Kernel Bypass Technology
Kernel Bypass Technology is a method of network communication that allows an application to send and receive data directly through the network interface card, skipping the operating system's kernel. In standard networking, the kernel manages data packets, which introduces significant latency due to context switching and memory copying.
For high-frequency crypto trading, these microsecond delays are unacceptable. By mapping the network hardware directly into the application's memory space, traders can achieve much faster throughput and lower latency.
This technology is widely used in financial infrastructure to ensure that market data is received and orders are dispatched with maximum speed. It requires specialized drivers and often dedicated hardware support to function correctly.
While it increases the complexity of software development, it is a standard requirement for competitive market making. It effectively turns the server into a high-performance, specialized communication node.
