Description

Restarting method and device of switch, storage medium and electronic device

Technical Field

The embodiment of the application relates to the field of computers, in particular to a restarting method and device of a switch, a storage medium and an electronic device.

Background

MC-LAG (MultiChassis Link Aggregation Group, cross-device link aggregation group) is a network technology for connecting multiple switches into one logically single switch, thereby improving reliability, fault tolerance, and scalability of the network. In the MC-LAG scheme, the main switch and the standby switch are independent and respectively forward, and protocol synchronization is carried out through links so as to achieve the purpose of logic unification. When the link is normal and the MC-LAG two devices work normally, the current protocol can realize information synchronization and double-end forwarding.

Currently, when the MC-LAG scheme is used for traffic transmission, if the main switch restarts to disconnect the link, the information synchronization between the main switch and the standby switch must be out of step, so in the process of restarting the main switch, at the moment when the physical port of the main switch is closed, and at the moment when the negotiation of the LACP (Link Aggregation Control Protocol ) is completed after the main switch restarts, abnormal packet loss must occur in traffic transmission. According to the current problem carding and the verification of the actual environment, the main switch in the MC-LAG environment can be restarted, and the reason for packet loss and the time node are mainly two parts: when the main switch is restarted to be shut down, all physical ports on the main switch are required to be shut down, however, because the closing modes of a plurality of physical ports on the main switch are sequentially closed, network equipment in a flow transmission network may misunderstand that the physical ports with the back closing order are not closed currently in the closing process, and send message data to the physical ports, however, actually, the plurality of physical ports which are sequentially closed are not closed yet to the physical ports, at this time, the sent message data may not be closed yet to the physical ports, but the physical ports are closed first, and the condition leads to the loss of the message data which is originally transmitted. After the restart of the part 2 and the main exchanger is completed, the software system application is restarted, and each dock (open source application container engine) and the process responsible for port configuration are started in sequence to complete the configuration and initialization of the ports. When the ICCP (Inter-Chassis Communication Protocol ) module process starts, the main switch will re-negotiate the LACP protocol with the standby switch and establish a connection. Because the LACP negotiation stage is earlier, the traffic forwarding of the MC-LAG member interface of the main switch can be performed after the LACP negotiation is completed, however, the port configuration of the MC-LAG is likely to not be completed after the LACP negotiation is completed, and packet loss can occur if traffic forwarding is performed.

Aiming at the problems of high loss rate of message data and the like in the restarting process of the switch in the related technology, no effective solution is proposed yet

MC-LAG (MultiChassis Link Aggregation Group, cross-device Link aggregation group), a cross-device Link aggregation mechanism, is a technology based on a logical switch composed of multiple physical switches, and by aggregating multiple switches together to provide a function similar to a single multi-port logical connection, MC-LAG solves the problems of low utilization of redundant links and easy single point failure in a traditional STP (Spanning Tree Protocol ) network. The MC-LAG is regarded as a single logic processing unit by taking two physical switches as the single logic processing unit, can improve the reliability and fault tolerance of a network, improve the utilization rate of a link, unify a control plane and the like, and has advantages in various aspects, wherein in the aspects of improving the reliability and fault tolerance of the network, when one switch fails, the MC-LAG can automatically switch the flow to the other switch, thereby realizing quick recovery and reducing the network interruption time; in the aspect of improving the link utilization rate, the MC-LAG can simultaneously use a plurality of switches to provide service, single-point faults are avoided, so that the link utilization rate and the reliability of the whole network are improved, in the aspect of a unified control plane, the MC-LAG can regard two switches as a logic unit, and the two switches work cooperatively through the unified control plane, so that the management cost and the maintenance cost are reduced.

Packet loss: the term in network technology refers to the inability of data of one or more packets (packets) to reach a destination over the network.

In this embodiment, a method for restarting a switch is provided, and fig. 2 is a flowchart of a method for restarting a switch according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:

step S12, detecting a restarting operation triggered on a target switch, wherein a flow transmission network comprises a plurality of switch groups, the switches in the same switch group are logically embodied as a single switch in the flow transmission network, each switch group comprises a plurality of switches, and the plurality of switches comprise the target switch;

