YARP: A highly customizable reverse proxy built with .NET

Reverse proxy is a common network technology that can achieve a variety of functions, such as load balancing, caching, compression, transcoding, etc. And plays an important role on the Internet, improving the performance, reliability, and security of websites. However, it is not easy to build a high-performance, reliable and customizable reverse proxy. The existing reverse […]

Matlab implements image filtering, edge extraction (five operators), and sharpening (two gradient operators)

1. Experiment purpose 1. Image 3*3 mean filtering and median filtering. 2. Use gradient, sobel, and Laplacian operators to sharpen the image. 3. Use multiple operators (at least five) to extract edges from the image. Compare the characteristics of each operator, analyze the processing results, find out where in the image the processing effect is […]

Opencv C++ 5. Simple image sharpening and convolution operations

Introduction: Image sharpening and convolution are commonly used techniques in image processing, and their main purposes are as follows: 1. Image sharpening: Image sharpening is a technique used to enhance image details and edges. It makes images look sharper and more textured by emphasizing high-frequency information in the image, such as edges and details. Sharpening […]

2.3 Switch and ARP

1. Ethernet frame format a. MAC address When computers are connected to the Internet, the hardware required for networking is the network card. A physical address burned into the network card is the MAC address, and the MAC address of each network card is a unique number in the world. The MAC address is composed […]

WireShark ARP protocol analysis

Protocol introduction ARP (Address Resolution Protocol) is a communication protocol used to resolve physical addresses in IP networks. Its function is to convert IP addresses into MAC addresses in order to transmit data packets in the LAN. The ARP protocol usually runs on Between the network layer and the data link layer, it implements IP […]

16.2 ARP host detection technology

ARP (Address Resolution Protocol) is a protocol used to convert an IP address into a physical address (MAC address). It is at the link layer in the TCP/IP protocol stack. It is designed to correctly transmit data packets in the local area network. It consists of protocol data units and corresponding operation commands. ARP can […]
