S409, CP handle link failure according to default processing mode.
In application scenarios as shown in Figure 1, interchanger 101 and two UP (i.e. above-mentioned first UP102 and above-mentioned second UP103 the Trunk across frame is realized before).Active and standby UP selection and user is completed by interacting between above-mentioned CP and two UP The synchronization of information table, user's routing table.The process is described in detail in step S301-S308.
Default processing mode during link failure is mainly introduced below.
As shown in figure 5, there is trunk between the UP (i.e. user plane) 502 and the 2nd UP 503 of interchanger 501 and the first LACP is interacted.Above-mentioned interchanger 501 can be perceived between above-mentioned first UP (i.e. user plane) 502 and the 2nd UP503 by LACP Link whether break down；Above-mentioned first UP502 and the 2nd UP503 can be perceived between interchanger 501 by LACP Whether link breaks down.Broken down when the first UP502 perceives it by LACP with the link before interchanger 501, first UP502 sends sensing results to CP (i.e. chain of command) 505 by openflow agreements.The CP505 is to above-mentioned first UP 502 Activestandby state switch over.When above-mentioned first UP502 is main UP, and above-mentioned 2nd UP503 is standby UP, the CP505 should 2nd UP503 is main UP from standby UP switchings, and above-mentioned first UP502 stops sending free ARP messages, above-mentioned 2nd UP503 Start to send free ARP messages, changed with informing that interchanger 501 is active and standby so that interchanger 401 newly reach the standard grade user please Message can is asked to be directly sent on the 2nd UP503 (i.e. main Up).
When the 2nd UP503 is switched into major state from stand-by state, above-mentioned CP505 needs to refresh on the 2nd UP503 User's routing table, ensure that data can be forwarded normally.Specifically, CP505 changes the cost values in user's routing table so that cost Value becomes big, and value maximum cost is 65535.
It should be noted that cost values are bigger, the priority of user's route is higher.
For interchanger, broken down when perceiving its link between the first UP502 by LACP, the exchange Machine will be switched to the 2nd UP503 from the first UP502, and the request message for the user that subsequently reaches the standard grade is sent on the 2nd UP503.
As shown in fig. 6, the first UP (user plane) 602 is main UP, the 2nd UP603 is standby UP.CP (i.e. chain of command) 605 can Whether the link by way of detection or between BFD perception CP605 and the first UP602 and the 2nd UP603 breaks down.On State the mode of detection and periodically send perception information to UP (including the first UP602 or the 2nd UP603) for CP605, when not connecing When receiving UP feedback message, so that it may determine that the link between CP505 and UP breaks down.UP (including the first UP602 or Two UP603) also can be by way of detection or BFD perceives whether its link between CP605 breaks down.
When above-mentioned CP605 is by way of above-mentioned detection or BFD determines that event occurs for its link between the first UP601 During barrier, above-mentioned 2nd UP603 is switched to major state by the CP605 from stand-by state, and the first UP stops sending free ARP reports Text, above-mentioned 2nd UP start to send free ARP messages, and so far the 2nd UP completes active and standby switching.
Because interchanger 601 can not perceive the switching of UP activestandby states, it can perceive interchanger by following two method The switching of UP activestandby states
First way：When the first UP602 is by way of above-mentioned detection or BFD determines it between above-mentioned CP 605 Link when breaking down, its Interface status being connected with interchanger is set to down by the first UP602.When interchanger detects As soon as the UP602 Interface status being connected with interchanger is down, perceive above-mentioned first UP602 and above-mentioned CP605 it Between link break down.Interchanger 601 and the 2nd UP603 protocol interactions across trunk, above-mentioned 2nd UP503 is identified as Main UP, and follow-up data are sent to the 2nd UP605.
The second way：Before link between the first UP602 and CP605 breaks down, the CP605 is by first UP602 priority parameters are sent to the 2nd UP603, and the 2nd UP603 priority parameters are sent to the first UP602.It is above-mentioned When CP605 perceives its link between above-mentioned first UP602 and broken down, the CP605 generates a priority parameters, and will The priority parameters are sent to the 2nd UP603, and the priority parameters are more than the first UP602 priority parameters.2nd UP603 connects After the priority parameters for receiving CP605 transmissions, the 2nd UP 603 is actively initiated and the protocol negotiation of interchanger, through consultation, 2nd UP603 identifications are main UP by the interchanger.By this negotiations process, the 2nd UP603 just completes the negotiation of preemptive type Journey.
By above two method, interchanger identifies the 2nd UP 603 for main UP, and follow-up data are sent to Two UP603.
