What Is a Network Tap?

Network probe, including commonly used 2.5G, 10G, 40G, and test access port (TAP), is a hardware device that plugs directly into a network cable and sends a network communication To other equipment.

Network shunt

Network splitter, including commonly used 2.5G splitter, 10G splitter, 40G splitter and test access

Network taps are commonly used in networks

By inputting data to the network splitter, copying, converging, and filtering, and converting 10 Gigabit POS data to Gigabit through protocol conversion

1. Protocol conversion

As the mainstream Internet data communication interfaces used by ISPs are 40G POS, 10G POS / WAN / LAN, 2.5G POS,

Supports shunting according to L2-L7 application protocol.

Supports filtering according to the source IP, destination IP, source port, destination port, protocol, etc. with precise and masked 5-tuples.

Supports output load balancing and output homology and homology.

Supports filtering based on string character codes.

Supports session management. Forward the first N packets of each session. The N value can be specified by yourself.

Support for multiple users. Data packets that hit the same rule can be provided to a third party at the same time, or the data on the output interface can be mirrored and copied, ensuring data access for multiple application systems. ^[1]

Operators are concerned about network data protocol analysis, VOIP traffic, P2P traffic monitoring and control, monitoring illegal access of broadband users, intrusion detection system IDS, burst traffic such as attack and virus monitoring and prevention, network traffic audit and other fields. Its typical application mode is shown in the following figure: ^[1]
