What is a Network Packet Broker (NPB)

A Network Packet Broker is an active device that directs selected raw data packets from network interfaces (typically via SPAN or Tap points) to specific network service and monitoring tools, performance management and security.

Basic packet manipulation capabilities include one network link, to one tool (one-to-one), one network link to multiple tools (one-to-many), multiple network links to one tool (many-to-one) and multiple network links to multiple tools (many-to-many).

To handle selected traffic, NPB also utilizes advanced filtering, stripping and other advanced packet capabilities.
