The article analyzes why a high‑concurrency data‑collection service quickly saturates a 100 Mbps uplink due to large TLS handshake payloads, demonstrates the bandwidth savings of switching to plain HTTP or using Keep‑Alive, and highlights practical considerations for secure versus performance‑optimized deployments.
This article explains how TCP ensures reliable data transfer through connection management, sequence and acknowledgment mechanisms, retransmission strategies, flow control, and congestion control, and includes C++ example code illustrating a simple client‑server file transfer implementation.
This article provides a comprehensive overview of the Transmission Control Protocol (TCP), covering its connection‑oriented design, reliability mechanisms, three‑way handshake, four‑step termination, packet structure, flow and congestion control, and practical C++ socket examples for establishing, sending, receiving, and closing connections.
This article explains how the Linux kernel maintains the SYN (half‑connection) and Accept (full‑connection) queues during the TCP three‑way handshake, describes their size limits, overflow handling, and common defenses against SYN‑flood attacks.
This article explains the OSI seven‑layer model and the simplified four‑layer TCP/IP model, describes the TCP/IP protocol suite, details how data is encapsulated and transmitted, compares TCP and UDP, and walks through TCP’s three‑way handshake, four‑way termination, and related security considerations.
This article provides a comprehensive overview of TCP, UDP, and HTTP protocols, explaining their definitions, layered roles, connection establishment and termination processes, segment structures, and key differences in reliability and performance for network communication.
This article provides a comprehensive overview of TCP and UDP, explaining their roles in the transport layer, key differences, the three‑way handshake and four‑way termination processes, data transmission mechanisms, and typical use‑case scenarios for each protocol.
This article explains the OSI seven‑layer model and the simplified four‑layer TCP/IP model, describes how data is encapsulated with headers at each layer, compares TCP and UDP characteristics, and details the TCP three‑way handshake, four‑way termination, and related security considerations.
This article provides a comprehensive overview of TCP and UDP, explaining their roles in the transport layer, key differences in reliability and speed, the three‑way handshake and four‑way termination processes of TCP, and how data transmission is handled by both protocols.
This article explains the fundamental differences between TCP and UDP, covering their purposes, reliability, speed, handshake mechanisms, data transmission processes, and termination procedures, and includes visual diagrams to illustrate each concept in.
This article provides a comprehensive overview of TCP and UDP, explaining their roles in the transport layer, key differences, the three‑way handshake, data transmission mechanisms, four‑way termination, and the characteristics of UDP, illustrated with diagrams for clarity.
The article investigates how loss of TCP SYN, SYN‑ACK, or ACK packets during the three‑way handshake affects MySQL client‑server connections, demonstrating retransmission behavior, kernel parameter tuning, and keep‑alive mechanisms through controlled iptables and tcpdump experiments.
This article provides an in‑depth tutorial on TCP, covering its header structure, three‑way handshake, reasons for three handshakes, four‑way termination, TIME_WAIT, SYN attacks, Linux kernel parameters, and practical socket programming examples, all illustrated with diagrams and code snippets.
This article explains TCP's core mechanisms—including acknowledgment (ACK), timeout retransmission, the three‑way handshake for establishing connections, and the four‑way handshake for graceful termination—while illustrating each concept with diagrams and addressing common interview questions.
This article provides a comprehensive overview of TCP networking fundamentals, covering the OSI seven‑layer model, TCP header fields, the three‑way handshake and four‑way termination, connection limits, packet fragmentation and reassembly, flow‑control mechanisms, HTTP/HTTPS differences, encryption methods and useful analysis tools.
After repeated domain takedowns, Sci-Hub's founder registered a new site on the Handshake decentralized DNS network, allowing users worldwide to reach the database via NextDNS and HNS gateways, while the article explains Handshake's operation, market growth, and its broader implications for Web 3.0 censorship resistance.
This article explains the complete process from entering a URL to rendering a web page, covering URL parsing, DNS resolution, TCP three‑way handshake and four‑way teardown, HTTP request/response structure, and browser rendering, while also clarifying TIME_WAIT and related socket states.
This article explains the MySQL client‑server communication protocol, detailing the connection phase—including handshake, authentication, and packet structure—as well as the replication process, covering registration as a slave, binlog streaming, and the various binlog event types and their formats.
