What is the internet interface card and what can it be used for?
If you are interested in the NCI card, then you should read this post carefully.
Definition of web connection Interface Card
To begin with, what is the web connection interface card?
Early web link interface cards were usually implemented on expansion cards inserted into the computer bus.
Newer server motherboards may have multiple internet interfaces built-in.
Ethernet controllers usually have an 8P8C socket for connecting internet cables.
Earlier NICs also provided BNC or AUI connections.
Ethernet online grid controllers usually support 10 Mbit/s Ethernet, 100 Mbit/s Ethernet, and 1000 Mbit/s Ethernet.
Modular designs like SFP and SFP+ are very popular, especially in fiber-optic communications.
The NIC can use a hash function to distribute incoming traffic between receive queues.
With multi-queue NICs, performance can be improved by distributing outgoing traffic among different transmission queues.
By assigning different transmit queues to different CPUs or CPU cores, internal operating system contention can be avoided.
This method is commonly referred to as transmission packet steering (XPS).
It is mainly used for high-speed web connection interfaces like Gigabit Ethernet and 10 Gigabit Ethernet.
For these interfaces, the processing overhead of the web connection stack becomes very large.
