Abstract
A packet forwarding network may include switches that perform network forwarding operations to forward network traffic between end hosts that are coupled to the packet forwarding network. An analysis network that is controlled by a controller may be coupled to the packet forwarding network. The analysis network and the packet forwarding network may overlap. Switches such as hybrid switches in the overlapping network portions may be controlled by the controller to copy network packets without interfering with the network forwarding operations of the packet forwarding network. The analysis network may include a central portion to which analysis tools are coupled and one or more isolated portions. The controller may control the client switches of the central portion and the isolated portions to establish tunneling paths through the forwarding network.
