Abstract
In one aspect, a disclosed method of processing a network packet received by an edge device from a client in a data processing network includes determining a priority category of the network packet when the priority category is indicative of a priority associated with the packet. The method further includes determining a value of a traffic state parameter. The traffic state parameter indicates a level of traffic activity in a backbone network to which the edge device is connected. A traffic policy is then determined that is applicable to the level of traffic activity and the priority category of the network packet. The network packet is then blocked from traversing or permitted to traverse the network packet edge device based on the determined traffic policy. Determining the priority category may include determining a transport protocol port number of the network packet.
