Embodiment
As stated in the Background Art, under aggregation scene, if aggregated links member port changes, send the scheme of BFD message according to existing clean culture, need to carry out a large amount of IPC communication, carry out the amendment of the corresponding setting of BFD session, expend a large amount of time, thereby cause BFD conversation, and and then traffic affecting stability.
In order to solve such problem, ensure the normal transmission of BFD, the present invention proposes a kind of BFD message transmitting method, can realize by member port and backup port thereof the multiport transmission of BFD message, ensure the stability of business.
As shown in Figure 1, be a kind of schematic flow sheet of BFD message transmitting method that the present invention proposes, specifically comprise the following steps:
Step S101, OAM equipment are determined the aggregation port group that sends BFD message.
The prerequisite of this step is to store in OAM equipment the information of corresponding aggregation port group, is described as follows:
First, OAM equipment, according to the actual conditions when pre-polymerization, is preserved the information of each aggregation port group, wherein, and the information that comprises all member ports that belong to each aggregation port group.
Then, OAM equipment need to be determined backup port for each member port, and records the corresponding relation between member port and backup port, and concrete method is:
In each aggregation port group, OAM equipment is that each member port distributes other more than one member ports that belong to same aggregation port group as backup port, and records the corresponding relation of each member port and backup port.
Hence one can see that, and member port and backup port are the member ports that all belongs to same aggregation port group.
In concrete enforcement scene, in order better to realize backup functionality, in the time determining backup port, should select the member port distant with the member port of backup port to be determined as backup port, ensure the isolation between member port and its backup port as far as possible, avoid between member port, can being subject to the related impact of fault in the situation that isolation is poor, is affected and make to back up effect.
Need to further be pointed out that, the port that can backup each other between different member ports, each member port also can be used as the backup port of multiple other member ports.Certainly, minimize in order to back up reliability optimization and fault coverage, can a different backup port be set for each member port.
Certainly, concrete backup port is really established rules and can be adjusted according to actual needs, and such variation does not affect protection scope of the present invention.
Step S102, OAM equipment, by the backup port of member port in aggregation port group and member port, send BFD message to opposite equip. respectively.
In concrete enforcement scene, the difference of the selective rule of the interface according to OAM equipment self to transmission BFD message, the specific implementation process of this step comprises following two kinds of situations:
Situation one, OAM equipment are specified the member port that sends BFD message.
In such cases, OAM equipment can directly select to send the member port of BFD message in aggregation port group, owing to preserving the information of corresponding backup port in OAM equipment, so, OAM equipment can directly inquire corresponding backup port, and corresponding processing procedure is as follows:
First, OAM equipment calculates hash value according to BFD message, selects to be matched with a member port of this hash value in the aggregation port group of the destination interface as transmission BFD message.
Then, OAM equipment is inquired about the backup port of selected member port in the corresponding relation of recorded member port and backup port.
Finally, OAM equipment sends to opposite equip. by BFD message by member port and backup port.
In actual application scenarios, above-mentioned operation can realize by the OAM CPU in OAM equipment.
Situation two, OAM equipment are not specified the member port that sends BFD message.
OAM equipment is handed down to BFD message after concrete member port, and determine the backup port of this member port according to corresponding strategy, thereby the mirror image of realizing BFD message sends, in concrete application scenarios, such strategy can be realized by this member port being configured to corresponding ACL (Access Control List, Access Control List (ACL)).
Be that OAM equipment calculates hash value according to BFD message, in aggregation port group (as the destination interface that sends BFD message), select to be matched with the member port of this hash value, send BFD message by selected member port to opposite equip., again according to the acl rule of configuration, BFD message mirror, to backup port, is sent to opposite equip. by backup port by BFD message.
For example, the matching condition of this acl rule is, the source port of BFD message and destination interface; The matching result of this acl rule is: above other member ports of same aggregation port group.
The information of the backup port in the matching result of this ACl rule can be determined according to the corresponding relation of the member port of storing in OAM CPU and backup port.
