Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a machine-readable storage medium for master/slave switching management.

Background

RBM (Remote Backup Management) provides a technique for backing up key configuration information and service table entries between devices. The method can realize the dual-computer hot standby function by matching with the VRRP technology, so as to ensure that the standby equipment can smoothly take over the main equipment to work when the main equipment in the network fails, and ensure the uninterrupted transmission of user service data.

VRRP (Virtual Router Redundancy Protocol) adds a group of gateway routers to a backup group to form a Virtual Router, where a Virtual address can be used as a gateway address, and the VRRP can still provide a high-reliability link when one of the routers fails to ensure that services in the network are normal. However, when a plurality of backup groups exist in the VRRP networking, when the states of the VRRP upstream or downstream faults are not synchronous, the master devices in the backup groups are inconsistent, and the problem of inconsistent states of the plurality of backup groups of the VRRP can be solved by controlling the VRRP through the RBM. When VRRP backup groups are created, all VRRP backup groups on equipment are associated with the RBM, the RBM monitors and manages the states of the VRRP backup groups through the control channel, and if the state of one of the VRRP backup groups changes, the RBM can control all the VRRP backup groups to uniformly switch the states, so that the consistency of the states of all the VRRP backup groups is ensured. The RBM and the VRRP are used in combination, so that the standby equipment can smoothly take over the main equipment to work when the main equipment in the network fails, the uninterrupted transmission of user service data is ensured, and the hot standby of the two machines is realized.

With the development of the technology, the user demand and the network operation quality are continuously improved, the VRRP + LB network is generated, and when two VRRP backup groups exist in a downlink, the technical problem that the main-standby switching process is unreasonable exists in the link switching at the moment.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure.

As in fig. 4, FW1 is configured as primary by default and FW2 is configured as backup by default.

When RBM configuration is not switched back by default, FW2 is standby equipment, one link (B2 or C2) Down is in a FW2 interface downlink, all downlink ports (A1, B1 and C1) in a FW1 interface uplink and downlink are Down, the link is not switched between FW2 and backup up (all links of the standby equipment FW2 are required to be switched to be main normally), but the uplink and the downlink of the FW2 equipment have available links, and the problem of unreasonable main-standby switching exists at this moment.

If one downlink of FW2 recovers UP, then FW2 is switched to be the main; then the A1 and B1 (or C1) links of the FW1 recover UP, and the FW2 is also a master; at this time, all links of the FW2 fail Down (a2, B2 and C2), and at this time, the FW1 is still standby, the FW1 is switched to be the main link until all links of the FW1 recover UP, and the main-standby switching is unreasonable.

When the RBM configuration defaults to back-off, an FW1 uplink and downlink link (A1, B1 and C1) fails, FW2 is switched to standby, then one link (B2 or C2) of the FW2 fails Down, FW2 is switched to standby again, and the switching is meaningless because FW1 is unavailable.

In summary, the switching mechanism of the RBM should be that the main device link UP is detected to perform switching, but not that the other side down performs switching; whether the configuration is switched back or not should be compared with the main and standby device links, and the switching back or not can be selected only by detecting one side.

In view of this, the present disclosure provides a method and an apparatus for master/slave switching management, an electronic device, and a machine-readable storage medium, so as to solve the problem that the master/slave switching process is unreasonable.

The specific technical scheme is as follows.

In an embodiment, the present disclosure provides a method for master/slave switching management, which is applied to a network management device, and the method includes: respectively acquiring current link states of a main network device and a standby network device; respectively adjusting the priority values of the main network equipment and the standby network equipment according to the current link states of the main network equipment and the standby network equipment; determining a new main network device according to the priority values of the main network device and the standby network device; the primary network device and the standby network device are configured with an initial priority value, the initial priority value of the primary network device being higher than the initial priority value of the standby network device.

Specifically, as shown in fig. 1, the method comprises the following steps:

step S11, respectively obtaining the current link states of the main network device and the standby network device;

step S12, respectively adjusting the priority values of the main network device and the standby network device according to the current link states of the main network device and the standby network device;

step S13, determining a new master network device according to the priority values of the master network device and the standby network device.

The primary network device and the standby network device are configured with an initial priority value, the initial priority value of the primary network device being higher than the initial priority value of the standby network device.

The states of all links of the main and standby network devices are analyzed respectively, so that a priority value is evaluated for the main and standby network devices respectively, whether main and standby switching is needed or not is judged according to the priority value, and therefore the situation that when partial faults exist in all the links, the devices with relatively worse network states are used as the main network devices is avoided.

In one embodiment, the adjusting the priority values of the master network device and the standby network device according to the current link states of the master network device and the standby network device respectively includes: and respectively configuring different adjustment values according to the importance of different links, and adjusting the priority values of the associated main and standby network devices according to the uplink and downlink states of the links and the associated adjustment values.

In one embodiment, the determining a new master network device according to the priority values of the master network device and the standby network device includes: and if the priority value of the current standby network equipment is higher than that of the current main network equipment, configuring the current standby network equipment as new main network equipment, and performing main-standby switching according to a configuration result.

In one embodiment, adjusting the priority values of the master network device and the standby network device according to the current link states of the master network device and the standby network device respectively includes: and if the link states of the uplink group or the downlink group are all offline, setting the priority value of the associated network equipment to be the lowest.

In one embodiment, the default priority values 65535 and 65534 are respectively configured for the active and standby network devices, and the priority value range is 0-65535, wherein 0 represents no preemption of the primary device, and a higher priority value indicates a higher priority to elect the primary device.

FW1 interface or link failure Down, RBM controls VRRP state switching process as follows:

the FW1 interface Down senses the status Down of FW1 link, reduces the priority value of FW1, and compares the priority values of FW1 and FW2 with each other, if the priority value of FW2 is higher, the status of FW2 is controlled to be switched to the Master device, and the status of FW1 is controlled to be switched to the Backup device.

The adjustment of the priority value can be set by adding a judgment mechanism in the switching process, wherein FW1 is set as a master management device, FW2 is set as a slave management device, the initial FW1 has a priority value of 65535, the FW2 has a priority value of 65534, the link state can be monitored in combination with Track or BFD, and when FW1 has an interface failure Down, the RBM receives a message management VRRP backup group and reduces the priority value of FW 1. Adding a loop judgment process, monitoring whether all links are Down or unidirectional (all uplink links or all downlink links) are full Down, namely the FW1 flow is not communicated, and if so, configuring the priority value of corresponding equipment to be 1; otherwise, the priority value is decreased by 10 every Down link, that is, when there are n interface failures, the priority value is 65535-10 × n.

When FW1 link full Down or unidirectional full Down, the priority value is 1, if FW2 individual link fails Down, but there is no link full Down or unidirectional full Down, the priority value of FW2 is still higher than FW1, at this time, no switching is performed, and the problem of unreasonable switching can be effectively solved.

In one embodiment, the adjusting the priority values of the master network device and the standby network device according to the current link states of the master network device and the standby network device respectively includes: and respectively configuring different adjustment values according to the importance of different links, and adjusting the priority values of the associated main and standby network devices according to the uplink and downlink states of the links and the associated adjustment values.

In one embodiment, the determining a new master network device according to the priority values of the master network device and the standby network device includes: and if the priority value of the current standby network equipment is higher than that of the current main network equipment, configuring the current standby network equipment as new main network equipment, and performing main-standby switching according to a configuration result.
