測量包丟失的ping-C++

Question

我需要用C++編寫代碼來測量ping的丟包率 - 丟包率。 我看到IPHLPAPI庫在RTT上有很多統計信息，但沒有丟包。

如果有人知道這件事，它會很棒！

謝謝。

當涉及到網絡時，您可以使用POCO庫，它比ACE更小（ALOT小於boost），並且比ACE更具可讀性。

下面是一個使用ICMPClient 一個ping程序的源代碼，你會發現它在POCO_BASE/NET /例子/平/ src目錄

您可以刪除記錄器/幫助的東西，使源位使用OnReply/OnError/OnEnd來計算丟包率

您發送4個數據包.... 3個數據包返回（OnReply）數據包丟失= 1-3/4 = 25％。
