Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination due to congestion. This problem can result in excessive or unavailable bandwidth, network disruptions and even data corruption. How it’s monitored can differ from one provider to another, but common techniques include network traffic tracing, packet reordering, software checksums and timestamps. A detailed analysis of the error that caused the outage might show why the outage occurred, and what action should be taken to prevent it.

Some traffic monitoring solutions can’t be used to help solve the issue the application is experiencing, which could mean that it is caused by another component of the network. You’ll need to take action based on the evidence you have, and aim to establish the root cause of the issue.
For example, if you’re working on a networking task, you might need to try using some of the options listed below, or make use of what’s available within the network.
Network Trace Logging
Network trace logging (also known as network sniffing or application trace logging), involves examining every network packet that is transmitted to and from your machine and the network card that’s supporting it. Network trace log analysis can show the presence or absence of a problem, which can help identify and fix the problem. In some cases, trace logs can provide important insight to the problem.
In addition to gathering data, network trace logging can be extremely useful to developers who are working on an application that supports network trace logging. As we mentioned, network trace logging involves examining every network packet that is transmitted to and from your machine. If you’ve installed the Cisco IOS Software and are using a Cisco Catalyst 2860 Advanced switch, then you can use the Cisco Log Insight agent to collect trace logs of every packet that travels across your network. This can help to pinpoint an issue and fix it.
Traffic analysis is one of the most essential but underutilized tools available for troubleshooting network issues. It’s one of the few types of network tracing that is applicable to both IPv4 and IPv6, which can be especially helpful when troubleshooting issues over some of the older and smaller local area networks (LANs).
Traffic analysis is a tool that examines the flow of traffic on a network, to uncover the particular problems, such as traffic shaping, that could be causing the issues. Traffic analysis examines the behavior of a particular server or network device at the time of an issue. This can be particularly useful when investigating problems with web browsers, browser applications or other network applications. Traffic analysis can help you determine the impact of the problem to a particular computer or device, and suggest solutions to fix it.
