Ensuring 60‑Second TCP Keep‑Alive During Unstable Networks

Facing frequent packet loss and network jitter that disrupts video conferences, this article examines TCP/IP stack heartbeat and retransmission mechanisms, demonstrates how to configure Windows keepalive parameters, and provides code examples for custom socket options and non‑blocking connect timeouts to maintain session continuity within 60 seconds.

Understanding Sentinel Cluster Rate Limiting and Handling Network Jitter

Sentinel’s cluster rate limiting adds a centralized token server that grants tokens to client instances before processing requests, and when network jitter causes request timeouts the client automatically falls back to local limiting, so configuring short request‑timeout values (e.g., 20 ms) is crucial for maintaining low latency and high availability in elastic, multi‑instance deployments.
