Abstract
A computer method and system for prioritizing network traffic flow to a protected computer network. Network traffic flowing from one or more external hosts to the protected computer network is intercepted and intercepted data packets are dropped if forwarding the intercepted data packet to the protected network would cause the value of the bandwidth of network traffic flow to the protected network to exceed a configured overall traffic bandwidth threshold value associated with the protected network. If not dropped, the intercepted data packet is analyzed to determine a classification type for the intercepted data packet based upon prescribed criteria wherein each classification type has an assigned classification bandwidth threshold value, wherein the classification bandwidth threshold value is less than the overall traffic bandwidth threshold value for the protected network. The intercepted data packet is dropped if forwarding the intercepted data packet would cause the value of the bandwidth of traffic flow to the protected network to exceed the bandwidth threshold value assigned to the determined classification type of the intercepted packets.
