Heartbeat Mechanism for Communication Between C# Host and PLC

In the world of industrial automation, communication between the host computer and PLC is like the heartbeat, which is crucial for the stable operation of the entire system. The heartbeat mechanism, as an effective means to ensure that both parties in communication are always synchronized, is vital for maintaining system reliability. Let us explore the … Read more

Building a C++ Network Library from Scratch: My Journey in High-Performance Socket Programming

Building a C++ Network Library from Scratch: My Journey in High-Performance Socket Programming

1. Why Rewrite a Network Library? During my learning process of C++ network programming, I found that the native Socket API has poor cross-platform compatibility, complex error handling, resource management issues leading to leaks, and a lack of advanced features. Therefore, I decided to encapsulate a high-performance and user-friendly network library. 2. Core Design 2.1 … Read more

Detailed Explanation of Heartbeat, Packet Loss Retransmission, and Connection Timeout Mechanisms in the TCP/IP Protocol Stack

Detailed Explanation of Heartbeat, Packet Loss Retransmission, and Connection Timeout Mechanisms in the TCP/IP Protocol Stack

Recently, we encountered a project where the client’s network environment was unstable, leading to occasional packet loss and network jitter. This caused our software client to intermittently disconnect from the server, interrupting ongoing video conferences. This article takes this opportunity to explain in detail the heartbeat mechanism, packet loss retransmission mechanism, and other related content … Read more
