This article explores Netty’s low‑level data container ByteBuf by examining Java NIO Buffer design, its core attributes, view mechanisms, heap and direct implementations, byte‑order handling, and how to read and write primitive types, providing a comprehensive foundation for high‑performance network programming.
This article explains how Linux handles local network I/O for 127.0.0.1, detailing the differences from cross‑machine communication, the routing decisions, the loopback device driver, soft‑interrupt processing, and the complete kernel execution flow for both sending and receiving packets.
This article provides a detailed source‑code walkthrough of DBLE’s network module, explaining how it processes MySQL packets, implements selector‑based multiplexing, and performs asynchronous task handling to achieve high‑performance database communication for client connections.
This article explains the fundamentals of traditional socket programming and compares it with Netty's architecture, covering server and client components, HTTP request handling steps, Netty's NioEventLoop, Channel, ByteBuf, Pipeline, and unsafe implementations, all illustrated with diagrams and code snippets.
The article analyzes real‑world network and disk I/O issues encountered in Qunar Message Queue (QMQ), explains root causes such as Netty OOM, file‑handle exhaustion, TCP timeout handling, and large‑traffic bursts, and presents practical mitigation strategies for backend systems.
This article provides a comprehensive technical guide to DPDK and SPDK, covering their background, architecture, user‑space I/O bypass mechanisms, core performance optimizations such as HugePages, SIMD and cache management, and practical ecosystem recommendations for building high‑throughput network and storage services.
