Passive fiber-optical network TAPs create perfect copies of all traffic seen on the network at full bandwidth. They require no power or management and do not actively interact with other components of the network.
Gigamon passive optical network TAP solutions include:
Active network TAP devices (also called ‘ethernet TAPs’) are used in networks where copper Ethernet or fiber optical technologies do not allow for passive TAPs. Just like passive TAPs, active network TAPs create perfect copies of all traffic at full bandwidth. However, active network TAPs require their own power source to regenerate signals. In the event of a power failure, active network TAPs include a battery backup to keep them up and running, sending an alert to indicate the failure. Copper active TAPs also have a relay that closes when the device loses power, thereby maintaining the network connection and minimizing traffic disruption.
Gigamon active network TAP solutions include:
Virtual network TAPs (vTAPs) are used in network function virtualization (NFV) and in private and public cloud infrastructures to gain access to East-West and North-South traffic within the hosting environment. Depending on the virtual machine or container technology in use, different tapping functions are available.
Gigamon offers four light-weight vTAP solutions for traffic acquisition within the GigaVUE Cloud Suite:
Key benefits include:
Bypass TAPs are used in copper and fiber Ethernet networks for supporting inline security, which redirects all network traffic passing between network devices to inline applications such as intrusion prevention systems (IPS), web application firewalls (WAF), email gateways (GW) or wide area network (WAN) optimization devices. A bypass TAP is typically a hardware device, inserted at a strategic point in the network — usually at a private or trusted network’s perimeter — to manage or secure all or specific data communications.
All bypass TAPs also have a relay that closes when it loses power, maintaining the network connection and performance while minimizing traffic disruption.
Gigamon bypass TAP solutions are an embedded capability within the GigaVUE HC Series of visibility nodes.
