The motion sensor of the present invention includes a sensing unit for outputting a change signal corresponding to motion; a threshold level setting unit for changeably setting at least one changeable threshold level; and a comparator for performing a comparing operation based on the changeable threshold level and the change signal according to a threshold sensitivity corresponding to the changeable threshold level.
Abstract:
The present invention relates to a system and a method for managing harmful traffic filtering information. More specifically, if an edge router of a second autonomous system (AS), which is positioned at the rear end, detects harmful traffic and sets up traffic filtering information, the edge router transmits the traffic filtering information to a first AS at the front end, from which the harmful traffic was transmitted, through a border gateway protocol (BGP), and then the corresponding first AS applies the received traffic filtering information to a related router. Therefore, harmful traffic can be blocked in advance at the front end from which the harmful traffic is transmitted.

Abstract:
PURPOSE: A system and a method for operating a network based on network virtualization are provided to obtain the scalability and flexibility of a virtual network with a virtual network discrimination method based on a network service. CONSTITUTION: A network operating device comprises an operation interface part (210), a resource management part (220), a virtual network control part (230), a virtual network configuration specification database (240), and a virtual network profile database (250). The resource management part manages network resources. The virtual network control part forms multiple virtual networks discriminated by domain names and sets a representative virtual router of each virtual network. The virtual network control part sets representative routing information including the IP address of each representative virtual router in a virtual router contained in each virtual network. The virtual network configuration specification database stores the IP address of each representative virtual router corresponding to the domain names. The virtual network profile database stores the profile of each virtual network.

Abstract:
PURPOSE: A traffic management apparatus and a method thereof are provided to have a reduced security device traffic while having a short detection time. CONSTITUTION: An information collector (110) collects primary information about a flow. A controller (120) determines a state of traffic. The controller collects secondary information about the flow based on the determined traffic state. The controller determines whether there is an error of the flow based on the secondary information. A traffic mapper (130) drops the flow based on the determined traffic state. [Reference numerals] (110) Information collector; (120) Controller; (130) Traffic mapper; (AA) User; (BB) Server
Abstract:
PURPOSE: A router device for controlling traffic and recognizing an application and a method thereof are provided to perform a DPI(Deep Packet Inspection) function in a router, thereby eliminating necessity of separate DPI equipment. CONSTITUTION: A packet control unit(102) generates a flow block from a receiving packet. The packet control unit performs DPI of the receiving packet in the flow block. The packet control unit distinguishes an application related to the receiving packet. The packet control unit processes packets of the same flow, which is received through the packet receiving unit, by using application distinguishment information. A memory(104) stores a flow block which includes the application distinguishment information.

Abstract:
PURPOSE: A mobile router for a vehicle, mobile control platform, and method thereof are provided to offer an internet service to subscribers within the vehicle by utilizing all mobile back-born network interfaces which are able to be used in a mobile router for the vehicle. CONSTITUTION: An aggregation control unit(222) registers allocated IP(Internet Protocol) addresses to a mobile control platform. The aggregation control unit establishes the mobile control platform and IP layer link aggregation. When the IP layer link aggregation is established, a traffic distribution unit(224) allocates input packets to plural mobile back-born network interfaces according to each flow. A traffic collection unit(226) processes packet received by the mobile back-born network interfaces.
Abstract:
PURPOSE: An information exchange method between access gateways is provided to transfer AAA(Authentication, Authorization, Accounting) state information, a service profile, a QoS profile, and a user profile of a mobile terminal. CONSTITUTION: A first MAG(Mobile Access Gateway)(210) transmits a profile reply message including a user profile of MN(Mobile Node)(10), a QoS profile, service profile, and an authentication profile. A second MAG(220) receives a profile response message. The second MAG updates proxy binding information. The second MAG generates a bidirectional tunnel between LMAs(Local Mobile Anchor). The first MAG deletes the tunnel between LMAs according to the binding update.
