Abstract
A method for classification includes storing in a TCAM classification rules comprising respective tags, each including an update bit. Data items are classified by extracting a respective key from each data item, appending an update-select bit to construct an extended key, and matching the extended key to one of the tags in the TCAM. In response to an instruction to atomically replace a group of existing rules in the TCAM with new rules, the update bit is unmasked and set to the first bit value in the group of the existing rules. The new rules are stored in the TCAM, with their update bit set to a second bit value. After storing the new rules in the TCAM, the update-select bit in the extended key of the received data items is set to the second bit value.
