- [ ] Implement channel establishment protocol
- [ ] Add request distribution algorithm
- [ ] Create channel synchronization mechanism
- [ ] Implement channel failure detection
- [ ] Add automatic channel recovery
- [ ] Create channel performance monitoring

#### 3.3 Integration Points
- Modify `SmbTransportPool` for multiple connections per session
- Update `SmbSession` for multi-channel awareness
