In a recent webcast, we discussed performance management and what to view when you check your statistics. The worst case is to use network utilization as a measure of network health. There are other more valuable statistics. Utilization is very important, but it is only a small part of the network health status. There

TCP: Transmission Control Protocol SYN: Request signal ACK: controlled command for acknowledgmentUDP: User Datagram ProtocolUDP belongs to a TIP/IP protocol family1. Turn on network port statusNetstat is a console command and is a very useful tool for monitoring TCP/IP networks, which can display routing tables, actual network connections, and status information

In Windows, you can use the ping command in CMD to detect network connection conditions, as follows:When the network connection is normal:When the network is not connected:In Java, you can call the ping command to determine whether the network is connected properly:Package Module.system.common;import Java.io.bufferedre

In our work, we often need to use the network and check the network status is essential. This is a tool class for checking the current network status. It can be directly pasted in the past: Package COM. todoo. android. app. utils; import java.net. inetaddress; import java.n

You may often encounter various router problems when working on network engineering. However, in addition to the configuration of a router, a more common method is to view network faults through the router port status. The following is a summary of my experience and I hope it will be useful to you. Check the status of
