    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: The invention relates to a method and an apparatus for controlling seamless handover between heterogeneous networks based on IPv6 over IPv4 tunneling. When IPv6 service is provided using tunneling in an IPv4 based network environment, handover of a mobile terminal between different networks is achieved through switching of an active tunnel and a standby tunnel, and thus handover between different networks is facilitated and data loss is prevented to secure continuity of service provided to the mobile terminal even when the mobile terminal hands over to a heterogeneous network.

    摘要: Provided is a method for configuring a control tunnel and a direct tunnel in an IPv4 network-based IPv6 service providing system. To provide IPv6 service, when a random request terminal receives a tunnel response message from a control server by using service information downloaded from a portal server at the time of initialization, the request terminal configures a control tunnel with the control server, and is registered to the control server. The request terminal transmits and receives a direct tunnel request message and a direct tunnel response message with a counterpart terminal by using its terminal information learned during the control tunnel configuration, i.e., network position information and status information, thereby configuring a direct tunnel. Thus, IPv6 communication is made through IPv4 based IPv6 tunneling, so that IPv6 application services that are not yet widely used can easily come into wide use. Also, only software change of each terminal and a control server is required without changing existing network equipment, so that a cost burden of a service provider can be minimized.

    摘要: A method of generating a flow label of an Internet Protocol version 6 (IPv6) is provided. A terminal generates a flow label to have four tuple information selected from five tuple information according to the provided method when the terminal creates a header. A network device classifies flows based on the four tuple information in the flow label generated according to the provided method. Since the flow label is generated to include only selected information and the network device analyzes less amount of information to classify the flows, the processing overhead is reduced. Also, since the terminal generates the flow label with selected essential information to classify the flows, the network device can finely classify the flows. Therefore, the differentiated service can be provided.
