Port mirroring is a packet capture technique. It allows network packets seen on one port (or an entire VLAN) to be copied to another port, where packet traffic can be analyzed for security or other inspection purposes. In the age of constant and increasingly sophisticated cyberthreats, the demand for full packet traffic analysis is only rising.

• There are two ways to deploy port mirroring: 1) integrated port mirroring, often referred to as a Switched Port Analyzer (SPAN) port, and 2) external test access point (TAP) designed to mirror the traffic without impeding the flow of the production traffic.

• 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 taxing. 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.

• TAPs alleviate the processing load on the switch or router, but are very expensive.

• There is a third issue. When deployed in the cloud, users have no access to cloud provider switch infrastructure tools, and as such, are relegated to a TAP-based solution. Unfortunately, leading tap solutions require agents to be deployed, which introduces even greater deployment and operating costs.

• TNSR leverages Vector Packet Processing (VPP) to become a cloud gateway with built-in traffic monitoring
  - enable high volume port mirroring in software - without expensive, proprietary 'big-iron'.

• Deliver traffic to 3rd party security analysis/inspection tools at rates up to 100 Gbps - on premises or in the cloud - and beyond for a fraction of the cost of legacy solutions

• Additionally, TNSR enables flexible management - familiar CLI or Ansible®, SaltStack®, Puppet®, Chef™programmatic configuration and IT automated management via REST API - slashing traditional operating costs and speeding adds, moves and changes.

• Flexible deployment options - bare metal, VM, AWS cloud, Microsoft Azure cloud.

• Flexible licensing - perpetual or subscription.
