Network Splitter (TAP) - a real helper for real-time monitoring of the network

In the increasingly developed network today, the network data monitoring has become an important means for enterprise users to solve network problems, to protect the network security. The Network Splitter (TAP) is one of the most popular methods of acquiring network data in real time. This tutorial will cover it in detail.

Network Splitter (TAP) basics

The Network Splitter (TAP) is a device that replicates Ethernet traffic, enabling real-time access to network traffic without interrupting normal network traffic. In use, the network splitter (TAP) should be connected in advance to the monitored link, where the network splitter (TAP) copies the network data in the monitored link to its other or more Port for different analysis tools for analysis.

The type of network splitter (TAP)

There are two main types of network splitter (TAP): active network splitter (TAP) and passive network splitter (TAP), passive network splitter (TAP) does not need electricity to run, the source network splitter (TAP) requires power to drive. Therefore, the active network splitter (TAP) is mainly used to transmit signals to the monitoring port of the link application, passive network splitter (TAP) in the enterprise data center in the simple monitoring applications are more common. In general, the use of passive network splitter (TAP) in the network is more extensive, in the use of it to analyze network data should pay attention to three points: 

1. network splitter (TAP) should be deployed to the monitored link to avoid the network breakdown in the process of monitoring;

2. The monitored link traffic does not exceed the line speed of the network splitter (TAP) port to prevent packet loss;

3. Use the combination of different network splitters (TAP) combination, you can achieve higher requirements of data monitoring.

The split ratio of the network splitter (TAP)

In the figure, the split ratio of the network splitter (TAP) is 30/70, what is the splitting ratio of the network splitter (TAP) The splitting ratio refers to the ratio of the power delivered to the monitoring device through the network splitter (TAP) and the ratio delivered to the terminal equipment, typically 50/50 and 30/70.


(TAP), for example, if the distance from the network splitter (TAP) to the monitoring device is short, you can select the network shunt with a split ratio of 30/70, and then select the network splitter (TAP) with the appropriate splitting ratio. (TAP) to ensure that the terminal equipment can receive higher quality signals and if the distance from the network splitter (TAP) to the monitoring device is long, a network splitter with a splitting ratio of 50/50 is required ( TAP) to ensure that the monitoring equipment and terminal equipment can receive the signal.

Conclusion

The Network Splitter (TAP) is a simple, effective and cost-effective network real-time monitoring device that helps people quickly analyze and monitor network conditions.
