摘要： Flexible network policies might be enforced by (a) obtaining a flow of network packets, (b) determining a content characteristic by characterizing content of the flow using bit-stream level statistics, (c) determining content-independent flow characteristics, port-independent flow characteristics, and/or application header-independent flow characteristics, and (d) enforcing a policy on the flow using both (1) the determined content characteristic and the (2) determined content-independent flow characteristics, port-independent flow characteristics, and/or application header-independent flow characteristics.

摘要： Files can be reassembled from fragments by (a) accepting adjacency scores for each pair of fragments from a set of fragments, (b) identifying header fragments from the set of fragments, and (c) for each of the header fragments, (i) setting a current fragment to the identified header fragment, (ii) selecting, from any of the fragments not identified as a header fragment, a fragment with a best adjacency score with the current fragment, (iii) determining if the selected fragment has a better adjacency score with any of the other fragments not identified as a header than with the current fragment, (iv) if so, then (A) selecting another fragment, from any of the fragments not identified as a header fragment, a fragment with a next best adjacency score with the current fragment, and continuing, and otherwise (A) adding the selected fragment to a reassembly path started with the identified header fragment, and (B) setting the current fragment to the selected fragment, and continuing until the file is reconstructed.

摘要： A hierarchical data structure of digested payload information (e.g., information within a payload, or information spanning two or more payloads) allows a payload excerpt to be attributed to earlier network flow information. These compact data structures permit data storage reduction, while permitting efficient query processing with a low level of false positives. One example of such a compact data structure is a hierarchical Bloom filter. Different layers of the hierarchy may correspond to different block sizes.
