IPvXAddress IPTrafGen::chooseDestAddr (   )  [protected, virtual]

{ int k = intrand(destAddresses.size()); return destAddresses[k]; }

void IPTrafGen::handleMessage (  cMessage *  msg  )  [protected, virtual]

Reimplemented from IPTrafSink. { if (msg->isSelfMessage()) { // send, then reschedule next sending sendPacket(); if (numSent<numPackets) scheduleAt(simTime()+(double)par("packetInterval"), msg); } else { // process incoming packet processPacket(msg); } if (ev.isGUI()) { char buf[40]; sprintf(buf, "rcvd: %d pks\nsent: %d pks", numReceived, numSent); displayString().setTagArg("t",0,buf); } }

void IPTrafGen::initialize (  int  stage  )  [protected, virtual]

{ // because of IPAddressResolver, we need to wait until interfaces are registered, // address auto-assignment takes place etc. if (stage!=3) return; IPTrafSink::initialize(); protocol = par("protocol"); msgByteLength = par("packetLength"); numPackets = par("numPackets"); simtime_t startTime = par("startTime"); const char *destAddrs = par("destAddresses"); cStringTokenizer tokenizer(destAddrs); const char *token; while ((token = tokenizer.nextToken())!=NULL) destAddresses.push_back(IPAddressResolver().resolve(token)); counter = 0; numSent = 0; WATCH(numSent); if (destAddresses.empty()) return; cMessage *timer = new cMessage("sendTimer"); scheduleAt(startTime, timer); }

virtual int IPTrafGen::numInitStages (   )  const [inline, protected, virtual]

{return 4;}

void IPTrafGen::sendPacket (   )  [protected, virtual]

{ char msgName[32]; sprintf(msgName,"appData-%d", counter++); cMessage *payload = new cMessage(msgName); payload->setByteLength(msgByteLength); IPvXAddress destAddr = chooseDestAddr(); if (!destAddr.isIPv6()) { // send to IPv4 IPControlInfo *controlInfo = new IPControlInfo(); controlInfo->setDestAddr(destAddr.get4()); controlInfo->setProtocol(protocol); payload->setControlInfo(controlInfo); EV << "Sending packet: "; printPacket(payload); send(payload, "to_ip"); } else { // send to IPv6 IPv6ControlInfo *controlInfo = new IPv6ControlInfo(); controlInfo->setDestAddr(destAddr.get6()); controlInfo->setProtocol(protocol); payload->setControlInfo(controlInfo); EV << "Sending packet: "; printPacket(payload); send(payload, "to_ipv6"); } numSent++; }
