Kernel Bypass

Kernel bypass is a technique that allows a network application to communicate directly with the network interface card, bypassing the operating system's networking stack. This eliminates the latency introduced by the kernel's context switching and buffer copying.

For HFT and crypto-trading systems, kernel bypass is essential for achieving microsecond-level performance. By taking control of the network packets at the hardware level, traders can react faster to market events.

It is a sophisticated optimization that requires specialized network cards and software drivers. It is a hallmark of ultra-low-latency infrastructure.
