1. A method of using a controller that controls client switches in a monitoring network having network interfaces that are coupled to a packet forwarding network and that receive tapped network packets from the packet forwarding network, the method comprising:
with the controller, receiving a packet recording policy that identifies a set of the tapped network packets to be recorded;
with the controller, generating network paths that forward the [ a ] set of tapped network packets from the network interfaces to a packet recorder through the client switches in the monitoring network for storage at the packet recorder;
with the controller, sending a packet request to the packet recorder that instructs the packet recorder to transmit a subset of the set of tapped network packets back into the monitoring network; and
with the controller, generating additional network paths that forward the subset of the set of tapped network packets from the packet recorder to a traffic analysis tool through the client switches in the monitoring network.
