The implementation step of switching according to the PPPoE link aggregation of the embodiment of the invention and protection as shown in Figure 5.
The first step (S402): the PPPoE access link of configuration BAS Broadband Access Server is supported the link polymerizable functional.
A1) configuration link polymerization interface: this interface is a virtual interface, is similar to loopback interface, and it represents link aggregation group, and its interface index is as the sign of link aggregation group;
A2) configuration place in circuit: configuration PPPoE place in circuit on the link aggregation interface, place in circuit can be Vlan, also can be the Ethernet interface of not being with Vlan, the place in circuit in aggregation group can be on same PPPoE business board, also can be on different PPPoE business boards.The link of polymerization will meet the regulation of IEEE 802.3ad: can only be same rate, and the ethernet link of full duplex;
A3) produce the MAC Address of aggregation group: this MAC Address is one of MAC Address on the Ethernet interface at PPPoE place in circuit place of polymerization, perhaps disposes this MAC Address separately.This MAC Address is as the source MAC of the message that sends on all links under this aggregation group.After guaranteeing link switchover, the former MAC Address of pppoe session is constant;
A4) configuration LACP (Link Aggregation Control Protocol, Link Aggregation Control Protocol): if need and the automatic configuration link polymerization of second line of a couplet equipment, then dispose the LACP agreement again, this step is optional, if do not dispose the LACP agreement, then need the link aggregation function of manual configuration second line of a couplet equipment.
Second step (S404): the switching equipment that configuration BAS Broadband Access Server user side connects, support the link polymerizable functional to reach the port that is connected with BAS Broadband Access Server.
B1) equipment of BAS Broadband Access Server user side connection need have the link aggregation function, it can be Ethernet switch, or the miscellaneous equipment with link aggregation function, the link aggregation function that they are realized will meet the link aggregation standard of IEEE 802.3ad;
B2) their configuration is with reference to their user's manual.
The 3rd step (S406): carry out pppoe session, the source MAC that sends message is the MAC Address of unified PPPoE link aggregation group, and the link that sends message be according to the output link in the link aggregation group of certain rule generation according to PPPoE Session Id (session identification).
The message distribution method: the link that sends message is according to the output link in the aggregated links of certain rule generation according to PPPoE Session Id.The characteristics of the rule here are:
C1) in link aggregation group, produce output link according to PPPoE Session Id;
C2) a given Session Id and link aggregation group, the output link of generation is determined, is unique;
C3) distribution of PPPoE Session Id is that the overall situation is unique, and perhaps every aggregation group is unique;

A concrete example is as follows: earlier activity chain way in PPPoE Session Id and the given link aggregation group is divided by, obtains their remainder.This remainder obtains corresponding link as the link index in the link aggregation group, and this link is exactly an output link, and from then on follow-up message all sends on the link.
In the 3rd step (S406), may further comprise the steps:
When d1) BAS Broadband Access Server receives PADI (PPPoE initiatively finds to start), be a PPPoE Session of user's preassignment Id, and this PPPoE Session Id be put in AC-Cookie (access concentrator sign) attribute of PADO (PPPoE initiatively finds to provide) message.The PADO message is selected output link according to top message distribution method when sending.Such Session Id pre-allocation process can guarantee that same pppoe session sends message on same link;
When d2) BAS Broadband Access Server receives PADR (PPPoE active discovery request), in the AC-Cookie attribute from the PADR message, extract PPPoE Session Id, in PADS (PPPoE initiatively finds to confirm) message, Session Id is distributed to the user.If do not receive the PADR message in a period of time, then the preallocated PPPoESession Id in front is reclaimed.The PADS message is selected output link according to top message distribution method when sending;
D3) carry out the ppp negotiation in pppoe session stage.The ppp negotiation message is selected output link according to top message distribution method when sending.
The 4th step (S408): after pppoe session is set up and to be finished, the forwarding information (transmitting as PPPoE) of pppoe session is synchronized on other PPPoE business board at this link aggregation group place.
According to top message distribution rules, though the forwarding information of pppoe session is synchronized on all PPPoE business boards at this aggregated links place, same pppoe session can only have an output link.Forwarding information synchronously, be that pppoe session can be switched to other link and get on when guaranteeing link occurs fault.
The 5th step (S410): the flow of periodic this pppoe session synchronously and session duration information are to other PPPoE business board at this link aggregation group place.
Synchronous flow and session duration information are to switch for the pppoe session protection to prepare.
The 6th step (S412): when the PPPoE link occurs fault, the link that breaks down is deleted from link aggregation group, produced the new output link of session according to the same quadrat method in the 3rd step again.
The 7th step (S414): if the business board at new output link place and former business board not on same business board, then the synchronizing information according to pppoe session generates new pppoe session entity on the business board at new output link place.
E1) judge that new output link and original output link are whether on same business board;
E2), then do not carry out any processing if on same business board;
E3), judge the whether normally operation of original business board again if on different disposable plates;
E4) if normal operation then is synchronized to this pppoe session state information (as link-state information) on the original business board on the new business board, otherwise does not carry out the information on the synchronous raw sheet;
E5) synchronizing information according to pppoe session generates new pppoe session entity on the business board at new output link place.
The 8th step (S416): when pppoe session finishes, on all PPPoE business boards at this aggregated links place, with the information deletion of this pppoe session.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
