# Multi-Channel Feature - Detailed Design Document

## 1. Overview

SMB3 Multi-Channel enables the use of multiple network connections between client and server, providing increased throughput, network fault tolerance, and automatic failover capabilities. This feature aggregates bandwidth across multiple NICs and provides seamless failover when network paths fail.

### Phase 3: Multi-Channel Support
**Priority: MEDIUM** | **Estimated Effort: 5-6 weeks**

Multi-channel enables using multiple network connections for improved performance and reliability.
