Network Visibility: The Key to Proactive Network Management and Security

Posted on Jul 1, 2023 by

In the world of networking, it's crucial to have visibility into what's happening on your network. Without it, you risk not being able to detect issues, troubleshoot problems, or optimize performance. Network visibility is the ability to see and understand what's happening on your network in real-time, and it's essential for any organization that relies on their network to stay connected and productive. In this article, we'll explore what network visibility is and why it's so important.

What is Network Visibility?

Network visibility refers to the process of creating visual representations of networks, performance metrics, and data flows. It can also be defined as the ability to monitor and analyze network traffic to identify potential problems, security threats, and performance bottlenecks. This can be done with the following functions: topology graph, bilayer map, dependency graph, visualization chart. These capabilities allow you to view the physical and logical relationships between routers, switches, servers, and other devices to quickly identify and correct performance issues. Typically, in network topologies, NPB is adopted by IT staff to visualize the network and see what is happening on the network in real time, enabling proactive identification and resolution of problems before they affect end users.

Why is Network Visibility So Important?

Network visibility is important because it provides organizations with the ability to monitor and analyze network traffic. Here are a few reasons why network visibility is so important:

  • Faster troubleshooting: Using features like Layer 2 maps, business views, or performance graphs helps us quickly identify issues and pinpoint where they are in the network. Good network visibility software should also have an alarm system that notifies immediately when something goes wrong. This allows us to solve the problem in the shortest possible time.

  • Better visibility: The size of modern networks and the amount of accessible information make it difficult for large companies to visualize their networks, and topology maps can enhance the visibility of the entire network.

  • Efficient network planning: Network visibility tools help identify dormant devices in the network, which can help administrators for effective resource allocation.

  • Intuitive presentation: Network visibility can show a lot of information about complex networks in a simple, easy-to-understand way.

Advantages of NPB in Network Visibility

Network visibility solutions such as Network Packet Broker (NPB) can help enterprises and service providers maximize their return on investment (ROI) in network security and monitoring tools. Here are some of the advantages of using NPB for network visibility:

  • Centralized management: NPB provides a centralized platform for managing network traffic, which simplifies network monitoring and troubleshooting. Instead of having to manage multiple monitoring tools and devices, network administrators can manage everything from a single NPB.

  • Efficient use of monitoring tools: NPB can filter and aggregate network traffic, which helps to reduce the amount of traffic that is sent to monitoring tools. This reduces the load on monitoring tools, which can help to extend their lifespan and improve their performance.

  • Improved network security: NPB can be used to filter network traffic for security threats, such as malware, viruses, and other malicious traffic. This enables security teams to quickly identify and respond to security threats, improving overall network security.

  • Optimized network performance: NPB can be used to identify network congestion and other issues that can impact network performance. By directing traffic to the appropriate monitoring tools, NPB can help to optimize network performance and reduce downtime.

  • Flexibility: NPB can be customized to meet the specific needs of an organization. It can be configured to filter traffic based on specific criteria, such as IP addresses, protocols, and applications. This flexibility enables organizations to tailor their network monitoring to their specific needs.


Evaluating Your Specific Network Packet Broker Needs

NPB is an effective way to achieve network visibility, providing critical filtering, aggregation, load balancing, and security features. When evaluating NPB, it should consider factors such as capacity, filtering, aggregation, load balancing, security, and cost to choose the best solution for your specific needs. With the right network visibility tools in place, your organization can stay connected, productive, and secure.

FS NPB products have higher port density, which can improve scalability and meet a variety of traffic needs, such as FS T5850-48S6Q-R Network Packet Broker(NPB). It features 48 SFP+ (1/10 Gbps) and 6 QSFP+ ports (40 Gbps) providing aggregation, replication, filtering and load balancing in very high bandwidth port monitoring and analysis scenarios. Real-time network visibility capabilities can improve network security, optimize network traffic, and improve the performance and efficiency of network tools.


In short, network visibility is vital for effective network management and security. NPB solutions, such as FS NPB products, provide a centralized platform for managing network traffic, improving network security, and optimizing performance. Incorporating network visibility tools into a visibility architecture strategy can help protect valuable IT assets and ensure network reliability, security, and performance.
