Port Mirror

On-Premises Port Mirror

There are two traditional methods of deploying port mirroring on-premises.

The first is Integrated Port Mirroring, often referred to as a Switched Port Analyzer (SPAN) port. The challenge with SPAN ports is there is a limited number available on any given switch or router; and when running at high bandwidth rates, they can be an unwanted tax on the CPU. If processing tradeoffs are required when a switch or router comes under load, the port mirror is the first to be starved, meaning important traffic is not copied and sent to analyzers.

The second is an external test access point (TAP) - a hardware device inserted at a specific point in the network to monitor data. TAPs alleviate the processing load on the switch or router, but are very expensive.

Neither approach is ideal.

Cloud Port Mirror

As the need for traffic monitoring shifts from on-premises to the cloud, network operators do not have access to cloud provider switch infrastructure tools. Integrated Port Monitoring is, therefore, not an option in the cloud - forcing the user to the traditional TAP approach.

Leading cloud TAP solutions require agents to be deployed, which introduces unwanted complexity and additional operating costs.

Solution

TNSR^® software acts as a "software TAP" with built-in traffic monitoring - enable high volume traffic copying with ease - on-premises or in the cloud.

High throughput. Easy scalability. Low cost.

Key capabilities include:

• • • • High-speed traffic copies. Deliver traffic to 3rd party security analysis/inspection tools at rates up to 100 Gbps - on premises or in the cloud.
      • Low cost. Fraction of the price of legacy solutions.
      • Flexible management. Familiar CLI or automated management via REST API.
      • Flexible on-premises deployment options. Bare metal or VM.
      • Cloud Ready. Available on Amazon AWS and Microsoft Azure.
