As with other service-providing processes in the QNX Neutrino RTOS, the networking services execute outside the kernel. Developers are presented with a single unified interface, regardless of the configuration and number of networks involved.
This architecture allows:
Our native network subsystem consists of the network manager executable (io-pkt-v4-hc or io-pkt-v6-hc), plus one or more shared library modules. These modules can include protocols (e.g., lsm-qnet.so) and drivers (e.g., devnp-speedo.so).
