Networking Architecture

As with other service-providing processes in QNX Neutrino, 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:

  • network drivers to be started and stopped dynamically
  • protocols to run together in any combination

Our native network subsystem consists of the network manager executable (io-pkt-v4, io-pkt-v4-hc, or io-pkt-v6-hc ), plus one or more shared library modules. These modules can include protocols and drivers (e.g.
