Introduction

The Accelerated IO (XLIO) library is a network-traffic accelerator, dynamically-linked user-space Linux library that transparently enhances the performance of socket-based networking-heavy applications over an Ethernet network. In addition, XLIO exposes standard socket APIs with kernel-bypass architecture, enabling a hardware-based direct copy between an application’s user-space memory and the network interface.

The XLIO library accelerates TCP and UDP socket applications by accelerating traffic from the user-space directly to the network interface card (NIC) without going through the kernel and the standard IP stack (kernel-bypass). XLIO increases overall traffic packet rate and improves latency and CPU utilization.
