Chapter VII. WD-TOE

Introduction

Chelsio WD-TOE (Wire Direct-Transmission Control Protocol) with a user-space TCP stack
enables users to run their existing TCP socket applications unmodified.
It features software modules that enable direct wire access from user space to the Chelsio
network adapter with complete bypass of the kernel, which results in a low latency Ethernet
solution for high frequency trading and other delay-sensitive applications.
