  • receiving a packet from the stream of packets;

    associating a key with a field of the packet;

    applying an adaptive trie data structure, where each node of the adaptive trie data structure is associated with the key; and

    using via a processor the adaptive trie data structure to determine the hierarchical heavy hitter, wherein the hierarchical heavy hitter comprises a hierarchical aggregate of entities that account for a threshold portion of a total activity in the stream of packets.
