Abstract
A network monitoring device includes a data structure for maintaining information about endpoints involved in network flows. Each endpoint, either a source or a destination for a network flow, has information maintained in a modified binary trie, having a branch for each bit of the source or destination address, but with interior nodes having only a single child node elided. A pruning thread is given a limited amount of time for operation, with the effect that the data structure is maintained available for use except for only that limited amount of time. In the event that the pruning thread is unable to prune the entire data structure, it maintains a marker indicating where last it left off, and returns to that location in the data structure at a later pruning operation.
