What is kernel-bypass networking (e.g., DPDK)?
Correct! Well done.
Incorrect.
The correct answer is B) User-space networking that bypasses the OS kernel for packet processing, reducing latency by avoiding system calls and context switches
B
Correct Answer
User-space networking that bypasses the OS kernel for packet processing, reducing latency by avoiding system calls and context switches
