The NETSCOUT® TAP family provides network monitoring devices with full and reliable access to network traffic. With the versatility of offering multiple options for link types and speeds, NETSCOUT TAPs can be placed on any strategic network link for comprehensive, always-on monitoring of the IT infrastructure.
A NETSCOUT TAP provides transparent access to network traffic. The TAP is invisible to devices on both ends of the link causing no disruption to data flows or protocol transactions - down to the lowest link-level control protocols.
NETSCOUT TAPs provide monitoring devices with an exact view of all packets on the monitored link, thereby enabling accurate packet analysis and capture. Compared to the use of a network device's traffic mirroring capabilities, a NETSCOUT TAP avoids any potential limitations in the device's architecture that might cause packet header loss/alteration or packet loss under heavy load.
Finally, NETSCOUT TAPs provide the most accurate view of application transaction times since there is minimal latency or latency variation added that might be introduced by a network device's mirroring process. This improves the accuracy of performance evaluation and modeling.
Conserves Switch and Router Ports
NETSCOUT TAPs allow the systems architect to devote network device ports to actual service usage, thereby extending the longevity of network devices at a given location and simplifying capacity planning for future growth.
Deployment Flexibility
NETSCOUT TAPs offer multiple form factors, monitored link densities, and media support for optimal versatility. The 1-link copper TAPs can be deployed in densities from 1 TAP up to 3 TAPs in a single rack unit (RU) - using the rackmount adapter kit. The 8-link copper TAP supports tapping of 8 full-duplex copper links in a single RU without the need for a rackmount kit.
The HD Fiber TAP chassis supports all HD fiber TAP module options in a single chassis. With up to 24 TAPs in a single rack unit, datacenter configuration can mix and match variable TAP modules at high densities. This flexibility supports evolving optical network conditions, from collections of homogenous links to those with various speeds and feeds. As networks upgrade, TAP modules can be easily added or swapped out.
Resilience to Power Failure
NETSCOUT fiber optic TAPs require no power; they are unaffected by power outages. NETSCOUT copper TAPs utilize redundant power supplies with nondisruptive, automatic failover in case of power loss or power supply failure. In case of total power loss, the copper TAPs feature rapid failover to passive, pass-through mode in order to minimize disruption to the monitored link. For maximizing availability, system architects can also utilize copper TAPs with built-in battery backup, which maintain active operation and avoids disruptions to the monitored link until TAP power is restored.
