网络丢包究竟如何解决（How to solve network packet loss exactly） Packet loss is in the use of Ping to our station for questioning, packets lost due to various reasons in the channel phenomenon. Ping uses the ICMP echo request and echo reply message. The ICMP echo request message is sent to the host or router to host a specific inquiry, must receive this message to the source host machine sends an ICMP echo reply message. This message is used to test whether the destination station inquiry can reach and understand the state. It is necessary to point out that Ping is an example of the direct use of the ICMP network layer, it is not through the transport layer of UDP or TCP. Reason of packet losses are mainly physical line failure, equipment failure, virus attack, routing information errors, we combined with the specific circumstances described. Physical line fault The network administrator found Wan line when the broken, this happens, there may be a line failure, may also be the cause of the user. In order to distinguish whether it is the fault line, you can do the following test. If the WAN line is through the router, you can log on to the router by extending Ping to the end of the router WAN interface to send large packets for testing. If the line is implemented by three layer switch, a computer is respectively connected to both ends of the line, and the IP address are respectively provided with a wide area network interface address of the end of the three layer routing switch, use the Ping to test computer -t address command. If the packet loss does not occur the test, the line operators to provide the line is good, cause the cause of the problem is that the user needs to find their own. If the above test packet phenomenon, then the fault line is provided by the supplier line caused by the need to contact with the supplier as soon as possible to solve the problem of line. There are a lot of packet loss caused by physical circuits, such as optical fiber jumper connection proble