As shown in fig. 7, the itself fails of the first UP 702, and the first UP 702 is main UP.It can pass through detection in CP705 Mode determine whether its link between the first UP702 or the 2nd UP703 breaks down.Specially CP705 is sent out to UP Send probe message.In detection cycle, above-mentioned CP705 does not receive UP (including the first UP702 or the 2nd UP703) feedbacks Message, then the CP705 perceive its link between UP (including the first UP702 or the 2nd UP703) and break down.
, should when above-mentioned CP705 perceives its link between the first UP702 by way of above-mentioned detection to break down 2nd UP703 is main state by CP 705 from stand-by state switching, and above-mentioned 2nd UP 703 starts to send free ARP reports Text.When the 2nd UP 703 is switched into major state from stand-by state, above-mentioned CP 705 needs the use refreshed on the 2nd UP 703 Family routing table, ensure that data can be forwarded normally.Specifically, CP 705 changes the cost values in user's routing table so that cost Value becomes big, and value maximum cost is 65535.
As shown in figure 8, event occurs for the link between the UP (i.e. user plane) 802 and the 2nd UP803 of interchanger 801 and the first Barrier.First UP802 perceives its link between interchanger according to LACP or detection mode and broken down, and second When UP803 perceives its link between interchanger according to LACP or detection mode and broken down, sent respectively to CP805 Sensing results.The CP determines that event occurs for the link of the first UP802 and the 2nd UP803 between interchanger according to the sensing results Barrier.Because the link between interchanger and the first UP802 and the 2nd UP803 breaks down, interchanger carries out main UP and standby UP selection, and actual data traffic can not be forwarded by UP and interchanger.Now, above-mentioned CP805 waits default After duration, start to delete user message table, user can normally reach the standard grade after preventing link-recovery.Because IPOE user is in link event Barrier can detect whether to go offline later, generate user's table after confirming to go offline, user accesses by crossing after link-recovery The mode can triggering of webpage is reached the standard grade.In order to prevent triggering from reaching the standard grade, above-mentioned CP805 temporarily preserves user profile backup table.
Alternatively, above-mentioned preset duration can be 1 minute, 2 minutes, 3 minutes, 5 minutes or other durations.
As shown in figure 9, the link of UP (including the first UP902 and the 2nd UP903) between CP905 all breaks down, use The flow at family still can be forwarded by UP and CR904 (i.e. router) to IP network.But during link failure, on State CP905 can not perceive the first UP902 and the 2nd UP903 state it is supreme because the User Agreement message newly reached the standard grade can not be sent CP905 is stated, it is impossible certainly to reach the standard grade, but user's (client) can be offline during link failure.
During link failure, offline message can not reach CP905 and will be dropped, and the user message table of user can be Remained on CP905 and UP (including the first UP 902 and the 2nd UP 903), and the related metering data amount of the user also can be by Lose, this can cause damage to the business of operator, while can also influence follow-up user and reach the standard grade.In this case, UP (space of caching can not be too for the offline request message that (including the first UP 902 and the 2nd UP 903) temporary cache user sends Greatly, if it exceeds space caches with regard to cover type), while the data traffic information used before user offline is recorded, pending fault link After recovery, then data traffic information sent to CP905 processing, for the user not changed during failure, link After fault recovery, corresponding data traffic is normally reported CP 905 i.e. by UP (including the first UP902 and the 2nd UP903) Can.
In order to mitigate the pressure of CP processing, the synchronization that a VM is used for full-time progress user message table is individually created on CP And route refresh, the backup of user profile is carried out between CP and UP (including the first UP and the 2nd UP) by Openflow agreements, Backup information includes：User authentication, mandate, charge information, QoS information and physical location information etc..Backup policy therein can To be to back up in realtime or batch backup.
It is pointed out that interacting between above-mentioned first UP and the 2nd UP and above-mentioned CP in above-mentioned steps S301-S309 Data are forwarded by CR.
As can be seen that in the scheme of the embodiment of the present invention, user plane UP sends priority parameters to chain of command CP；It is described UP receives the activestandby state mark that CP is sent, and the activestandby state is identified for indicating that the UP is the main UP or described standby Use UP；The UP identifies according to the activestandby state refreshes activestandby state；The UP to the CP send state refresh whether into Work(message.The priority parameters that above-mentioned CP is sent according to UP, UP activestandby state is determined, realize controls of the CP to UP.Work as generation During failure, UP can shift or solve failure according to the above method, ensure that the flow information of user on interchanger is uploaded to CP, real The complete double hot standby method in the case where CU is separated is showed.
