# RDMA (SMB Direct) Feature - Detailed Design Document

## 1. Overview

SMB Direct enables high-performance data transfer using Remote Direct Memory Access (RDMA) technology. This provides ultra-low latency and high bandwidth data transfer by bypassing the traditional TCP/IP stack and allowing direct memory-to-memory transfers between client and server.

## 2. Protocol Specification Reference

Auf diese Weise können andere Anwendungen und Clients diese JSON-Schemas direkt verwenden, bessere Tools zur Codegenerierung bereitstellen, usw.