alternatively, in this embodiment, the traffic transmission network may be, but is not limited to, a network to which MC-LAG technology is applied, and fig. 3 is a schematic diagram of an MC-LAG traffic transmission network according to an embodiment of the present application, as shown in fig. 3, in the traffic transmission network to which MC-LAG is applied, where in a physical topology layer, the MC-LAG traffic transmission network includes two switch devices (device a and device B), where device a is a master switch, device B is a slave switch, and the master and slave devices are connected to one network device a downward, where information synchronization between device a and device B mainly depends on a link between the master and slave switches, including a pearlink link and a keep alive link, where when the device operates normally and the MC-LAG environment is successfully built, control information synchronization and traffic information transmission are performed through the link, and during this period mainly depends on a LACP protocol to perform state synchronization, and two lines connected to a downstream host can be regarded as an aggregate link through link aggregation, where two switches (device a and device B are equivalent to a logical device C) of the MC-LAG are seen as a logical topology device C. In this way, the requirements of providing redundancy backup, preventing disconnection, expanding bandwidth and the like are met.

In the MC-LAG traffic transmission network, a fault condition may occur in one of the two MC-LAG devices, and at this time, the faulty switch needs to be turned off and restarted. If the failed switch is a standby switch, the restarting effect is smaller, because the primary switch can maintain the original MAC table entry and continue forwarding; however, when the main switch is restarted, the MAC entries of the standby switch are obtained synchronously from the main switch, so that the restarting of the main switch may cause the change of the MAC entries in the standby switch, which directly causes the phenomenon that packet loss occurs in the forwarding of the traffic. Modern networks have fast transmission speed and high bandwidth, and once packet loss occurs, more serious network accidents occur.

Step S14, responding to the restarting operation, switching the operation state of the target switch from the current operation state to a target port state, wherein the target port state is used for indicating that network equipment in the traffic transmission network is not allowed to send message data to the target switch, and the target switch in the target port state is allowed to finish the restarting operation;

optionally, in this embodiment, the network device in the traffic transmission network identifies an operation state of the target switch, and if it is identified that the operation state of the target switch is a target port state, no message data is sent to the target switch;

Optionally, in this embodiment, the current operation state may be a non-target port state, and the network device in the traffic transmission network may send the message data to the target switch when identifying that the operation state of the target switch is the non-target port state

Step S16, stopping the target switch to realize the port function of the message transmission port of the single switch in the target switch group under the condition that the target switch is restarted and is to be added to the target switch group where the target switch is located;

optionally, in this embodiment, if the target switch implements a port function of a packet transmission port of the single switch in the target switch group, it indicates that the target switch forms a logically single switch with other switches in the target switch group.

Optionally, in this embodiment, after the restart of the main switch is completed in the above section 2, the software system application is restarted, and each dock (open source application container engine) and the process responsible for port configuration are sequentially started to complete the configuration and initialization of the ports. When the ICCP (Inter-Chassis Communication Protocol ) module process starts, the master switch will re-conduct LACP negotiation with the standby switch and establish a connection. In the related art, as the LACP negotiation stage is earlier, the flow forwarding of the MC-LAG member interface of the main switch is performed after the LACP negotiation is completed, however, the port configuration of the MC-LAG is likely to not be completed after the LACP negotiation is completed, and packet loss also occurs if the flow forwarding is performed at this time.

And S18, controlling the target switch to realize the operation of the message transmission port of the single switch in the target switch group according to the link configuration progress of the target switch added to the target switch group, wherein the link configuration progress is used for indicating the completed link configuration stage in the process of adding the target switch to the target switch group.

Optionally, in this embodiment, the foregoing mention that, in this application, by stopping the manner that the target switch implements the port function of the packet transmission port of the single switch in the target switch unit, LACP negotiation is avoided in advance, further, the operation of the target switch implementing the packet transmission port of the single switch in the target switch unit may be controlled according to the link configuration progress of the target switch joining to the target switch unit, and whether the target switch may implement the packet transmission port of the single switch in the target switch unit may be determined according to the link configuration progress of the current target switch joining to the target switch unit.

When the restarting operation triggered on the target switch is detected, the restarting operation of the target switch is not directly completed, but the operation state of the target switch is firstly switched from the current operation state to the target port state, wherein the target port state is used for indicating that network equipment in a traffic transmission network is not allowed to send message data to the target switch, the target switch in the target port state is allowed to complete the restarting operation, in this way, the condition that the sent message data possibly does not reach a physical port caused by a mode that a plurality of physical ports are successively closed on a main switch in the related art, but the physical port is closed first is avoided, so that the message data is prevented from being lost, and in addition, under the condition that the target switch is restarted and the target switch group where the target switch is to be newly added, the port function of the message transmission port of a single switch is realized in the target switch group by the target switch is stopped; according to the link configuration progress of the target switch added to the target switch unit, the target switch is controlled to realize the operation of the message transmission port of the single switch in the target switch unit, wherein the link configuration progress is used for indicating the completed link configuration stage in the process of adding the target switch to the target switch unit, the target switch can be prevented from realizing the port function of the message transmission port of the single switch in the target switch unit in advance, so that the link configuration progress of the target switch unit does not meet the requirement of transmitting message data, and the message data is directly transmitted through the message transmission port to cause the loss of the message data. By adopting the technical scheme, the problems of higher loss rate of the message data in the restarting process of the switch and the like in the related technology are solved, and the technical effect of reducing the loss rate of the message data in the restarting process of the switch is realized.

