Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
First, the terms involved in the embodiments of the present invention will be briefly described:
MPU: a master control board card of network equipment with a distributed rack structure.
SFU: and (4) exchanging cards.
An LPU: and (4) a service board card.
The protection protocol is as follows: a protocol for maintaining backplane high speed channel link status.
SFU isolation: the SFU is no longer involved in forwarding across the service boards.
SFU isolation recovery: and enabling the isolated SFU to participate in forwarding across the service board card again.
Aiming at the current mainstream distributed rack network switching equipment, the service flow among all the service board cards is realized by forwarding of the switch card, the main control board card is used for controlling and managing the distributed network equipment, the switch card and the service board cards are connected through an internal link aggregation group, and each link aggregation group comprises a plurality of high-speed channels.
However, in a distributed network device formed by LPUs and SFUs, once multiple high-speed channels between the LPUs and the SFUs are completely blocked, the fault may cause packet loss or even flow interruption of traffic flow across LPU boards. Therefore, the distributed network device needs to process the link failure, and reduces the influence on the normal service flow.
In order to solve the above problem, embodiments of the present invention provide a fault processing method, an apparatus, and a distributed network device.
Fig. 1a is a schematic diagram of a distributed network device 100 according to an embodiment of the present invention. The distributed network device 100 may include a main control board card, a service board card connected to the main control board card, and a switch card, where the service board card is connected to at least one switch card through an internal link aggregation group, and each link aggregation group includes multiple high-speed channels.
It should be noted that the fault handling method and apparatus provided in the embodiment of the present invention are implemented based on the distributed network device 100.
Referring to fig. 2, fig. 2 is a flowchart of a fault handling method according to an embodiment of the present invention, where the method is described from the perspective of a master board of a distributed network device. The flow shown in fig. 2 will be described in detail below, and the method includes:
step S110: the master control board card obtains an isolation application initiated by the switch card, and the isolation application is initiated when the switch card detects that any service board card and all connecting channels between the switch cards are abnormal.
When the switch card SFU in the distributed network device sends a data packet to the service board LPU through the keep-alive protocol, the LPU can feed back the data packet to the SFU after receiving the data packet. When the SFU receives the feedback data packet, the characterization internal high-speed channel connection is normal, and when the feedback data packet cannot be received, the characterization internal high-speed channel connection is completely abnormal.
When the SFU detects that all internal high-speed channels connected with a certain service board LPU and the SFU are abnormal, because the keep-alive protocol is a bidirectional protocol, the LPU side also detects that all internal high-speed channels connected with the SFU are also abnormal.
As shown in FIG. 1b, the internal high speed path between SFU0 and LPU0 is completely failed. In this case, the SFU0 may initiate an isolation application to the master board MPU. After acquiring the isolation application, the MPU may determine whether the SFU0 initiating the isolation application needs to be isolated based on preset isolation conditions.
Step S120: and when the master control board card determines that the switch card meets the preset isolation condition, informing all the service board cards of stopping forwarding the cross-card data traffic to the switch card.
As mentioned in the foregoing, after acquiring the isolation application, the MPU may determine whether the SFU initiating the isolation application needs to be isolated based on a preset isolation condition.
The preset isolation condition may be:
besides the SFU0 initiating the isolation application, the distributed network device further includes at least one other switch card, for example, SFU1, SFU2 … …, and the like, and a connection channel in a normal connection state exists between the service board LPU0 having a complete failure of the internal high-speed channel between the service board LPU0 and the SFU0 and at least one other switch card, for example, a connection channel in a normal connection state exists between the LPU0 and the SFU 1. It should be noted that the normal connection channel herein does not necessarily mean that the connection states of all connection channels in the internal link aggregation group are normal, as long as there is at least one normal connection channel.
When the MPU determines that the distributed network device where the SFU0 and the SFU0 initiating the isolation application are located meets the preset isolation condition, that is, it is determined that the SFU0 meets the preset isolation condition, and then may notify all LPUs included in the distributed network device to stop forwarding the cross-card data traffic to the SFU 0.
When all the LPUs stop forwarding the cross-card data traffic to the SFU0, isolation of the SFU0 is completed, so that the SFU0 cannot participate in cross-card data traffic forwarding between the LPUs, and when cross-board service traffic forwarding is performed between the LPUs, the cross-board service traffic will not pass through the SFU0, thereby avoiding packet loss and even flow interruption of the service traffic across the LPUs when a link aggregation group between the SFU0 and the LPUs completely fails, and reducing influence on the cross-LPU forwarding traffic.
As an optional implementation, please refer to fig. 3, where the main control board MPU notifies all the service boards LPUs to stop forwarding the cross-card data traffic to the switch card SFU0, and after completing isolation of the SFU0, in order to recover the traffic forwarding across the service boards as soon as possible and minimize loss due to internal high-speed channel failure, the method may further include:
step S130: and when the master control board card determines that the switch card meets the isolation removing condition, informing all the service board cards to resume forwarding the cross-card data traffic to the switch card.
As an optional implementation manner, the isolation release condition may be:
and the connection channels between the isolated switch card SFU and all the LPUs are recovered to be normal.
In this embodiment, when the MPU determines that the connection channels between the previously isolated SFU0 and the LPU0 return to normal, and the connection channels with all LPUs are in a normal state, it may be determined that the SFU0 satisfies the isolation release condition.
As another optional implementation, the isolation release condition may be:
the isolated switch card SFU is pulled out or the service board card LPU at the opposite end of the isolated switch card SFU is pulled out.
When the SFU or the LPU is unplugged, the MPU may determine that the corresponding SFU is unplugged or determine that the corresponding LPU is unplugged, when the MPU may acquire a card unplugging interruption event generated by the corresponding SFU or the corresponding LPU.
In such an embodiment, when the MPU determines that the previously isolated SFU0 was unplugged, or when the MPU determines that the service card LPU0 on the opposite side of the previously isolated SFU0, it may be determined that the switch card SFU0 satisfies the isolation release condition.
As another alternative, the isolation release condition may be:
and the connection channels between the service board LPU at the opposite end of the previously isolated SFU and the rest switch cards in the distributed network equipment comprising the SFU are all disconnected.
In this embodiment, when the MPU determines that all connection channels between the LPU0 of the opposite end of the previously isolated SFU0 and the remaining switch cards in the distributed network device including SFU0 are disconnected, it may be determined that SFU0 satisfies the isolation release condition.
When the MPU determines that the isolated SFU0 satisfies the isolation release condition, the MPU may notify all LPUs to forward the cross-card data traffic to the SFU0, so that the SFU0 participates in the cross-card data traffic transmission and reception, and the loss caused by the internal high-speed channel failure is minimized.
In the fault handling method provided by the embodiment of the present invention, when a master control board in a distributed network device obtains an isolation application initiated by a switch card, if it is determined that the switch card satisfies a preset isolation condition, all service boards are notified to stop forwarding cross-card data traffic to the switch card, and isolation of the switch card is completed, so that the switch card cannot participate in cross-card data traffic forwarding between the service boards, and thus when inter-board service traffic forwarding is performed between the service boards, the switch card cannot be passed through, thereby avoiding packet loss and even flow break of service traffic of the cross-service boards when a link aggregation group between the switch card and the service boards completely fails, and reducing an influence on the flow forwarding of the cross-service boards.
