2nd day of tracing INET6: Application/PingAPP
Define_Module (PingApp); 模組名稱是 PingApp
PingApp::initialize()
- 讀入 omnetpp.ini 中設定的參數.
- 在 TKenv 中監視
- sendSeqNo
- expectedReplySeqNo
- dropCount
- outOfOrderArrivalCount 這幾個結果 PingApp::handleMessage (cMessage *msg)
if (msg->isSelfMessage ()) 若訊息來自本身節點
destAddr = IPAddressResolver ().resolve (par ("destAddr")); 解析目的位址設定
來自其他節點則啟動回覆機制
processPingResponse(check_and_cast<pingpayload>(msg));
void PingApp::sendPing()
PingPayload msg = new PingPayload (name); 新增封包，接著下面照著宣告的格式填入對應的值 msg->setLength (8packetSize); //? 封包裡沒宣告
sendToICMP (msg, destAddr, srcAddr, hopLimit); 把訊息送到 ICMP 裡
PingApp::scheduleNextPing(cMessage *timer)
simtime_t nextPing = simTime () + intervalp->doubleValue (); 模擬時間加上間隔時間
void PingApp::sendToICMP (cMessage *msg, const IPvXAddress& destAddr, const IPvXAddress& srcAddr, int hopLimit) 判斷送出 v4/v6 icmp 格式封包
void PingApp::processPingResponse (PingPayload *msg)
收到 ICMP 封包，判斷</pingpayload> v4/v6 並<pingpayload>處理
</pingpayload>
