IPv6 has the characteristic of plug and play, without any artificial interference, and a nodeAdd in network and can obtain IPv6 address prefix, DNS (abbreviation of DomainNameservice, territoryName service) network parameter such as address. Realize by two kinds of modes: by DHCPv6 (DynamicHostThe abbreviation of ConfigurationProtocolforIPv6) agreement has state automatically to configure; Pass through NDP(abbreviation of NeighborDiscoveryProtocol, Neighbor Discovery Protocol) agreement is carried out stateless and is automatically joinedPut.
BRAS (abbreviation of BroadbandRemoteAccessServer, Broadband Remote Access Server)A kind of IAD towards broad band network application. It is the bridge between broadband access network and backbone network, carriesFor basic access means and the management function of broadband access network. It is positioned at the edge of network, provides broadband to connectEnter service, realize converging and forwarding of multiple business, can meet different user to transmission capacity and bandwidth usageTherefore the requirement of rate is the nucleus equipment that broadband user accesses. First BRAS carries out for the user of accessCertification, certification is by allowing user to access broadband network, and authentification failure refusal user accesses broadband network.
The different authentication mode of BRAS access way is also different. BRAS is divided into PPPoX (BasedontheThe abbreviation of arbitrarytwolayerprotocolpointtopoint, the abbreviation of PointtoPointProtocol,Point-to-point based on any two-layer protocol) and IPoX (the IP access based on two-layer protocol, RP agreementCommon message. ) (X represents it can is that Ethernet Ethernet can be also ATM (AsynchronousThe abbreviation of TransferMode, asynchronous transfer mode), or other two-layer protocols). PPPoX accesses PPPItself provides authentication protocol agreement; IPoX access is according to the agreement different authentication mode difference of access, rightIn the DHCP of IPv4 (abbreviation of DynamicHostConfigurationProtocol, DynamicHost configurationAgreement) access provides WEB to authenticate and DHCP option authenticates.
The BRAS access of IPv6 is also divided into PPPoX and IPoX mode. The certification of PPPoX access is exactlyThe authentication protocol that ppp protocol own provides. DHCPv6 (having the state automatically to configure) mode of IPoX connectsEnter, WEB certification and option authentication mode (also calling off machine certification) can be provided; ND (the nothing of IPoXState configures automatically) mode accesses, and WEB authentication mode is provided.
WEB identifying procedure: first by network parameter distributorship agreement (DHCP, DHCPv6, ND(abbreviation of NeighborDiscoveryProtocol, neighbours find) distributed network parameters, the network of distributionIP address in parameter is limited, can only access the WEB server due to certification, can not access the Internet;In the time that user accesses WEB website, BRAS is redirected to the WEB clothes for authenticating the webpage of accessBusiness device; User's login username and password, authenticate to certification WEB server, and certification is by rear useThe limited IP address that family is distributed becomes non-limited, and user immediately can access the Internet, authentification failure userThe limited IP address of distributing is still limited, and user can not access the Internet.
Can adopt WEB mode to authenticate for personal computer terminal, this for TV set-top boxCan not carry out the terminal of WEB access and obviously can not carry out WEB certification. This application scenarios forDHCP and DHCPv6 agreement adopt option certification conventionally. Option certification refers to the association in log on parameterIn view message, insert the option that represents username and password information, before distribution network address parameter, useUsername and password in option goes certification, authentication success distributed network parameters, and authentification failure is distribution network notParameter, the terminal of authentification failure is owing to not having distributed network parameters can not access broadband network.
