Methods and systems for analyzing flows of communication packets. A front-end processor associates input packets with flows and forwards each flow to the appropriate unit, typically by querying a flow table that holds a respective classification for each active flow. In general, flows that are not yet classified are forwarded to the classification unit, and the resulting classification is entered in the flow table. Flows that are classified as requested for further analysis are forwarded to an appropriate flow analysis unit. Flows that are classified as not requested for analysis are not subjected to further processing, e.g., discarded or allowed to pass.

System and method for efficient classification and processing of network traffic

Methods and systems related to keyword searching processes. A list of keywords may be first represented by a set of short substrings. The substrings are selected such that an occurrence of a substring indicates a possible occurrence of one or more of the keywords. Input data may be initially pre-processed, so as to identify locations in the input data in which the substrings occur. Then, the identified locations are searched for occurrences of the actual keywords. The pre-processing scheme enables the keyword search process to search only in the identified locations of the substrings instead of over the entire input data.

Systems and methods for efficient keyword spotting in communication traffic

Methods and systems for managing the actions that are applied to packet flows by packet processing systems. A packet processing system maintains a flow table, i.e., a list of active flows and respective actions to be applied to the flows. The system classifies each incoming packet into a respective flow, and processes the packet in accordance with the action that is specified for this flow in the flow table. Typically, the system deletes a packet flow from the flow table when it becomes inactive, e.g., when no packets belonging to the flow arrive within a certain time-out period.
