Abstract
In one embodiment, an apparatus includes a processor for mapping packets associated with network flows to policy profiles independent of congestion level at the apparatus, and enforcing the policy profiles for the packets based on a congestion state. Packets associated with the same network flow are mapped to the same policy profile and at least some of the network flows are protected during network congestion. The apparatus further includes memory for storing the policy profiles. A method for protecting network flows during network congestion is also disclosed.
