    摘要: A high-speed content inspection apparatus for minimizing system overhead is provided. The high-speed content inspection apparatus extracts content in unit of sub-pattern by inspecting a payload of a packet in units of sub-pattern, and extract target content by inspecting a correlation between the extracted sub-patterns. If a sub-pattern present at the end of a payload is smaller than a predetermined unit of a sub-pattern, position information of the sub-pattern at the end of the payload is rolled back and the correlation is inspected. Accordingly, without having to add another hardware or high-performance hardware, target content can be efficiently detected in real time.

    摘要: A distributed packet processing apparatus capable of distributing packet load across a plurality of packet processing engines is provided. The distributed packet processing apparatus includes a plurality of processing engines each configured to process allocated packets, a first tag generating unit configured to allocate an input packet to a processing engine, which has a processing engine index corresponding to a tag index for the input packet, among the plurality of processing engines, a second tag generating unit configured to calculate a tag index for an output packet, and an index conversion unit configure to convert the tag index for the output packet to one processing engine index among a plurality of processing indexes for the plurality of the processing engines and allocates the output packet to a processing engine having the one processing engine index such that loads are distributed among the plurality of processing engines.
