    摘要: An apparatus for and method of acquiring an address in a Dynamic Host Configuration Protocol (DHCP) environment in a wireless LAN. The method includes: sensing that a mobile node has moved from a first network to a second network; transmitting a frame requesting association with the second network to an access point managing the second network after sensing that the mobile node has moved from the first network to the second network; and receiving a message containing an address assigned to the mobile node from the access point having received the transmitted frame. Accordingly, the mobile node can promptly acquire an IP address without an additional request.

    摘要: A method, medium, and apparatus for assuring duplicate address detection. The method includes: determining whether a predetermined packet is related to a duplicate address detection, and if the packet is determined to be related to the duplicate address detection, modifying a source address of the predetermined packet to another predetermined address different from the source address. Proper duplicate address detection can be assured even in an environment where multicast packet filtering is based on a link layer source address that follows the IEEE 802.11 standard.

    摘要: Provided are a system and method for deleting tunneling when a correspondent node is connected to a mobile node that has moved to a different network. The system includes a domain name service server, a mobile node that moves to a different network, a domain name dynamic updating server, and a correspondent node. The domain name service server manages domain names and address of a plurality of mobile nodes. Once the domain name dynamic update server receives a message including the created address by the mobile node, the domain name dynamic update server updates domain name and address of the mobile node that are registered in the domain name service server using the domain name and address contained in the received message. The correspondent node connects to the domain name service server, obtains the updated address of the mobile node, and transmits a packet to the mobile node using the obtained address.

    摘要: A method and system for interconnecting an Internet protocol version 4 (IPv4) network and an Internet protocol version 6 (IPv6) network are provided. The system for interconnecting an IPv4 network and an IPv6 network includes IPv4 nodes, IPv6 nodes, and apparatuses for transmitting IP packets between the IPv4 nodes and the IPv6 nodes, wherein the apparatuses for transmitting IP packets share processing state information of the IP packets, using a predetermined message, to distribute their load of processing the IP packets. The IPv4-IPv6 interconnection method involves appropriately arranging NAT-PT apparatuses depending on the size of the networks such that packet processing speed and performance are improved over the use of a single NAT-PT apparatus.
