    摘要: Inventive embodiments relate to a method and an apparatus for tunneling service of an explicit multicast in a mobile IP network to forward multicast packets to plural mobile nodes with effect. When the apparatus providing the tunneling service for an explicit multicast in a mobile IP network receives a multicast packet from a correspondent node with a network, it extracts mobile nodes existing in a path for tunneling from among the plurality of mobile nodes. Also, after it creates an explicit multicast tunnel header having a destination address as a Co-Located Care-of Address (CL COA) of the mobile nodes existing in the path for tunneling, it tunnels a multicast packet that was encapsulated using the explicit multicast tunnel header to the mobile nodes.

    摘要: The present invention relates to a system and apparatus for tunneling service of explicit multicast, to efficiently transmit an explicit multicast of a packet to plural destinations. A tunnel ingress node is receives an explicit multicast packet from a sender terminal, which the explicit multicast packet has to be transmitted to plural addressee terminals. And, after the tunnel ingress node recognizes tunnel egress nodes using plural addresses terminal's address in the explicit multicast packet, it creates a tunnel header comprising transmission destinations based on the list of the recognized tunnel egress nodes. And then, the tunnel ingress node creates a tunnel packet encapsulated with the explicit multicast packet and the tunnel header, transmits the tunnel packet to the tunnel egress nodes. The tunnel egress nodes extract the tunnel header from the tunnel packet, and transmit the explicit multicasting packet to plural addressee terminals using the destination address of the tunnel header.

    摘要: Provided are a virtualization-supporting programmable platform device and a method of transferring a packet. The method includes, when a switch receives a packet including a destination sliver identifier (ID) and a virtual interface (VIF) ID, transferring, at the switch, the received packet to a sliver selected on the basis of the destination sliver ID, and transferring, at the sliver receiving the packet, the received packet to one of VIFs of the sliver on the basis of the VIF ID. Accordingly, a programmable platform or router supporting network virtualization can identify IDs of slivers, which are resources allocated to users in the future Internet, and VIFs connected to the respective slivers.

    摘要: Provided is a mobile IPv6 fast handovers method, which includes the steps of: a) if a mobile node is moved in a layer 2, receiving a modified RS message from a mobile node in the access router, b) detecting movement of the mobile node in a layer 3 in the access router, c) if the mobile node makes a movement in the layer 3, generating CoA of the mobile node in the access router; d) performing Duplicate Address Detection in the access router to inspect uniqueness of the generated CoA; and e) transmitting a modified RA message to the mobile node in the access router. The Fast Handovers method of the present research performs fast movement detection by using layer 2 information simply and efficiently for fast handover in the mobile IPv6 and generates CoA in the access router instead of the mobile node without operations of many additional messages.

    摘要: Provided is a method and apparatus for allocating a multicast connection identifier (MCID) for Internet protocol (IP) packet transmission over a portable Internet network and transmitting packets using the MCID. More specifically, there is provided a method of defining and allocating an MCID for transmitting an IP version 6 (IPv6) multicast packet over an IEEE 802.16/Wireless Broadband (WiBro) network and a process for transmitting an IP multicast packet of a base station (BS) using the MCID. The method of allocating is related to a method of automatically generating a connection identifier (CID) having 16 bits for packet transmission over the IEEE 802.16/WiBro network in order to transmit the IPv6 multicast packet. In this method, a scope value of the IPv6 multicast packet is added to the MCID. Therefore, multicast packets having an effective IPv6 scope such as a multicast packet in a link-local category, a multicast packet in a site-local category, and a multicast packet in a global category can be transmitted over the IEEE 802.16/WiBro network according to the scope of the multicast packet. Accordingly, when a new IPv6 scope is defined, the method can be naturally applied.
