Network Resilience

Session Reconnect & Recovery

Grace-period protocols, transient socket disconnect handling, and event diff replay enabling seamless match resumption.

Network Disconnect Grace & Reconnection Protocol

Resilience Timeline
ILLUSTRATIVE RESILIENCE PROTOCOL · Disconnect Grace & Session Handshake
State Resilience

Phase 1: Packet Loss Detected

Window: 0s - 3s
Client Behavior

Local socket heartbeat misses 3 consecutive ping frames; renders reconnect HUD overlay.

Server Action

Marks socket session as TRANSIENT_DISCONNECTED; freezes match turn timer to prevent penalty.

System Outcome: Room state preserved in Redis memory cache.
Pillar 01

Transient Disconnect Grace

Match turn clocks freeze during brief packet loss windows to avoid unfair penalties.

Pillar 02

Resumption Handshake

Session resumption tokens validate reconnection and stream missed game events.

Pillar 03

Deterministic Timeout Fallback

Graceful timeout triggers auto-play or forfeit if connection cannot be re-established.

Transient Socket Resilience & Handshake Specs

  • Redis memory-cached room state preserved during transient disconnects
  • Client UI state synchronization upon socket reconnection
  • Configurable grace-period thresholds per casual game mechanic
