Ping 時間從 0.9 毫秒躍升至 11 到 28 毫秒之間

Ping 時間從 0.9 毫秒躍升至 11 到 28 毫秒之間

我有一台伺服器，另外 5 個設備都插入一個交換器。我可以以極低的 ping 時間（0.6 毫秒到 0.9 毫秒之間）對所有裝置進行 ping 操作。但是，突然之間，其中一台裝置的 ping 時間顯著增加（20 毫秒到 80 毫秒之間）。當 ping 速率惡化時，我們也看到裝置出現與連線不良（它是專業相機）一致的異常行為。

將裝置從交換器上拔下然後重新插入會將 ping 時間縮短至「正常」0.9 毫秒。過了一會兒，它又跳了起來。

我們無法識別與 ping 時間增加開始同時發生的任何外部事件。所有電纜均為 6 類結構。

它「聞起來」像某種電氣幹擾，但奇怪的是它工作一段時間正常，然後變壞，但當電纜斷開並重新連接時又恢復正常。

任何想法都會受到歡迎。謝謝！

（這是我的第一個問題，所以提前為這個問題的任何新手道歉）

感謝您的建議與評論。

看來是網路佈線問題。該電纜雖然品質很好，但與其他一些帶有特別嚴重干擾的電纜相鄰。電纜被重新佈線，問題就消失了。

再次感謝您的幫助和興趣。
