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： There are provided a quality of service (QoS)-providing system and a method for providing quality of service for mobile nodes in the QoS-providing system. Under a network environment running a host-based network layer mobility protocol based on tunneling mechanism, the QoS-providing system may be useful to allow effective mobility supports by distributing binding information to the distributed nodes, in order to provide session-based quality of service for tunneled packets between the mobile nodes on the access nodes and distribute traffic load concentrated on the central mobility control platform as well. Also, the QoS-providing system according to one exemplary embodiment of the present invention may be useful to provide the function of hiding locations of mobile nodes since a care-of address of the mobile node is not transferred to a correspondent node and to automatically perform a route optimization procedure even when the mobile node does not directly perform a route optimization procedure.

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.
