### 6.3 Transport Layer Integration
```java
// In SmbTransport.java
private void handleIncomingMessage(ServerMessageBlock2 msg) {
    if (msg instanceof Smb2LeaseBreakNotification) {
        Smb2LeaseBreakNotification breakNotif = (Smb2LeaseBreakNotification) msg;
        

    }
}
```

### 6.3 Session Integration
```java
// In SmbSession.java
private PersistentHandleManager handleManager;

public SmbSession(CIFSContext context, SmbTransport transport) {
    // ... existing initialization ...
    
    if (context.getConfig().isUseDurableHandles()) {
        this.handleManager = new PersistentHandleManager(context);
    }
}
