Abstract
A network element includes a data structure, a cache memory and circuitry. The data structure is configured to store multiple rules specifying processing of packets received from a communication network. The cache memory is configured to cache multiple rules including a subset of the rules stored in the data structure. Each rule that is cached in the cache memory has a respective cost value corresponding to a cost of retrieving the rule from the data structure. The circuitry is configured to receive one or more packets from the communication network, to process the received packets in accordance with one or more of the rules, by retrieving the rules from the cache memory when available, or from the data structure otherwise, to select a rule to be evicted from the cache memory, based on one or more respective cost values of the rules currently cached, and to evict the selected rule.
