Abstract
The present invention is directed to a facility for classifying network packets. The classified network packets each contain a source address, a source port number, a destination address, and a destination port number. The facility first sums the source address, the source port number, the destination address, and the destination port number contained by the packet. The facility then determines the modulo remainder of the sum over a constant predetermined value. The facility uses the determined modulo remainder to classify the packet into a class of packets predicted to relate to the same network session.
