Packet loss refers to the situation where data packets are discarded during the transmission process due to various reasons before they reach the application program. The number of discarded packets divided by the total number of transmitted packets is what we commonly refer to as the packet loss rate. The packet loss rate is one … Read more
1. Introduction 1. Why use Ethernet for communication? Ethernet refers to a local area network that complies with the IEEE 802.3 standard. It is a type of internet technology, and since it occupies the highest proportion in networking technology, many people directly equate Ethernet with the internet. However, IEEE also has other local area network … Read more
TCP/IP ProtocolThe TCP/IP protocol (Transmission Control Protocol/Internet Protocol) is the most widely used protocol today, encompassing over 100 protocols used on the Internet, with the two most important being TCP and IP. Due to its cross-platform and routable characteristics, TCP/IP enables the interconnection of networks and communication across different network segments. This has led many … Read more

It provides a reliable means of communication for applications. In this article, we will delve into the composition of the TCP/IP protocol stack and its basic implementation in C++. 1. Overview of the TCP/IP Protocol … Read more
Introduction In the development of network applications, TCP/IP communication is fundamental for data transmission between clients and servers. However, ensuring the stability and reliability of communication is equally important. When implementing TCP/IP communication in C#, it is necessary to focus not only on sending and receiving data but also on monitoring the connection status in … Read more
Image course, development board –> Taobao store: Wolf FPGA ConsultationWeChat: MyWork666888 QQ group: 543928922 Recently, Wolf published an article on 100G networking titled “FPGA Project: 100G Network Development Sharing”. It is impressive that it can communicate, but the downside is that it only reaches the MAC layer, and the upper network layers are missing. To … Read more
