Expert Packet Conditioning for Scalable Visibility Network.

Packet Flow eXtender (PFX) is a software application enabling expert packet conditioning 
for service assurance and cybersecurity monitoring. The solution is built on the NETSCOUT InfiniStreamNG™ platform and framework leveraging patented technologies. As part of the nGenius Packet Flow System (PFS) portfolio, PFX integrates with NETSCOUT’s broad set of packet broker products to enable expert-level capabilities, such as NetFlow generation and IP tunnel termination.

Effortless Scalability

The PFX application runs on multiple InfiniStreamNG appliances and on several x86 server platforms, providing scalability on demand in a cost-effective manner. PFX connects to any type of network through TAP and SPAN ports, including IP tunneled connections for expert packet conditioning before forwarding desired traffic to the tool farms. PFX easily interconnects with a multitude of other PFS products from NETSCOUT or even with third-party packet brokers to form the desired solution configuration.

Flexibility and Choice

While organizations benefit from end-to-end visibility for the entire network, the challenge is to find a right-sized system that meets the needs at a particular location in the network. PFX offers a range of appliances and software options suitable for deploying in multiple topologies for different size installations from small to large enterprise and service provider data centers. To solve scalability and monitoring needs of very large environments, multiple PFX systems can be deployed to provide virtually unlimited scalability.
