Abstract
A network filter is implemented so that filter terms that include intra-term OR conditions and converted to sub-terms that include only logical AND conditions. In one implementation, a device may include logic to receive a filter definition including one or more terms, at least some of the terms including logical OR conditions, that define how network traffic through the device is to be filtered, the logic expanding the one or more terms in the filter such that terms that contain logical OR conditions are expanded into a plurality of sub-terms that each contains only logical AND conditions. The device may further include a ternary content-addressable memory (TCAM) programmed to include a separate entry corresponding to each of the sub-terms.
