Why is network analysis important? Tab

Network analysis plays a critical role in any IT management strategy. Network analysis is all about ensuring the network is currently functional and will continue to be functional in the future. Effective networks support business processes at all levels, and slowdowns or failures on a network can immediately impact business productivity. Users must perform network analysis to identify bottlenecks, capacity issues, and more, to effectively troubleshoot current slowdowns and plan for future netwo

What does a network analyzer do? Tab

Network analyzers track network traffic levels and connectivity, providing valuable insights for users. One of the key features of network analyzer tools—sometimes called packet sniffers —is that copy data as it moves through network interfaces and make the data available for analysis by exporting it to a data flow collector . Because packet sniffers can collect a massive amount of data—including encoded administrative information—it’s essential to have a network analyzer tool capable of transla

How does a network analyzer work? Tab

Network analysis tools capture and analyze data traffic. These tools allow you to determine the specific portions of network traffic they monitor, meaning you can tailor monitoring based on feedback from end users. For instance, if employees across the organization report that a certain application is running slowly, then users can capture traffic at the application server’s network interface to determine if the server is truly the source of the problem. If the server responds normally, then mov

How does the network analysis tool work in NTA? Tab

One of NTA’s most useful features is its ability to analyze packet-level traffic across your network and wireless traffic. This allows users to track and monitor the applications, devices, and users putting the biggest drain on network performance. This information can be leveraged to troubleshoot issues with faulty hardware or users consuming an excessive amount of bandwidth. NTA also supports automatic alerts for when it detects unexpected or anomalous changes in network traffic, ensuring admi

Learn how network traffic analyzers work

NetFlow-enabled routers and switches collect IP traffic statistics on all interfaces and export the data as NetFlow records. A NetFlow data collector then processes the data for traffic analysis and presentation in an easy-to-understand format. NTA works in tandem with NetFlow-enabled devices by collecting traffic data, correlating it into a usable format, and presenting it to the user in a web-based interface designed for easy network traffic monitoring.

Network analysis refers to the processes involved in monitoring network traffic for the purposes of collecting information about traffic volume, activity, bandwidth, and different types of data flow. Network analysis can also be called network packet analysis or sniffing.

Here is a quick example: if the cloud- and web-based elements of your networking environment are experiencing slowdowns, one of the first things you’ll want to check is your Wi-Fi signal, as this could be a contributor to service outages. The processes of identifying and troubleshooting network-related issues are network analysis.

In addition to collecting information about data moving across the network, network analysis tools decode the data and display important metrics about it in an easy-to-parse user dashboard, allowing users to understand the current state of network activity at a glance.

Network analysis tools can assist with a variety of tasks, from general troubleshooting and monitoring wireless network availability and throughput to security countermeasures, such as detecting spyware and unauthorized, potentially malicious activity. Software applications with network analyzer functions can also be used to identify faulty hardware and applications that create bandwidth bottlenecks. Network analyzer software can even help determine which parts of the network have been targeted by a DDoS attack—and the source of the attack.

Network analyzer systems are a combination of hardware and software. Sometimes, a network analyzer is standalone hardware with software installed on it, while at other times, it is software installed on a computer as part of the network. The main differences between network analysis tools involve which parts of the network the tool focuses on, the number of protocols it can decode (and the quality of this process), the user interface, and the types of graphs or data analysis it can produce.