As an optional solution, the switching the operation state of the target switch from the current operation state to the target port state further includes:

s21, controlling the target switch to simultaneously close all data transmission ports on the target switch;

s22, under the condition that all the data transmission ports are closed, the running state of the target switch is determined to be in the target port state.

Optionally, in this embodiment, when the main switch is restarted and turned off, the physical ports on the main switch are all required to be turned off, however, because the turning-off modes of the physical ports on the main switch are sequentially turned off, in this turning-off process, the network device in the traffic transmission network may misunderstand that the physical ports with the back turning-off sequence are not turned off at present, and send the message data to the physical ports, however, actually, the physical ports that are turned off sequentially are not turned off yet, at this time, the sent message data may not be turned off yet, but the physical ports are turned off first, which is different from the case that the physical ports that are turned off sequentially in the related art are turned off, and this application controls the target switch to turn off all the data transmission ports on the target switch at the same time, and determines the running state that all the data transmission ports are turned off as the target port state.

As an alternative, the controlling the target switch to simultaneously close all data transmission ports on the target switch further includes:

s31, generating a first driving instruction, wherein the first driving instruction is used for indicating to simultaneously close all data transmission ports on the target switch;

s32, sending the first driving instruction to a first interactive interface deployed on a driving layer of the target switch, wherein the driving layer is used for responding to the first driving instruction transmitted on the first interactive interface to execute the operation of closing all data transmission ports on the target switch at the same time.

Optionally, in this embodiment, the closing of the physical port (corresponding to the data transmission port) of the target switch is mainly performed by the driving layer, and the closing of the physical port is performed by directly operating the register of the underlying hardware layer or directly operating the electrical layer through the driving layer. According to the method, the logic of the bottom layer is optimized firstly by the driving layer, and when the driving layer receives a reboot instruction (restarting instruction), all physical ports are closed simultaneously.

When the user issues a reboot instruction, the driver layer is informed that the driver layer is ready to execute a restarting operation at the moment, and the driver layer needs to close all physical ports at the same time. To ensure that the drive interaction is automatically completed. And the drive layer transmits an interactive interface, the upper layer program writes a 1 action to the interactive interface, and after receiving the drive instruction 1, the drive layer executes the operation of synchronously closing all physical ports. Meanwhile, in order to enable the process to be perfectly matched with the restarting process, the 1 action is written, the reboot file in the/usr/local/bin is directly loaded, the reboot file is an execution script of a reboot instruction, and corresponding process closing and exiting operations are executed by the execution script before shutdown, so that restarting is prepared.

As an alternative, the generating the first driving instruction includes: s41, searching a first identifier corresponding to the operation of simultaneously closing all data transmission ports on the target switch from the driving operation and identifiers with corresponding relations as the first driving instruction;

the sending the first driving instruction to the first interaction interface deployed on the driving layer of the target switch includes: and S42, sending a first identification to the first interactive interface, wherein the driving layer is used for executing the operation of closing all data transmission ports on the target switch simultaneously under the condition that the first interactive interface is detected to receive the first identification.

Alternatively, in this embodiment, the first identifier may be, but is not limited to be "1" above, and the first interaction interface may be, but is not limited to, an interaction interface that is transparent to the driving layer above.

s51, generating a second driving instruction, wherein the second driving instruction is used for indicating the target switch to execute the restarting operation;

And S52, sending the second driving instruction to a second interactive interface deployed on a driving layer of the target switch, wherein the driving layer is used for responding to the second driving instruction transmitted on the second interactive interface to execute the operation of closing all data transmission ports on the target switch at the same time.

