Translation: The Working Principles and Development Trends of Smart Network Interface Card Smart network interface card, also known as a network processor card, is a hardware device used for data transmission between a computer and a communication network. Its working principles mainly involve the following aspects: 1. Data Transmission: The smart network interface card interacts with the CPU and memory of a computer to receive and send data packets. When a computer needs to send data through the network, the smart network interface card is responsible for converting the data packet into a format that can be transmitted on the network and sending it out through the network interface. 2. Hardware Acceleration: The smart network interface card uses dedicated processing units to perform tasks related to network data transmission, reducing the burden on the main CPU. It can quickly process large amounts of network data, thereby improving the efficiency of data transmission. 3. Driver and Protocol Support: Smart network interface cards need to interact with the operating system of a computer, so they contain necessary drivers and protocol support. These drivers and protocols allow the smart network interface card to understand and execute various network protocols such as TCP/IP and UDP. II. Development Trends of Smart Network Interface Card With the continuous development and progress of network technology, smart network interface cards are also constantly evolving. Its future development trends are mainly reflected in the following aspects:
