Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is done and to be elaborated.Traditional user's keep-alive mode is that SN handles user's keep-alive that whole AN hang down, and the different keep-alive mode of different user employing, and is in today that SN access customer number amount significantly promotes, apparent bigger to the pressure ratio of SN.The invention provides on SN equipment and adopt with a kind of keep-alive mode distributed keeping alive method at different PPP and DHCP user; by carrying out to reduce the keep-alive pressure of SN originally concentrating the mode of keep-alive to be distributed to AN at SN equipment, SN only needs and AN interactive user key message can be made and judges whether off-line of user.Wherein, user's key message is user's media interviews control (MediaAccess Control, MAC) address.Wherein, keep-alive is handled and to be comprised and carry out processed offline (deletion) when not handling with user's off-line when the user is online.
Fig. 2 illustrates the schematic flow sheet that the present invention is used for the method for keep-alive processing.See also Fig. 2, this method comprises:
201, the user who hangs under the AN inserts SN.
202, SN judges which user which AN has, and regularly this AN is hung down user's key message, by can with the mutual protocol apprizes AN of AN, wherein, user's key message can be MAC Address; Interaction protocol includes but not limited to two way translator system (Bidirectional ForwardingDetection, BFD) agreement, expansion BFD agreement, access node control (Access Node ControlProtocol, ANCP) agreement and/or Virtual Broadband Access Server (Virtual Broadband AccessServer, VBAS) agreement etc.
Wherein, SN and by and AN between the interaction protocol MAC information of informing the user that AN need check, this mode of informing can be that a kind of increment is informed, promptly informs AN at set intervals, and which user the user who inserts SN by this AN has increased or rolled off the production line and reduced which user.If user offline, SN tell that this user of AN need not to survey, then AN stops this scanning input.Certainly, also can adopt the mode of SN Real-time Notification AN when rolling off the production line on the unique user
202, SN judges whether AN has response, if having, then changes step 204 over to; If not then change step 207 over to.
204, AN is according to the user MAC that receives, scans in the MAC table of this AN whether comprise this MAC, if do not comprise in this user's a period of time of expression without any data message forwarding this user's off-line (promptly inactive).AN by with the mutual agreement of SN will this inactive user MAC inform SN.
205, after SN received the certain number of times of the sluggish information of certain MAC that AN informs, SN judged that this MAC user is inactive, and SN carries out not keep-alive to this user to be handled, and promptly deleted this user/carry out processed offline.
206, SN tells that this inactive user of AN need not to survey, and AN stops this user is detected.
If the request AN response timeout that 207 SN initiate, SN judge whether AN can reach and whether the following extension of AN customer flow is normal, thereby judge whether link failure between AN fault or AN and the SN.
When mutual message does not have response between AN and the SN, SN whether can reach by this AN and this AN under all users whether have flow to judge be the interaction protocol stack fault of AN, when AN can reach and insert interface flow that AN hangs down the user greater than a certain threshold values, judgement was the interaction protocol stack fault of AN.
If the flow that 208 AN can reach and insert AN greater than threshold value, is then thought under the AN not off-line (promptly active) of user; Otherwise, think that all users are inactive under the AN, force all user offlines under the access node apparatus.
SN can adopt the outer and interior dual mode keep-alive of band of band to the user, and keep-alive is meant and takies the keep-alive of subscriber line circuit bandwidth in the band, and wherein, subscriber line circuit is the access user sub-interface that refers to an access AN; Be with outer keep-alive to be meant and do not take the subscriber line circuit keep-alive, as long as AN and SN can reach, wherein, being with outer keep-alive is to adopt between SN and the AN to insert different circuit keep-alives with the user.
Adopt technical scheme of the present invention; a large amount of detection user pressure of SN are distributed to different AN; SN is as long as handle the unusual inactive user that AN reports; need not all normal and abnormal user all keep-alive count; effectively reduce the processing pressure of SN; avoided a large amount of keep-alives to handle and caused the SN processing too busy, the abnormal problem that may cause, the normal operation of maintaining network at SN.
Further; the session keepalive of having unified different user mode accesses (DHCP, PPPOE, L2TP); no matter be that the user of which kind of type is as long as the active existence that has flow MAC table on AN that this user MAC is all arranged makes SN to adopt different keepalive methods according to different users again.
Further; because whole keep-alive processing procedure is only mutual between SN and AN; therefore the keep-alive message only carries out between AN and SN, can not go downwards to subscriber's main station, thereby avoid the keep-alive message downlink to produce the safety problem that LAN subscriber is intercepted to subscriber's main station.
Further, can judge effectively that the reason that network failure produces is at user network or carrier network.User network often under the AN, on be carrier network.When AN judged that the user is unreachable, fault went out at user network, and when AN did not have response, fault may go out at carrier network.
