emNet 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.

  • Low memory footprint
  • Seamless integration with the emNet TCP/IP stack
  • Client based NetBIOS name resolution



NetBIOS Backgrounds

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.



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.

emNet NetBIOS moduleApproximately 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.

emNet NetBIOS moduleApproximately 0.7 KByte

RAM Usage

emNet NetBIOS moduleApproximately 26 Bytes
