Abstract
A packet forwarding network may include switches that forward network packets between end hosts. A monitoring network may be coupled to the forwarding network. A controller may control switches in the monitoring network to forward network packets tapped from the forwarding network to one or more packet recorders. The packet recorders may store the tapped packets and the controller may query the stored packets at a later time. The controller may analyze queried packets to monitor the operation of the packet forwarding network and, if desired, to display graphical visualizations associated with the packet forwarding network. If desired, the controller may instruct the packet recorders to replay the tapped packets to network visibility tools through the monitoring network. The controller may coordinate storage and query operations across multiple packet recorders using the monitoring network so that the packet storage capacity and recording rate may be scaled up over time.
