NetBIOS
The emNet NetBIOS implementation is an optional extension which can be seamlessly integrated into your application. It combines a maximum of performance with a small memory footprint. The NetBIOS implementation allows an embedded system to resolve NetBIOS names in the local area network.
Overview
The Network Basic Input/Output System protocol is an API on top of the TCP/IP protocol, it provides a way of communication between separate computers within a local area network via the session layer.
Using NetBIOS, an emNet application can resolve a NetBIOS name to an IP address in the local area network.
Key features
- Low memory footprint
- Seamless integration with the emNet TCP/IP stack
- Client based NetBIOS name resolution
Requirements
The emNet NetBIOS implementation requires the emNet TCP/IP stack.
Resource usage
The ROM usage depends on the compiler options, the compiler version and the used CPU. The memory requirements of the NetBIOS module presented in the tables below have been measured on an ARM7 and a Cortex-M3 system. Details about the further configuration can be found in the sections of the specific example.
ROM Usage on an ARM7 System
The following resource usage has been measured on an ARM7 system using IAR Embedded Workbench V6.30.6, Thumb mode, no interwork, size optimization.
| Add-on | ROM |
|---|---|
| emNet NetBIOS module | Approximately 0.8 KByte |
ROM Usage on a Cortex-M3 System
The following resource usage has been measured on a Cortex-M3 system using IAR Embedded Workbench V6.30.6, size optimization.
| Add-on | ROM |
|---|---|
| emNet NetBIOS module | Approximately 0.7 KByte |
RAM Usage
| Add-on | ROM |
|---|---|
| emNet NetBIOS module | Approximately 26 Bytes |
