A network sensor that features a data store and a packet processing engine. In communication with the data store, the packet processing engine comprises (1) a cache management logic and (2) deduplication logic. The cache management logic is configured to analyze packets to determine whether (a) a packet under analysis include duplicated data and (b) content of the packet is targeted for storage in a same continuous logical storage area as the duplicated data. The deduplication logic, when activated by the cache management logic, is configured to generate a deduplication reference for insertion into the packet prior to storage.

System, apparatus and method for managing redundancy elimination in packet storage during observation of data movement

A network sensor that features a data store and a packet processing engine. Communicatively coupled to the data store, the packet processing engine is configured to (i) generate a retention priority for at least a first flow within a first storage region of a plurality of storage regions and (ii) identify, in response to an eviction request, the priority of each of the plurality of storage regions. The priority of the first storage region is partially based on the retention priority associated with the first flow while the priority of a second storage region is based on retention priorities associated with flows stored within the second storage region. The packet processing engine also is configured to identify, through use of the retention priorities of the stored flows within the first storage region, which flows are to be retained and which flows are to be evicted.
