Detailed Description

Simple module to test I3 multicast capabilities.

All nodes register the same identifier, then one node sends a message to that identifier. All participating nodes receive the packet .

Member Function Documentation

void I3Multicast::deliver ( I3Trigger &  trigger, I3IdentifierStack &  stack, cPacket *  msg  )

virtual

Delivers packets coming from I3 - should be overwritten by application.

Parameters

trigger	Application trigger to which the packet was sent
stack	Identifier stack passed from I3
msg	Arriving message

Reimplemented from I3BaseApp.

Definition at line 58 of file I3Multicast.cc.

{
    getParentModule()->bubble("Got a message!");
    delete msg;
}

void I3Multicast::handleTimerEvent ( cMessage *  msg )

virtual

Handles timers - should be overwritten by application.

Parameters

msg	Timer to be handled

Reimplemented from I3BaseApp.

Definition at line 64 of file I3Multicast.cc.

{
    if (msg == sendPacketTimer) {
        cPacket *cmsg = new cPacket("woot");
        I3Identifier id("whee");

        getParentModule()->bubble("Sending message!");
        sendPacket(id, cmsg);
        scheduleAt(simTime() + 20, sendPacketTimer);
    } else delete msg;
}

void I3Multicast::initializeApp ( int  stage )

Definition at line 48 of file I3Multicast.cc.

{
    sendPacketTimer = new cMessage("packet timer");
    scheduleAt(simTime() + 20, sendPacketTimer);

    I3Identifier identifier("whee");
    insertTrigger(identifier);
}
