What is protocol analyzer

This is where conversation reports come into play. These conversation reports can be filtered and sorted to provide the maximum amount of data in a single report. When the network gets slow, instead of analyzing every application, you can take a look at the bandwidth usage for each protocol to help pinpoint irregular behavior, toxic applications, and IPs that drain valuable network bandwidth.

The applications can then be prioritized, and the required bandwidth can be set for business-critical applications and other application usage in the network. Obtaining such information from a networking device like routers or switches can be effortless when you configure your devices to export NetFlow packets.

With a meticulous report accompanied by drill-down options for more detailed stats, this feature allows you to see how efficiently the network bandwidth is being used. View the top applications in your network and ensure that the applications critical to your business get maximum priority. Hardware protocol analyzer : The hardware-based protocol analyzer uses hardware and software to capture the packets. Hardware-based protocol analyzers are used to debug hardware and complex SoC protocol interfaces.

The hardware-based protocol analyzer captures the packets of the interfaces for downstream analysis. Software protocol analyzer: Software-based protocol analyzer using only software to capture and analyze the protocol. These are commonly known as network analyzers. The software protocol analyzer is used for capture and analysis of LAN, Wireless network, etc. Fig 1. Development Time: By using a protocol analyzer the engineering team can cut down the development time significantly.

The engineering team can quickly capture the protocol packets and do the analysis to the complex protocols. The debug time can be cut down from months to few weeks.

Errors in manual Analysis: Most teams use manual capture and analysis of the protocol. Manual reporting and analysis may work for a small amount of data but as the complexity of capture increases, the error in reporting and analysis also increases. Using protocol analyzer inbuilt software the error in capture can be reduced to zero. Automation of work Environment : Many protocol analyzers support API integrations enabling the engineers to create fully automated test cases.

The automated test cases can be run as overnight regressions. In most cases, network administrators can simply enable a switched port analyzer SPAN to mirror network packets passing through the switch to a single port. In general terms, there are two main categories of protocol analyzers. Ad hoc protocol analysis tools are used to troubleshoot or analyze something specific and can be implemented for little or no cost with minimal planning or technical expertise necessary.

However, they are best for focused analysis a specific protocol or host and are not suitable for monitoring an entire network for an extended period. Enterprise analysis tools are more well suited for monitoring your entire corporate infrastructure around the clock, with options to provide a variety of alerts when your network is threatened. Security professionals occasionally need to break out a protocol analyzer to troubleshoot a problem on the network, such as authentication failures or to confirm sufficient encryption.

A variety of tools once competed for the attention of security and network professionals in the ad hoc protocol analysis arena, but WireShark formerly Ethereal has dominated the space to the point that many others including Microsoft Network Monitor were shelved. The two most critical features of an ad hoc analysis tool, and not coincidentally two key features that make WireShark so successful, is that it be both flexible and easy to use.

That removes cost as a barrier and provides a wealth of easily accessible training. A further benefit is that WireShark can ingest and analyze captured traffic from a number of other protocol analysis tools. That makes it easy to review network traffic during a specific time in history providing the traffic was being captured without breaking the budget. Enterprise protocol analysis differs from ad hoc analysis in key ways, most notably scale and duration. Ad hoc analysis typically occurs when you suspect a problem or need to evaluate a specific network segment, service or application.

Analyze protocol patterns over months, days, or minutes by drilling down into any network element.
