Package: inet.emulation.networklayer.ipv4

ExtIpv4Socket

simple module

This module provides a bidirectional connection to an IPv4 socket of the host computer which is running the simulation. It writes the packets arrived on 'upperLayerIn' gate to the specified real socket, and sends out packets arrived from the real socket on 'upperLayerOut' gate.
