This article explores the strategic role of eBPF in cloud‑native operations, detailing its technical foundations, real‑world use cases from major tech companies, step‑by‑step troubleshooting methods, and a concrete implementation for TCP retransmission monitoring in a high‑traffic gateway system.
This article explains how packet loss in TCP/IP networks triggers retransmissions that dramatically increase HTTP latency, reduce throughput, and cause cascading failures, then details an experiment using ChaosMesh to quantify these effects across different payload sizes and loss rates, and offers practical testing guidelines.
This article explains the concept of full‑path packet loss monitoring, its importance for banking networks, the causes of packet loss, and detailed technical implementations—including traffic splitting, collection, automatic analysis engines, TCP retransmission detection, and algorithms for pinpointing loss locations—to dramatically reduce troubleshooting time.