Optionally, in this embodiment, S51 to S52 are different from S31 to S32 in that the first driving instruction is directly used to instruct to simultaneously close all data transmission ports on the target switch, while the second driving instruction is not directly used to instruct the target switch to simultaneously close all data transmission ports, but informs the driving layer that the current target switch is to perform the restart operation, and after the driving layer knows that the current target switch is to perform the restart operation, in order to cooperate with the target switch to perform the restart operation, the second driving instruction transmitted on the second interaction interface is responded to perform the operation of simultaneously closing all data transmission ports on the target switch.

As an alternative, the generating the second driving instruction further includes: s61, searching a second identifier corresponding to the restarting operation to be executed by the target switch from the driving operation and identifiers with the corresponding relation as the second driving instruction;

The sending the second driving instruction to the second interaction interface deployed on the driving layer of the target switch includes: and S62, sending a second identifier to the second interactive interface, wherein the driving layer is used for executing the operation of closing all data transmission ports on the target switch simultaneously under the condition that the second interactive interface is detected to receive the second identifier.

Alternatively, in the present embodiment, the implementation logic of S61 to S62 is similar to that of S41 to S42, and will not be described here.

s71, responding to the restarting operation, calling a restarting file, wherein the restarting file is used for recording a plurality of switch control actions of the target switch from the detection of the restarting operation to the execution of the restarting operation, the switch control actions are used for controlling the target switch to meet the condition of executing the restarting operation, and the switch control actions comprise target restarting actions for controlling the target switch to simultaneously close all data transmission ports on the target switch;

S72, running the restart file.

Optionally, in this embodiment, the restart file corresponds to the reboot file, where the reboot file records multiple switch control actions between the detection of the restart operation and the execution of the restart operation of the target switch, executes corresponding process closing and exiting operations, prepares for the restart, uses a first switch control action in the multiple switch control actions as the detection of the restart operation, and uses a last switch control action as the execution of the restart operation, where before the last switch control action, the method further includes a target restart action, where a target restart action acts to control the target switch to simultaneously close all data transmission ports on the target switch.

As an alternative, the switching the operation state of the target switch from the current operation state to the target port state in response to the restart operation further includes:

s81, responding to the restarting operation, detecting the switch type of each switch in the switch group, wherein the switch type comprises: a primary type and a backup type;

s82, when the switch type of the target switch is the main type, switching the running state of the target switch from the current running state to a target port state;

S83, executing the restarting operation directly on the target switch under the condition that the switch type of the target switch is the standby type.

Optionally, in this embodiment, in the MC-LAG traffic transmission network, a fault condition may be encountered in one of the two MC-LAG devices, and at this time, the failed switch needs to be turned off and restarted. If the failed switch is a standby switch, the restarting effect is smaller, because the primary switch can maintain the original MAC table entry and continue forwarding; however, when the main switch is restarted, the MAC entries of the standby switch are obtained synchronously from the main switch, so that the restarting of the main switch may cause the change of the MAC entries in the standby switch, which directly causes the phenomenon that packet loss occurs in the forwarding of the traffic. Modern networks have fast transmission speed and high bandwidth, and once packet loss occurs, more serious network accidents occur. Therefore, in response to the restart operation, in the process of switching the operation state of the target switch from the current operation state to the target port state, the switch type to which each switch in the switch group belongs is detected first, and in the case where the switch type to which the target switch belongs is the active type (i.e., the target switch is the primary switch), the operation state of the target switch is switched from the current operation state to the target port state, and in the case where the switch type to which the target switch belongs is the standby type (i.e., the target switch is the standby switch), since the restart effect is small when the above-mentioned failed switch is the standby switch, the restart operation can be performed directly on the target switch.

As an optional solution, the controlling, according to the link configuration progress of the target switch joining to the target switch unit, the operation of the target switch to implement the message transmission port of the single switch in the target switch unit further includes:

s91, detecting the link configuration progress of the target exchanger added to the target exchanger group;

s92, recovering the target switch to realize the port function of the message transmission port of the single switch in the target switch group under the condition that the link configuration progress is used for indicating that the target switch completes the configuration stage of the port function in the process of joining the target switch to the target switch group.

Optionally, in this embodiment, after the restart of the main switch is completed in the above section 2, the software system applications are restarted, and each dock (open source application container engine) and the process responsible for port configuration are sequentially started to complete the configuration and initialization of the ports. When the ICCP (Inter-Chassis Communication Protocol ) module process starts, the main switch will re-negotiate the LACP protocol with the standby switch and establish a connection. Because the LACP negotiation stage is earlier, the traffic forwarding of the MC-LAG member interface of the main switch can be performed after the LACP negotiation is completed, however, the port configuration of the MC-LAG is likely to not be completed after the LACP negotiation is completed, and packet loss can occur if traffic forwarding is performed. In the method, LACP negotiation is avoided in advance by stopping the target switch to realize the port function of the message transmission port of the single switch in the target switch unit, so that the condition that the link configuration progress of the target switch unit does not reach the requirement of transmitting message data yet, the message data is transmitted directly through the message transmission port, and the message data is lost is caused.

In order to ensure that after the main switch in the MC-LAG is restarted, renegotiation is carried out with the standby switch, and packet loss caused by out-of-step occurs, the following scheme is adopted for avoiding:

1. after restarting the main switch of the MC-LAG, adding a function code to the teammrd process, fig. 4 is a schematic diagram of an MC-LAG member interface control mechanism according to an embodiment of the present application, as shown in fig. 4, when a team link of the main switch is established, determining a link attribute of the team link by using an MC-LAG member interface and an aggregate link with a corresponding relationship recorded in a configDB (configuration database), and if the link attribute indicates that a port of the team link is an MC-LAG member interface, directly turning off the MC-LAG member interface shutdown, and stopping a port function of a port of the team link. the main purpose of the teammrd process is to perform creation and initialization of a team link group according to configuration information in a user configuration and configDB (configuration database), including creation and initialization of portchannels corresponding to MC-LAG member interfaces, where the MC-LAG member interfaces correspond to link aggregation groups portchannels, each PortChannel corresponds to a team link group, and creation of a team link is completed in the teammgr process.

2. The main purpose of dropping the MC-LAG member interface section is to avoid LACP negotiation in advance by a team link corresponding to the MC-LAG member interface section, and packet loss caused by the situation in the part 2 is caused, but the time of dropping the MC-LAG member interface section cannot last too long, otherwise the normal function of the target switch is affected. Setting the longest time for the MC-LAG member interface to fall can reach 300s, starting timing from the fall of the MC-LAG member interface to finish the fall of the section after the MC-LAG is in a creating finish state, if the MC-LAG is not in the creating finish, but the time for the fall of the MC-LAG member interface to fall can reach 300s, and teammrd can judge overtime, namely finishing all processes, finishing the fall of the section to the MC-LAG member interface, and turning on all MC-LAG member interface states.

3. The MC-LAG member interfaces are cut off, which means that the MC-LAG member interfaces do not carry out LACP protocol negotiation or do not succeed, so that negotiation is unsuccessful in MC-LAG control logic, at this time, all MC-LAG member interfaces of the main switch do not forward traffic (message data), and at this time, the traffic is still forwarded by the standby switch.

4. The MC-LAG member interface of the main switch is cut off, traffic forwarding is not performed, but other links of the main switch are still started normally, and particularly links where the peerlink link and the keepalive link are located still work normally. After the ICCP module of the main switch is normally started, the main switch and the standby switch normally negotiate through a peerlink link, prepare to build an MC-LAG environment, wait for the completion of the MC-LAG environment building, and write a target STATE identifier corresponding to the MC-LAG building STATE being the building completion STATE into a STATE_DB (STATE database) in host equipment. Meanwhile, a newly added function code in the teammrd process carries out overtime judgment and MC-LAG state identification judgment, if the MC-LAG state identification is a target state identification or the period of time that the MC-LAG member interface is dropped by the chut is more than 300s, all logic mechanisms of the function are exited, and the states of all MC-LAG member interfaces are up.

5. Through the mode, the purpose of avoiding packet loss can be achieved. However, a special case needs to be considered, and if someone modifies part of the configuration of the MC-LAG member interface, such as adding or deleting part of the MC-LAG member interface, in the first 300s after the restart of the main switch, the control logic needs to be ensured to be met for the newly added and changed MC-LAG member interface. In order to meet the requirements, a task process is newly added in the teammrd process and is mainly responsible for monitoring the result of user operation, the task process is mainly responsible for monitoring the list item of the MC-LAG member interface, if the newly added MC-LAG member interface exists in the waiting 300S, the state of the MC-LAG member interface is needed to be shed, the MC-LAG member interface is waited for being identified as a target state identification, or the MCLAC member interface is restarted after the link closing time reaches the target time (300S); otherwise, if someone removes the original MC-LAG member interface within 300s, because the teammrd process has already removed the MC-LAG member interface section from the beginning, after removal, the section of processing logic is not needed to be executed any more, and the MC-LAG member interface is directly up. The task mechanism is only validated and executed within 300 seconds of waiting, and after timeout, the logic code automatically ends and is not executed any more.
