Management of congestion level, in a computer-related context, is disclosed. Also disclosed is a system generating a plurality of computer network-related tables during system operation. A number of the tables are each separately indexed by a different index. The system includes at least one tangible computer-readable medium adapted to store, at each indexed location, a swap count providing an indication of the congestion level of the indexed location. The system also includes insert logic stored as instructions on the at least one medium for execution. When executed, the insert logic is operable to: i) insert, when a predetermined condition has been satisfied, a new entry by overwriting the current entry stored in the indexed location having the lowest swap count; and ii) update the swap counts in each of the indexed locations in a manner that maintains the total swap count at least substantially constant over time.
