TAPs Test Access Points
A complete corporate network health monitoring system requires lossless delivery of network traffic of interest to various probes, analyzers and security devices(IPS, IDS, DLP, etc.). One of the basic elements of such a system are test access point( TAP ) devices. These devices solve the problem of inadequate number of SPAN ports (SPAN-port contention) and their "loss" of packets (SPAN port oversubscription).
A TAP is a passive electronic or optical device designed to deliver a copy of network traffic to Network Packet Broker switches or diagnostic probes.
TAP is installed between any two network devices such as switches, routers or firewalls. The device does not introduce latency or affect intercepted network traffic. It has no MAC address, so it is immune to cyber attacks. The TAPs' design ensures uninterrupted network traffic even in the event of a device failure.
Depending on the functionality, we distinguish the following types of test access points:
Breakout "Normal " - this is the basic type of TAP. Its task is to provide a full copy of the network traffic, without any changes to the monitoring device.
Filtering/Filtration Test Access Point - its task is to provide a 100% copy of the network traffic to the diagnostic device. However, there are situations when the monitoring device needs only part of the information. A good example is Wireshark or VOIP monitoring solutions, which need only selected elements of network traffic.
Aggregating/regenerating (aggregating/regenerating) - allows you to connect multiple diagnostic devices testing a given network connection.
Replication TAP (Replication) - allows replication of network traffic from a single SPAN port to several monitoring devices, eliminating the problem of a limited number of SPAN ports.
TAP - media converter (Media conversion) - these devices are necessary when the diagnostic device has a different type of input port than the network. This type of TAPs allows to change the copper link to optical.
Bypass TAP - used to connect in-line diagnostic devices. Allows uninterrupted operation of the network, even in case of failure or periodic maintenance of the connected device (e.g. IPS).
We offer TAPs that support both 100M/1Gb copper and 1G/10G/40G/100G optical links - including all types of carriers with BiDi. For service purposes, all devices are also available in a portable version.
Stovaris offers products from two suppliers: Cubro and Profitap. As a result, we are able to offer customized configurations. Among other things, our suppliers offer modular solutions that allow us to pack a large number of TAPs into a 1U chassis.
