Optimize the performance of network analysis and security tools
The main function of a NPB is to filter specific network traffic to a specific monitoring tool, in order to optimize security and traffic flow. They are usually rack mounted and have copper or fiber inputs, and in many cases, both.
By maintaining a many-to-many (M:M) port mapping of network ports to monitoring ports, they can then direct network traffic more efficiently. This enables network engineers to filter on actionable data only, which allows the network tools to analyze much more efficiently.
