Abstract: A method and a system for providing QOS based on flow in a IPv6(Internet Protocol version6) service network are provided to enable a network operating server to authenticate a QOS value according to each flow of a mobile terminal on a router capable of processing flow-based packets and provide the QOS value to all routers on a path, thereby providing end-to-end QOS in an IPv6-based BcN(Broadband convergence Network). A source terminal(202) transmits a flow service request message including flow information, QOS(Quality Of Service) requirements, to an AR(Access Router)(204). The AR extracts the flow information the received flow service request message(214). The AR requests a network operating server(206) to check the extracted flow information(218). The AR transmits the checked flow information to the source terminal(220). The source terminal transmits a flow information receiving Ack(Acknowledgement) message to the AR(222). The source terminal constructs a flow list of session information(224). The AR constructs the flow cache of a session(226).

Abstract: A method for constructing tunnel forwarding information in line cards of an IPv6 router is provided to offer an IPv6 packet tunneling function to rapidly convert IPv6 packets into IPv4 packets by receiving a forwarding information message having a tunnel interface, judging whether the received forwarding information message indicates a forwarding information addition request or a forwarding information deletion request, and adding or deleting tunnel information, IPv6 prefix information, and forwarding information respectively for a tunnel table, an IPv6 prefix table, and an IPv6 forwarding table. A line card in an IPv6 router receives a forwarding information message having a tunnel interface(601), and judges whether the received forwarding information message indicates an addition request or a deletion request for associated forwarding information(602). In case it is confirmed that the forwarding information message indicates a forwarding information addition request, the line card confirms whether tunnel information exists(603). If so, the line card increases the channel reference count by 1 and adds associated IPv6 prefix information and forwarding information respectively to an IPv6 prefix table and an IPv6 forwarding table(604,605). In case tunnel information doesn't exist, however, the line card adds associated tunnel information to a tunnel table(606). Then the line card adds associated IPv6 prefix information and forwarding information respectively to the IPv6 prefix table and the IPv6 forwarding table(605).
