Q86 / 100
What is kernel bypass networking and how does io_uring relate?
Correct! Well done.
Incorrect.
The correct answer is B) Techniques (DPDK, AF_XDP, io_uring) that minimize kernel involvement in I/O paths, reducing context-switch and copy overhead for high-performance packet processing
B
Correct Answer
Techniques (DPDK, AF_XDP, io_uring) that minimize kernel involvement in I/O paths, reducing context-switch and copy overhead for high-performance packet processing
Explanation
DPDK maps NIC registers to user space. AF_XDP allows kernel bypass for selected packets. io_uring uses shared ring buffers reducing syscall overhead. Together, enable millions of packets/sec from a single CPU core.
