This article introduces the relevant knowledge of "what is the role of server network adapter". In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

What is the role of the server network adapter? In traditional environment, the processor needs to deal with the contents including encapsulation and unloading of IP packets and calculation and viewing, etc. With network adapters, the processor can process instructions more efficiently. Server network adapter features account for many, we will be a little difficult in the selection of characteristics of the network adapter, for everyone to introduce the role of the server network adapter includes what content.

segmentation offload

Data is transmitted in segments across the network, with 1,448 bytes per packet, matching TCP, IP, and data link layer headers. Traditionally, processors prepare segmented data and prepare packets. For example, moving a block of 65,536 bytes requires the processor to create and send at least 46 packets.

If the network adapter handles segment offload, the processor can send all data segments to the network adapter. This skill is often referred to as TCP Segmented Offload (TSO) or Large Block Offload (LSO).

checksum offload

Checksum algorithms scan TCP and User Datagram Protocol packets for faults. Validation ensures that the network adapter validates packets when they are received.

Active nodes may exchange millions or even billions of data packets every day. If the server processor can offload the computation and checksum comparison tasks to the network adapter, then the overall functionality of the system can still be improved.

Select network adapters that support IPv4 and IPv6 transmit and receive offloads checksum calculations. Network adapters for secure communications can also offload cryptographic checksum calculations and authentication without consuming server processor resources.

"What role does the server network adapter have?" The content is introduced here. Thank you for reading. If you want to know more about industry-related knowledge, you can pay attention to the website. Xiaobian will output more high-quality practical articles for everyone!
