This article compares traditional databases with modern cloud‑native data warehouses, outlines a detailed performance testing methodology using the SSB1000 benchmark, presents test scripts and environment setup for Cloudwave and StarRocks, and analyzes the results to highlight strengths and optimization opportunities.
This article explains how modern computer systems use a hierarchical memory structure and virtual memory to overcome physical memory limitations, address translation challenges, fragmentation, and security issues, detailing concepts such as page tables, TLB caching, multi‑level paging, and practical examples.
The article recounts the evolution of open source from the early days of UNIX and the GNU project to Linux’s rise, highlights Intel’s partnership with Chinese OS communities, and argues that open‑source collaboration and international cooperation are essential for future technological innovation.
This article explains Linux traffic control fundamentals, covering the three-layer processing model, queue types, token‑bucket mechanisms, kernel TC architecture, Qdisc/Class/Filter hierarchy, and provides step‑by‑step tc CLI examples for implementing QoS, DiffServ, and enterprise networking policies.
This article explains Docker's container networking concepts—including the CNM model, native drivers, bridge, host, macvlan, none modes, port mapping, overlay SDN—as well as storage options and Compose orchestration techniques for building robust cloud‑native applications.
This article explains the evolution of Segment Routing, its core concepts such as Segments, SIDs and Segment Lists, and how SR‑MPLS and SRv6 improve MPLS forwarding, TE, and data‑center overlay networking with UDP and load‑balancing techniques.
This article traces the evolution of wide‑area network technologies, explains MPLS label‑stack architecture and forwarding mechanisms, details MPLS VPN (L2VPN/L3VPN) components, routing information bases, RD/RT fields, and outlines classic and inter‑domain deployment models for modern carrier networks.
This article provides a comprehensive overview of dynamic routing protocols, detailing their basic operation, classification, common implementations such as RIP, OSPF, and BGP, performance metrics, BGP message structures, path attributes, route selection rules, and advanced concepts like route reflectors, multiprotocol extensions, and BGP‑LS for topology extraction.
This article traces the evolution of operating‑system level virtualization from the early UNIX chroot to modern Docker containers, explaining the roles of chroot, control groups, various Linux namespaces, their implementation details, and how Docker leverages these mechanisms for isolation and resource management.
This comprehensive guide explains the IPSec security suite—including AH, ESP, and SA protocols—covers encapsulation modes, NAT‑Traversal, MTU fragmentation issues, VPN deployment scenarios, Virtual Tunnel Interfaces, and provides step‑by‑step StrongSwan configuration and testing procedures.
