Gigabit Ethernet Tap: Keeping an Eye on Your Network Traffic

Network traffic is the lifeblood of modern businesses. In our digital age, the speed, efficiency, and security of data transmission can directly affect an organization's success or failure. As such, network managers need the right tools to maintain the health of their networks. One such tool that can provide invaluable insights into network performance and assist in troubleshooting is the Gigabit Ethernet Tap.

What is a Gigabit Ethernet Tap?

A Gigabit Ethernet Tap (also known as a network Tap) is a hardware device which provides a way to access the data flowing across a computer network. A Tap (short for Test Access Point) is designed to monitor network traffic between two points in a network. It works by copying the data and sending it to monitoring devices such as a network analyzer, an intrusion detection system, or a network probe.

Network taps are an improvement over the traditional way of monitoring network traffic, which involves using a device's built-in port mirroring or spanning abilities. Taps provide a superior level of visibility, ensuring all network data passes through the Tap and can be thoroughly analyzed, including errors which might not be passed on by a traditional port mirror. Furthermore, taps are passive, meaning they don't introduce delays or alter the traffic in any way.

Benefits of Using a Gigabit Ethernet Tap

The use of a Gigabit Ethernet Tap in your network system comes with a wide array of benefits. Here are the top five benefits:

  • Reduced Network Downtime: Network downtime can be very costly for a business. A gigabit Ethernet tap allows for real-time troubleshooting and problem resolution, reducing network downtime.
  • Improved Network Security: By monitoring all traffic, including errors, a Gigabit Ethernet Tap can boost network security by identifying and alerting administrators to potential security threats.
  • Higher Quality of Service: By identifying issues that may not be immediately apparent but affect network performance such as slow network speeds or packet loss, a Gigabit Ethernet Tap can optimize the network to enable a higher Quality of Service (QoS).
  • Increased Network Visibility: Using a Gigabit Ethernet Tap, administrators can have total network visibility. This allows them to identify problem areas, bandwidth use, and traffic patterns to make informed decisions about network management.
  • Uninterrupted Network Operation: Since a Gigabit Ethernet Tap is a passive device, it allows for complete network traffic analysis without the risk of influencing the network's operation.

Choosing a Gigabit Ethernet Tap

When choosing a Gigabit Ethernet Tap, it's crucial to consider factors such as manageability, performance, compatibility, power options, and redundancy. You should also take into account the type of network you are managing. Copper network taps, for example, are ideal for 10/100/1000Base-T networks, while optical fiber taps are better suited for larger, more data-intensive networks.

It's also important to bear in mind your future network needs. Network growth can quickly outstrip the capacity of a network tap, and therefore it's prudent to select a tap that can deal with higher levels of network traffic than currently present.


Network monitoring is a vital component of any IT department's strategy. A Gigabit Ethernet Tap is a crucial tool for real-time monitoring, affording administrators greater control, enhanced security and allowing them to make more informed decisions about their network infrastructure. While there is an upfront cost to deploying network taps, the long-term benefits make it a sound investment for businesses of all sizes. Whether you are a small business owner or a network administrator in a large enterprise, it's worth considering a Gigabit Ethernet Tap to keep an eye on your network traffic and ensure optimal network performance.
