Abstract:
PURPOSE: A multi-channel and multi-interface mesh router for assigning channel and a method thereof are provided to assign channel by calculating predicted traffic load. CONSTITUTION: A multi-channel and multi-interface mesh router(6) includes a storage unit(220) and a control unit(230). The storage unit stores the competition degree of each channel and a table including the number of adjacent node which uses the channel. The control unit determines the allocation channel about a static interface among the multi interface by considering the number of adjacent nodes or the stored competition degree.

PURPOSE: A network apparatus and method for supporting network virtualization are provided to dynamically supply two kinds of slice methods according to the selection of a user after differentiating the slice methods. CONSTITUTION: A software based virtualization unit(110) generates a virtualization slice based on other network devices and a software. A hardware based virtualization unit(120) generates a virtualization slice based on other network devices and a hardware. A virtualization control unit(130) activates the software based virtualization unit or hardware based virtualization unit based on the user information for requesting the generation of the virtualization slice. An open API(Application Programming Interface)(100) communicates with an external network including the open gateway.

CONSTITUTION: A communication terminal reads a code from an electronic tag(S200). A personalized service providing unit performs an authentication(S210). The personalized service providing device transmits the new code to a communication terminal(S220). A cod analyzing unit newly registers the new code and address information(S240). The personalized service providing device provides the information for privacy policy setting to the communication terminal(S255). The personalized service providing device sets a personal privacy policy(S260).
Abstract:
PURPOSE: A multi-path setting apparatus and a method thereof are provided to set up an independent path between interfaces classified to communications modes. CONSTITUTION: A message generating unit(410) generates a path request message for setting a path. A data transceiving unit(420) transmit the path request message. The data transceiving unit receives a path response message corresponding to the path request message. A path setup unit(430) sets up a plurality of paths capable of independent communication according to transceiving the path request message and path response message.

Abstract:
An automatic tunnel setting method using a RA message is provided to set a tunnel automatically using a RA message including an IPv4 address as an option even when an MN driving an MIP protocol moves to an IPv4 network in a combined IPv4/IPv6 environment, thereby keeping connection with an IPv6 network and securing MIP protocol operation. An automatic tunnel setting method comprises the following steps of: transceiving RS(Router Solicitation)/RA(Router Advertisement) messages(301); storing the tunnel termination information in an internal memory(302); checking whether an MN(Mobile Node) moves to an IPv4(Internet Protocol version4) network(303); performing handover to the IPv4 network(304); receiving an IPv4 tunnel end-point address from the IPv4 network(305); generating an IPv6-over-IPv4 tunnel automatically using the allocated address and the IPv4 tunnel end-point address as both end points of the tunnel(306); and communicating with the other node using an MIP6(Mobile Internet Protocol6) protocol(307).
Abstract:
A method and an apparatus for performing the configured tunneling based on the Internet protocol security are provided to solve the existing security risk problem, thereby performing the safe communication in an Internet service. A process for receiving a packet from an arbitrary host through an Internet protocol version 6 interface is performed(401). In the out-bounding process, a destination address and an approval header are added to a header area of the received packet so that an approval header packet is produced(403). The produced packet is transmitted to the destination address through the own Internet protocol version 4. In the in-bounding process(410), when the approval tunneling packet is received through the Internet protocol version 4 from another transmission host, the approval header is added to the received approval tunneling packet so that the packet is recovered to the original packet. The recovered packet is transmitted to the host connected with itself through the own Internet protocol version 6.
Abstract:
A method and a device for determining service provision with an RFID tag ID in an RFID system are provided to determine the service provision by using a tag, object, and item ID stored in the RFID tag to check whether the RFID tag is legally issued from the RFID system. A tag storing part(240) stores the tag IDs of the used. A first determiner(200) extracts at least one ID from the RFID tag and determines the interpretability of the extracted ID. A second determiner(220) determines the validity of the tag ID of the RFID tag when the tag ID identical with the extracted ID is found in the tag storing part if a determination result of the first determiner is positive. A service determiner(230) determines to provide a service for the RFID tag if the extracted ID is interpretable and the determination result of the second determiner is valid. The first determiner determines the interpretability of the item ID after reading the object ID and the item ID from the RFID tag, and checking the interpretability of the object ID.
