Why Unreliable Networks Threaten Distributed Systems and How to Mitigate Them

Distributed systems suffer from network unreliability—including packet loss, out‑of‑order delivery, variable latency, and ambiguous node failures—making timeout settings and fault detection challenging, and this article explains these issues, compares synchronous and asynchronous networks, and discusses strategies to balance latency and resource utilization.
