Network TAP

Network TAP


A network TAP is an external network device that creates a “copy” of the traffic for use by various monitoring devices. It allows traffic mirroring and is an intricate part of an organization's network stack. The network TAP device is introduced at a point in the path of the network that is felt should be observed, so that it can copy data packets and send them to a monitoring device. The network designer will decide where the significant points for the network TAPs should be placed in the network infrastructure, based on the reason for network interface observation: data gathering, analysis, general network monitoring (such as for saturation and latency), or more critical, such as for intrusion detection, etc.

Niagara Networks bypass switches have active TAP functionality built-in and have additional ports to feed the tapped traffc to reporting tools or a packet broker. Niagara Networks fixed and modular bypass switches offer active TAP functionality for speeds up to 100Gb. Both passive and active TAPs are offered, along with a wide range of supported connectors and fiber types.







  • Active TAPs: Based on an active switching configuration for generating a “copy” of the traffic. “Copy” traffic is regenerated and there is no loss of signal power. In the case of power failure, “copied” traffic may be lost, but network traffic flows uninterrupted. 
  • Passive TAPs: Based on optical coupler (splitter) so that the tapped network point and appliance are always connected. Passive TAPs don't need a power supply in order for them to work. It's 100% secure and invisible, with full transparency to IP, MAC addresses or any configurations and bandwidth rates up to 400Gbps.
