This article explains the core concepts of Linux Virtual Server (LVS), details its four operating modes—NAT, Direct Routing, TUN, and FULLNAT—and provides step‑by‑step configuration guidance, including ARP handling and kernel parameter tweaks for reliable load balancing.
This guide explains the core concepts of Linux Virtual Server (LVS), detailing its key components, client request flow, and the four operating modes—NAT, Direct Routing, TUN, and FULLNAT—along with practical ARP handling and mode‑by‑mode comparisons for effective load balancing.
This article explains the Linux Virtual Server (LVS) load‑balancing architecture, defines key terms such as VS, RS, VIP, DIP, and CIP, and details the four operating modes—NAT, DR, TUN, and FULLNAT—including their workflows, configuration steps, and practical considerations.
This article uses a restaurant analogy to demystify Keepalived's routing mechanisms, detailing the NAT, TUN, and Direct Routing (DR) modes, their configurations, underlying LVS architecture, performance trade‑offs, and practical deployment considerations for high‑availability load balancing.
This tutorial explains how to use the ipvsadm command to create and manage LVS/NAT and LVS/DR load‑balancing clusters on Linux, covering command syntax, environment setup for director and real servers, ARP tuning, rule persistence, and extended exercises for HTTP, HTTPS, and MySQL traffic.
The article presents a DR + GNSS playback tool for Amap’s Android car‑navigation system that mimics sensor fusion via a custom AIDL protocol, supports existing log formats, runs in an independent process, and streamlines QA by cutting verification time from hours of road testing to under thirty minutes.
This comprehensive tutorial explains the fundamentals of Linux Virtual Server (LVS), its architecture, scheduling algorithms, and detailed step‑by‑step configurations for NAT, DR, and Tun modes, including scripts, iptables rules, and keepalived HA integration, with testing procedures and reference links.
This guide explains the fundamentals of Linux Virtual Server (LVS), covering cluster concepts, types, scheduling algorithms, ipvsadm commands, and detailed configuration examples for NAT and DR models, culminating in a complete web‑server load‑balancing deployment with Discuz on CentOS.
