SimpleNetworkLayer

Package: inet.networklayer.common

SimpleNetworkLayer

compound module

This module provides a simple network layer.

np : like INetworkProtocol

INetworkProtocol: This interface provides an abstraction for different network protocols.

Source:
np: <networkProtocolType> like INetworkProtocol {
    parameters:
        @display("p=85,95;q=queue");
    gates:
        lowerLayerIn[sizeof(parent.ifIn)];
        lowerLayerOut[sizeof(parent.ifOut)];
} echo : EchoProtocol

This module provides a mechanism to test network layer connectivity using echo request/response...

Source:
echo: EchoProtocol {
    parameters:
        @display("p=160,63");
}
