Network Packet Loss Caused by configuring routing rings in Static Routing (1)

Routing RingNetwork Packet Loss

This is an actual case of analyzing the causes of a large number of packet loss on the network. The user's network packet loss is very serious, causing a lot of trouble to the user, we try to analyze the cause of packet loss through traffic analysis.

Network Environment

The user's network is a provincial network environment, including the provincial central LAN and cross-city Wan, and is connected to the national wide area network. The network topology is as follows:

Network exception description

This network packet loss is serious. If a local network sends packets to a local network or a national network through a local area network, only seven REPLY packets can be received for each 10 PING packets sent, and the packet loss rate is about 30%, network loss reports have a great impact on the running of some network applications. Applications are running slowly, and even some applications cannot run normally.

During this period, no exceptions were found in the operation of network devices and physical links of the LAN and WAN.

Network Packet Loss Analysis Methods

There are many possible causes of network packet loss, including link layer and network layer problems. network congestion is also a very likely cause of network packet loss. To analyze whether network packet loss is caused by network congestion, we use traffic analysis to analyze and locate the problem.

This is the basic introduction of packet loss. We will continue to introduce it as follows:
