It is crucial that this networked system operate as effectively as possible, because downtime is both costly and an inefficient use of available resources. Network applications require full availability without interruption or congestion.Īs the information systems in a company grow and develop, more networking devices are deployed, resulting in large physical ranges covered by the networked system. Computer networks today carry all kinds of data, voice, and video traffic. Yuri Gordienko, in Sniffer Pro Network Optimization and Troubleshooting Handbook, 2002 Understanding Network AnalysisĮlectronic distribution of information is becoming increasingly important, and the complexity of the data exchanged between systems is increasing at a rapid pace. A typical network analyzer understands many protocols, which enables it to display conversations taking place between hosts on a network. A network analyzer is a device that gives you a very good idea of what is happening on a network by allowing you to look at the actual data that travels over it, packet by packet. One of the best tools for performing network analysis is a network analyzer like Wireshark. Network analysis can be used to estimate the capacity of an existing network, look at performance characteristics, or plan for future applications and upgrades. Network and/or protocol analysis is a range of techniques that network engineers and technicians use to study the properties of networks, including connectivity, capacity, and performance. It is crucial that this networked system operates as effectively as possible, because downtime is both costly and an inefficient use of available resources. As the information systems in a company grow and develop, more networking devices are deployed, resulting in large physical ranges covered by the networked system. Network applications require full availability without interruption or congestion.
