Communication between network devices allowing each computer to know if the opposite end is still present and available. In a ping pong communication, the ping is the transmission of the packet to the opposite computer and the pong is the response from the other computer.
計算機設(shè)備在網(wǎng)絡(luò)通訊過程中允許每一臺電腦設(shè)備能夠知道與自己通信的設(shè)備是否在線戏仓、網(wǎng)絡(luò)是否可用由境。在ping-pong通信中袭灯，這個ping是將本臺計算機要發(fā)送的數(shù)據(jù)包發(fā)送到對面的計算機纱注，而pong就是對面的計算機對你這一發(fā)送的數(shù)據(jù)動作事件做出的一個響應(yīng)问欠。所謂的ping-pong通訊山孔，就類似于打乒乓球伏嗜，一方發(fā)球打過去坛悉，對方就會把球打回來做出回應(yīng)伐厌，如此的來來回回就表示事件還在進行中。