Concrete acl rule can be at device initialize, complete backup port determine or upgrade after be configured, concrete allocation position can be the chip at each member interface place, like this, each member port all can be carried out this rule in the time carrying out the transmission of BFD message, in the time that this member port sends BFD message, also can be mirrored in self backup port and send, the multiport of realizing same BFD message sends.
For the member port overcoming in aggregation port group changes the impact bringing, in the time that the member port in arbitrary aggregation port group changes, member port information in OAM renewal of the equipment aggregation port group, and according to the information of each member port included in current aggregation port group, adjust the backup port of each member port, and upgrade the corresponding relation of each member port and backup port.
Further, if application is the processing mode in above-mentioned situation two, complete after the renewal of corresponding corresponding relation, also need to adjust corresponding acl rule, ensure the normal realization that mirror image sends.
Compared with prior art, the present invention has the following advantages:
By applying technical scheme of the present invention, in aggregation port group, determine backup port for every each member port, and in the time carrying out the transmission of BFD message, the multiport of realizing BFD message by member port and backup port thereof sends, thereby, can not cause because sending the fault of port of BFD message or variation the interruption of BFD session, traffic affecting continuity and reliability, ensure the stability of business.
In order further to set forth technological thought of the present invention, existing in conjunction with concrete application scenarios, technical scheme of the present invention is described.
The present invention is by the method that adopts many member ports to send to the BFD message in aggregated links on OAM veneer, make in the time that the member port of aggregated links changes, BFD session is not interrupted, thereby ensure the continuation of customer service, like this, just make the BFD session of both sides remain connection, ensured the stability of business.
In the prior art, the BFD message that the OAM CPU of OAM equipment sends is unicast message, if the destination interface of this BFD message (is handed down to this destination interface by BFD message, send to opposite equip. by this destination interface) be aggregation port, will select one of them member port to send; Like this, if generation interruption is this member port, can cause BFD conversation.
For being very difficult for this to happen, technical scheme of the present invention makes OAM equipment send BFD message from two different member ports, like this, and whichsoever port generation link change, can not have influence on the normal transmission of BFD message, ensure that the BFD of opposite equip. detects unaffected.
Two member ports of above-mentioned transmission BFD message, are specially the member port of this BFD message of original transmission and the backup port of this member port.
In concrete enforcement scene, the selection deterministic process of corresponding backup port is realized by OAM CPU, be the information that OAM CPU stores corresponding aggregation port group, and according to the information of each member port included in aggregation port group, carry out the selection of corresponding backup port, concrete processing procedure is as follows:
Suppose that aggregation port group comprises 3 member ports (Port1, Port2, Port3), OAM CPU is to backup port of its each port assignment.For example: (Port1, Port3), (Port2, Port3), (Port3, Port1), wherein, Port3 is the backup port of Port1, and Port3 is the backup port of Port2, and Port1 is the backup port of Port3.
Taking distributed apparatus as example, the member device of aggregation port group and backup port can be positioned at the physical port of forwarding chip on different frames or plate, can be also the physical ports of the forwarding chip on same frame or plate.
In the implementation procedure of concrete technical scheme, if aggregation port group changes, OAM CPU need to, according to the situation of change of the member port in aggregation port, adjust the backup port of each member port.
OAM CPU completes after the selection or renewal process of backup port, and the corresponding relation between corresponding member port and backup port is stored.
As front, consider the difference of the selective rule of the interface of OAM equipment self to transmission BFD message, the present invention describes the process of transmitting of corresponding BFD message by specific embodiment respectively.
As shown in Figure 2, for the schematic flow sheet of the BFD message transmitting method under a kind of concrete application scenarios proposed by the invention, in this application scenarios, OAM equipment can be specified the member port that sends BFD message, and the concrete operation step of the method is as follows:
Step S201, on OAM CPU, safeguard the information of each aggregation port group, and each member port in aggregation port group is distributed to a backup port.
Step S202, in the time need to sending BFD message by aggregation port group at every turn, OAM CPU direct member port of selection in this aggregation port group, and inquire the backup port of this member port.
