  • Lossless real-time line-rate filtering using PCAP style filters and hardware assisted patricia trees
    Patent number: 8375031
    Abstract: A processor performs line-rate filtering using hardware-assisted Patricia trees. A PCAP-style filter is converted into a form that can be inserted into a Patricia tree. The PCAP filter expression is parsed and converted into disjunctive normal form (DNF). Each DNF clause of the filter is inserted into a Patricia tree. The DNF clauses are checked for overlaps and the overlapping clauses are combined when possible.
    Type: Grant
