# Witness Protocol Feature - Detailed Design Document

## 1. Overview

The SMB Witness Protocol enables rapid notification of resource changes in a clustered file server environment. It provides fast failover capabilities by allowing clients to register for notifications about server node availability, share movement, and other critical cluster events.

## 2. Protocol Specification Reference

Kurz bevor ich mich entschied, **FastAPI** zu erstellen, fand ich den **APIStar**-Server. Er hatte fast alles, was ich suchte, und ein tolles Design.
