Abstract
Some embodiments of the invention provide a method for a first security controller that performs security operations on the packets that are transmitted within a network. The method of some embodiments receives a packet from a forwarding element in the network based on a decision made by a security agent that operates along with the forwarding element. When the first security controller stores a security rule for the packet, the method processes the packet according to the stored security rule. When the first security controller does not store a security rule for the packet, the method (i) determines that a second security controller stores a security rule for the packet based on a set of header values of the packet, and (ii) sends the packet to the second security controller for security processing according to the security rule for the packet stored on the second security controller.
