The article examines how IPv6 was designed to eliminate decades‑old networking baggage, but its reliance on discarding legacy layers, MAC addresses, ARP, and DHCP makes the ideal blueprint unattainable in today’s mixed‑technology Internet.
This article explains how Ethernet switches learn MAC addresses, forward frames, prevent loops, and differ across store‑and‑forward, cut‑through, and multi‑layer designs, while also covering routing fundamentals, layer‑3 switching operation, and the principles of layer‑4 load‑balancing switches.
Understanding a Web 3.0 DApp’s architecture involves replacing the centralized database and backend of a Web 2.0 stack with Ethereum’s immutable blockchain and smart contracts, while the front‑end communicates via providers, uses off‑chain storage like IPFS, queries through events or The Graph, scales with Layer 2 solutions, and leverages tools such as Hardhat, Truffle, and Remix.
This article explains VLAN fundamentals, why they are needed, how they differ from subnets, the role of VLAN tags and IDs, various interface types, practical deployment scenarios, related protocols, and the challenges VLANs face in modern cloud environments.
This article explains the operating principles, main functions, characteristics, and classifications of Ethernet switches, covering layer‑2 learning and forwarding, layer‑3 routing, layer‑4 load‑balancing, and the technical criteria used to evaluate switch performance.
This article provides a comprehensive overview of network switches, covering their definition, MAC‑based operation, port expansion, classification by manageability and OSI layer, various management methods (Web, CLI, SNMP), product specifications, application scenarios, and key features such as VLAN, port isolation, aggregation, loop detection, ACL, ARP protection, DHCP services, and routing capabilities.
This article explains the problems of layer‑2 loops and broadcast storms, how VLAN segmentation and spanning‑tree protocols mitigate them, and introduces TRILL technology for scalable data‑center networks, providing detailed concepts, mechanisms, and practical examples for network engineers.
The Lightning Network is a layer‑2 protocol for Bitcoin that creates off‑chain payment channels enabling near‑instant, low‑cost transactions by routing payments through a network of multi‑signature wallets, and while still under development, it promises to significantly improve cryptocurrency scalability.
The article explains why traditional Layer‑2 networks hinder VM live migration in dual‑active data centers, introduces the concept of big‑layer networking, and details how VxLAN overcomes VLAN limits and loop issues to enable uninterrupted cross‑site service continuity.
