# 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

- **MS-SMBD**: SMB2 Remote Direct Memory Access (RDMA) Transport Protocol

### Activer les en-têtes transférés par le proxy { #enable-proxy-forwarded-headers }

Vous pouvez démarrer FastAPI CLI avec l'option de CLI `--forwarded-allow-ips` et fournir les adresses IP à considérer comme fiables pour lire ces en‑têtes transférés.

Si vous la définissez à `--forwarded-allow-ips="*"`, elle fera confiance à toutes les IP entrantes.