The selection of member port is according to the transmit port selective rule of BFD message default in concrete OAM CPU, and after this member port is determined, OAM CPU, from the backup information of the member port of this aggregation port group of its maintenance, inquires the backup port of this member port.
Step S203, OAM CPU send BFD message by this member port and backup port thereof.
Under this send mode, the port of giving out a contract for a project of specifying is aggregation port group, TGID that can aggregation port group finds corresponding member port, send to corresponding member port, and according to the backup information of safeguarding in OAM CPU, also can inquire the information of this backup port, therefore, OAM CPU directly issues BFD message to these two ports, makes two ports send this BFD message to opposite equip., and the multiport that can realize BFD message sends.
The BFD detection messages form of this transmission is simple, does not comprise the information such as Sequence, because BFD message is mainly expected the effect that BFD detects, so opposite equip. receives that many parts of same messages do not have problem yet.
Under this kind of application scenarios, if the member port in aggregation port group changes, OAM CPU directly upgrades corresponding aggregation port group information, and adjust the configuration information of corresponding backup port, selecting due to the transmit port of concrete BFD message is all to be undertaken by OAM CPU, therefore, OAM CPU can be at any time realizes the selection of the transmit port of corresponding BFD message according to the aggregation port group information after upgrading and backup port information, ensures the realization that multiport sends.
On the other hand, as shown in Figure 3, for the schematic flow sheet of the BFD message transmitting method under the concrete application scenarios of another kind proposed by the invention, in this application scenarios, OAM equipment can not be specified the member port that sends BFD message, and the concrete operation step of the method is as follows:
Step S301, on OAM CPU, safeguard the information of each aggregation port group, and each member port in aggregation port group is distributed to a backup port.
On step S302, the chip that connects at OAM CPU, configure acl rule.
For each member port configures corresponding ACL.Like this, all can acl rule of corresponding coupling to any one member port by this BFD message Hash, the BFD message mirror that this member port is sent is to backup port.Same, opposite equip. receives that many parts of same BFD messages can not affect the normal realization that BFD detects yet.
Need to further be pointed out that, after step S302 completes, if aggregation port group changes, return to execution step S301, carry out corresponding aggregation port group information, and the renewal of the corresponding relation of member port and backup port, further, for the setting in the acl rule having configured, also adjust accordingly.
Thus, complete the renewal of member port, backup port and corresponding acl rule, in the time that needs carry out BFD message, continued execution step S303, ensured the realization that BFD message multiport sends.
Step S303, in the time need to sending BFD message by aggregation port group at every turn, this BFD message is handed down to connected chip by 0AM CPU, the forwarding of tabling look-up.
Step S304, chip are tabled look-up and are determined and send the member port of this BFD message, and according to acl rule by this BFD message mirror to backup port.
Chip is through tabling look-up, and Hash determines the member port that sends this BFD message.
On the other hand, because this BFD message meets the matched rule of acl rule, so, chip by this BFD message mirror in the backup port of this member device.
The information of the backup port of this member port can be located in the corresponding acl rule of this member port, the information of this backup port is consistent with the backup information of preserving in OAM CPU.
Step S305, chip send to opposite equip. by this member port and backup port thereof respectively by this BFD message.
No matter apply above-mentioned which kind of mode, OAM CPU sends BFD message to more than two member port by aggregation port group to opposite equip..Like this, in the time that one of them port breaks down or when fault recovery, can not affect the transmission of the BFD message of local terminal.If the equipment of both sides is operation so all, the connectivity of BFD session can not be affected because of polymerization member's variation.
Compared with prior art, the present invention has the following advantages:
By applying technical scheme of the present invention, in aggregation port group, determine backup port for every each member port, and in the time carrying out the transmission of BFD message, the multiport of realizing BFD message by member port and backup port thereof sends, thereby, can not cause because sending the fault of port of BFD message or variation the interruption of BFD session, traffic affecting continuity and reliability, ensure the stability of business.
