Understanding Advanced Features in a Network Packet Broker

Network Packet Brokers (NPBs) have come a long way from their modest roots as data monitoring switches, though their intended application remains nearly the same.  The NPB is still primarily used as a device to maximize the performance of monitoring and security tools.
