueprints for system failures
WebSocket disconnects

Impact: Losing live PTT signals

Recovery: Queue messages to local SQLite; try backoff reconnect loops

Redis cluster outages

Impact: Desyncing status lists

Recovery: Fallback to REST API polls; query database replica collections

Media provider gateway failure

Impact: WebRTC call dropouts

Recovery: Negotiate audio-only fallback relays through TURN

Encryption Key Strategy BlueprintProtected transport vs client-side encryption options
Server Transport Encryption

All signaling WebSocket traffic and REST requests run TLS transport channels. Direct server-side data encryption protects databases logs.

End-to-End Cryptography direction

Client-side encryption keys models reside in local keystores to prevent server interceptions, requiring separate verification reviews before launch.

Security Trust Boundaries MapAuth filters and API rate limiting gates
API Gateways rate-limit requests to stop DDoS overflows. Secure authorization filters inspect every request, blocking non-admin users from accessing evidence directories.
Object Storage expiring LinksExpiring signature links file delivery

Media uploads generate encrypted files on object storage. Gateway generates signed target download URLs containing expiry timestamps (e.g. 5m) to block access leaks.

Deployment & Scale BlueprintLoad balancers and databases replica clusters
Load balancers distribute WebSocket client sessions. Database replica sets shard collections to prevent signaling bottlenecks under load.

Security and Architecture Compliance review

All system boundaries models, REST service routes, WebSocket Pub/Sub event schemas, TURN fallback designs, database sharding diagrams, and WebRTC codecs adjustments are architectural visualizations. Live penetration testing records, SOC 2 certificates, or automated network throttling simulations are not active. Security validation is required.
