    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 packet scheduling method and apparatus which allows multiple flows that require data transmission to the same output port of a network device such as a router to fairly share bandwidth. The packet scheduling method includes calculating an expected time of arrival of a (k+1)-th packet subsequent to a currently input k-th packet of individual flows by use of bandwidth allocated fairly to each of the flows and a length of the k-th packet; in response to the arrival of the (k+1)-th packet, comparing the expected time of arrival of the (k+1)-th packet to an actual time of arrival of the (k+1)-th packet; and scheduling the (k+1)-th packet of each flow according to the comparison result.
