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 explains Linux's virtual network devices—including Tap and Tun virtual NICs, Veth-pair links, Bridge bridges, Network namespaces, VLAN sub‑interfaces, MACVLAN and MACVTAP—detailing their architecture, driver components, configuration commands, and practical examples for building isolated or connected virtual networking environments.
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 article uses a restaurant analogy to demystify Keepalived’s routing mechanisms, detailing the three routing modes—NAT, TUN, and Direct Routing (DR)—their configurations, underlying principles, advantages, limitations, and practical deployment considerations within load‑balancing environments.
This article explains the architecture of Linux Virtual Server (LVS) load balancers, detailing the roles of the Director server, Real servers, shared storage, and the three primary IPVS scheduling modes—DR, NAT/FULL NAT, and TUN—including their mechanisms, advantages, and configuration considerations.
