The library follows a layered architecture:

- **Context Layer**: `CIFSContext` interface provides the main entry point
- **Resource Layer**: `SmbResource` interface represents SMB network resources  
- **Protocol Layers**: Separate SMB1 (`jcifs.internal.smb1/`) and SMB2/3 (`jcifs.internal.smb2/`) implementations
- **Authentication**: NTLM, Kerberos, SPNEGO unified subsystem
- **Network Layer**: Transport abstraction, NetBIOS name resolution, session management

#### Application's calling thread

The application-layer must block on writing I/O. We can't return from a write until we've pushed its bytes onto the socket. Otherwise, if the write fails we are unable to deliver its IOException to the application. We would have told the application layer that the write succeeded, but it didn't!
