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.

摘要： In a system for providing an IPTV service, if a multicast address of an IPTV channel received from a head-end is a multicast address requested by a mobile node through a tunnel, an end router confirms a care of address (CoA) of the mobile node corresponding to the multicast address of the IPTV channel, sets the multicast address in the first header of broadcasting traffic, sets the CoA of the mobile node in the second header of the broadcasting traffic, and then sends the broadcasting traffic.

摘要： Technology for forming a virtual private network (VPN) is provided. A VPN gateway that supports mobility with a connection node having a virtual home address (HoA) and a care of address (CoA) includes a mobility support unit, a data security unit, and a virtual address converter. When a packet is transferred from the connection node, the mobility support unit sustains a binding relationship between a home address (HoA) of the connection node and the changed CoA, and processes a mobility tunnel for the packet, thereby generating a first conversion packet. The data security unit performs a security test of the first conversion packet. The virtual address converter converts the HoA of the connection node, which is a source address of the first conversion packet in which the security test is complete, to a private network internal address that can be used in the VPN, thereby generating a second conversion packet.
