    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.

    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 traffic analysis and flow-based dynamic access control system and method. The flow-based dynamic access control system for controlling a user's access to an internal communication network through an external communication network includes an access control unit operating in an access control mode in which traffic received from a user is basically blocked, generating state management information of a flow, which is received from the user, based on a specified packet of the flow, and verifying whether access of the flow to the internal communication network is a normal access. As a proactive defense concept of allowing only normal users to access an internal network, a method of blocking attacks from a system contaminated by a worm virus, detecting a cyber attack on a certain system in advance and automatically avoiding the cyber attack, and guaranteeing the quality of normal traffic even under cyber attacks without performance degradation of the internal network is provided.
