Abstract

A network device receives packets for one or more traffic flows to be sent into a network. The network device computes a flow identifier for each of the one or more traffic flows based on information contained in one or more headers of the packets for each of the one or more traffic flows and based on at least one value that is changed on an ongoing basis. The packets for each of the one or more traffic flows are encrypted to produce encrypted packets for each of the one or more traffic flows. An encapsulation is added to the encrypted packets for the one or more traffic flows. The flow identifier is included in a field of the encapsulation for a corresponding traffic flow.
