Description
Technical field
The present invention relates to PPPoE dial technology.
Background technology
At present, in network access technique field, the authentication techniques of employing mainly contain PPPoE, 802.1X, web authentication etc., wherein use the most general in the field of communications with PPPoE technology.
PPPoE dial-up access network is divided into two stages, discovery phase (Discoverystage) and PPP session stage (PPPSessionStage).Wherein:
(1) discovery phase is mainly divided into 4 steps, include main frame (host) and send initialized broadcast packet (PADI, PPPoEActiveDiscoveryInitiationpacket), one or more access server (AccessConcentrator) return response bag (PADO, PPPoEActiveDiscoveryOfferpacket), main frame sends the unicast packet (PADR of a session request again, PPPoEActiveDiscoveryRequestpacket), selected access server again loopback session confirms bag (PADS, PPPoEActiveDiscoverySession-confirmationpacket).
After completing these steps, the connection of a session (Session) will be set up in the two ends participating in certification, and know the ethernet mac address of pppoe session indications (SESSION_ID) corresponding to this connection and the other side, these parameters will define this PPPoESession uniquely and connect.After main frame receives this session confirmation (PADS) bag, main frame and access server enter PPP session stage by continuing.After this data send with mode of unicast, and in whole conversation procedure, PPPoESESSION_ID does not change.
After session connection is set up, main frame or access server at any time all can send a PPPoE and remove bag (PADT, PPPoEActiveDiscoveryTerminatepacket) to remove this session connection.After receiving PADT bag, any PPP information stream does not allow to have sent in this session connection.
(2) PPP session stage (PPPSessionstage), is mainly divided into link establishment (LinkEstablishmentPhase), Certificate Authority (AuthenticationPhase), network layer protocol to consult the link such as (Network-LayerProtocolPhase), link down (LinkTerminationPhase).Wherein, Certificate Authority is optional link.
Link establishment is that session both sides are by exchanging configuration data bag, receiving drive test to try and send confirmation bag and complete; For needing the link of certification (being generally needs in telecom operation), after link establishment, the Authentication and authorization of identity need be carried out immediately.Require the retry mechanism supporting certification, still identify after the trial exceeding certain number of times, this link will be removed.
After Certificate Authority passes through, network layer protocol (as IP, IPX or AppleTalk etc.) will by corresponding NCP(NetworkControlProtocol) choose and configure; Afterwards, corresponding Network layer Protocol Data bag just can be carried in this PPP connection.
But, in Certificate Authority link, usually user is needed to input username and password to carry out certification, such as, after user sets the username and password of PPPoE in the router, can not ensure it is correct, if input error, router can not dial-up success, and the dialing page is also shown as in connection always, any fault cues, not which results in user and does not know failure cause.
According to investigations, in the user using router but can not normally surf the Net, there is the user of 80% all because username and password inputs wrong causing.This problem is often difficult to discover, and user can spend several hours usually, and even the time of one day goes the problem of groping where to go out on earth, and to finally still can not enter net, cause a large amount of wastes of time and energy, and mood is irritated, depressed.
Most user even can think that router has fault, and application after-sale service, wastes the time of user oneself and router businessman, energy, disposal cost.
