• #30542 — Understanding TCP and UDP Networking Protocols — Представитель этого кластера

  TCP и UDP, или Два столпа Интернета — notadev

  Смысл: The main idea is to explain how the TCP/IP stack enables reliable and efficient communication across the Internet by utilizing packet switching and specific transport protocols (TCP for reliability, UDP for speed).

  An educational guide explaining the differences between TCP and UDP protocols and how the TCP/IP stack manages data transmission on the Internet.

• #15698 — Experimenting with Custom IP Transport Protocols

  Что будет, если не использовать TCP или UDP? — Basis_Habr

  Смысл: The main idea is to demonstrate that while creating a custom transport protocol is technically possible at the code level, the actual network infrastructure (NATs, firewalls, and OS kernels) is designed specifically for TCP, UDP, and ICMP, making any alternative impractical for global communication unless using IPv6.

  An experiment showing that custom IP protocols are generally blocked by OS kernels and network hardware in IPv4, but can function over IPv6.

• #16119 — The Journey of a Packet Through Network Hardware

  Сети для самых маленьких. Часть четырнадцатая. Путь пакета — eucariot

  Смысл: The main idea is to demystify the 'black box' of network hardware by explaining the synergy between software (Control Plane) and specialized hardware (Data Plane) that allows modern routers to forward billions of packets at light speed.

  A comprehensive technical guide explaining the hardware architecture and internal processes that enable high-speed packet forwarding in professional networking equipment.

• #29170 — Optimizing and Measuring High-Speed TCP Connections

  Как получить и измерить высокоскоростное соединение по TCP — prox

  Смысл: The main idea is that achieving maximum network throughput requires more than just a fast physical link; it necessitates the optimization of the TCP stack (specifically window sizes and congestion control) to overcome the limitations imposed by latency and packet loss.

  A technical guide explaining how TCP window sizes, latency (BDP), and packet loss limit network speed and how to optimize the protocol stack and measure performance using nuttcp.

• #30323 — Foundations of Computer Networks: Devices and Cabling

  Основы компьютерных сетей. Тема №4. Сетевые устройства и виды применяемых кабелей — solid_93

  Смысл: The text serves as an educational guide explaining the physical and logical components of computer networks, specifically focusing on networking hardware (hubs, switches, routers) and the types of cabling used to connect them, utilizing simulations to demonstrate how data flows through these devices.

  A detailed educational guide explaining the functions of hubs, switches, routers, and various network cables using Cisco Packet Tracer simulations.
