Description

VRRP (virtual router redundancy protocol) linkage switching method and device and electronic equipment

Technical Field

The invention relates to the technical field of communication, in particular to a VRRP linkage switching method and device and electronic equipment.

Background

Virtual Router Redundancy Protocol (VRRP) is a routing Protocol proposed by IETF for solving the single point failure phenomenon of a static gateway configured in a local area network, and can dynamically allocate the responsibility of a Virtual Router to one of VRRP routers on the local area network. As shown in fig. 1, in a typical VRRP access networking, a VRRP group is established between a VRRP1 device and a VRRP2 device, and a user accesses an outbound network through the VRRP group via a switch, generally, an uplink interface (an interface between the VRRP group and LSW 2) is deployed on the VRRP group in such a networking, and it is ensured that a primary-standby switch of the VRRP group is triggered when the uplink interface of the VRRP group fails, so that a user gateway is switched to a standby device, and further, a service can be normally switched to the standby device for operation.

However, some scene switches can be problematic: the downstream interface of the VRRP group (the interface to which the VRRP group is connected to LSW 1) enables the VRRP group, typically more than one of the VRRP groups. If there are 3 services accessing to the VRRP group, the access bandwidth of each service is 2G, and there are 3 corresponding VRRP groups, at this time, the suitable outlet of the VRRP group is an equivalent outlet formed by 2 interfaces with 3G bandwidth, so that the uplink and downlink bandwidths are equal. Taking uplink transmission as an example, an uplink outlet corresponds to three VRRP groups, and each VRRP group is associated with the same interface field and state field to perform linkage switching, so that when one or more uplink interfaces fail, either the three VRRP groups are switched or the three VRRP groups are not switched, and a corresponding result is that if the three VRRP groups are switched, all services are affected; if none of the three VRRP groups switch, all traffic may be lost.

In summary, there is no solution to the problem that when multiple VRRP groups are associated with the same uplink interface, if a certain or some of the uplink interfaces have a reduced bandwidth due to a failure, the active/standby VRRP groups cannot be effectively switched.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, in a VRRP access networking, when a user initiates network access to the outside, if an uplink interface fails, a VRRP group needs to be triggered to perform active/standby switching, so that a user gateway service is switched to a standby device, and the service can run normally. However, there are problems with the active-standby switching in some scenarios: generally, a VRRP access network generally has more than one VRRP group. If three services are simultaneously accessed to the VRRP access network, assuming that the access bandwidth of each service is two G, three corresponding VRRP groups are provided, at this time, the uplink interface adapted to the VRRP group is an equivalent outlet formed by two interfaces with the bandwidth of 3G, that is, the uplink interface corresponds to the three VRRP groups, and each VRRP group is associated with the same state of the uplink interface to perform linkage switching. However, in the current implementation process, either three VRRP groups are switched, and all services are affected at this time; or three VRRP groups are not switched, and all traffic may be lost.

Based on this, the VRRP linkage switching method, the VRRP linkage switching device and the electronic device provided by the embodiments of the present invention can conveniently and effectively implement active/standby switching of the VRRP access network when the bandwidth of the uplink interface is reduced.

To facilitate understanding of the embodiment, a detailed description will be given to a VRRP linkage switching method disclosed in the embodiment of the present invention.

The embodiment of the invention provides a VRRP linkage switching method.

In accordance with an embodiment of the present invention, a more detailed embodiment of a VRRP linkage switching method is provided, it should be noted that the steps illustrated in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.

Referring to fig. 2, the VRRP linkage switching method provided in this embodiment is applied to a VRRP access network including a plurality of virtual router redundancy protocol VRRP groups, and specifically includes the following steps:

step S101: and if the uplink interface of the VRRP access networking fails, acquiring the sum of the bandwidths of the non-failure uplink interfaces.

Step S102: and judging a plurality of services which can be simultaneously satisfied by the sum of the bandwidths, wherein the priorities of the services are higher than those of the rest services.

Step S103: and performing active-standby switching on VRRP groups corresponding to the rest services.

In summary, the VRRP linkage switching method provided in this embodiment is applied to a VRRP access network including multiple VRRP groups, and includes: firstly, if an uplink interface of a VRRP access networking fails, acquiring the sum of bandwidths of non-failed uplink interfaces, measuring the capacity of the VRRP access networking for transmitting services by the sum of the bandwidths, then, judging a plurality of services which can be simultaneously met by the sum of the bandwidths, wherein the priorities of the services are higher than those of the rest services, namely, the services are divided into the services and the rest services according to the priorities, then, performing master-slave switching on the VRRP groups corresponding to the rest services (i.e. the services with lower priorities), and through the processing process, when the uplink interface of the VRRP access networking fails, only performing master-slave switching on the VRRP groups corresponding to the services with lower priorities, so that not only the services with higher priorities are ensured to be continuously processed on the master device, but also the services with lower priorities are ensured to be not influenced on the master-slave device after the master-slave switching, the processing procedure improves the phenomenon that all VRRP groups are switched between the main and standby modes or are not switched in the prior art, realizes effective switching of the VRRP groups, and is convenient and quick.

Example 2

The embodiment of the invention provides a VRRP linkage switching method.

Referring to fig. 2 and fig. 3, the VRRP linkage switching method provided in this embodiment is applied to a VRRP access network including a plurality of virtual router redundancy protocol VRRP groups, and specifically includes the following steps:

It should be noted that the non-failure uplink interface and the failure uplink interface are both uplink interfaces connected to the VRRP access networking, and since the VRRP access networking includes a plurality of VRRP groups, the number of corresponding uplink interfaces is plural. When one uplink interface fails, acquiring the sum of the bandwidths of all the non-failure uplink interfaces except the uplink interface; and when two uplink interfaces have faults, acquiring the sum of the bandwidths of all the non-fault uplink interfaces except the two uplink interfaces, and so on.

Because the VRRP access networking comprises a plurality of VRRP groups, the corresponding accessed services can be various, and the priority of the various services is preset from high to low. When an uplink interface fails, comparing the sum of the bandwidths with the access bandwidth occupied by the services with the priorities from high to low, judging the services which can be simultaneously met by the sum of the bandwidths, and effectively screening a plurality of services with higher priorities and the rest services with lower priorities through the operation.

In the implementation process, the step S102 determines, according to the order from high to low of the service priority, a service that the sum of bandwidths can be simultaneously satisfied, and specifically includes:

step S1021: and a judging step, namely judging a plurality of services which can be simultaneously satisfied by the sum of the bandwidths, wherein the priorities of the services are higher than those of the rest services.

Where n has an initial value of 1, i.e. starting from the first 1 service with the highest priority. If not, go to step S1022; if yes, proceed to step S1023.

Namely, the state observation table is updated by the judgment. And if the uplink interface fails, changing the value of the interface field corresponding to the failed uplink interface from the normal value to the failure value.

Supposing that a failure occurs on the uplink interface D, at this time, the state of the state observation table needs to be switched, that is, the interface field of the uplink interface D is changed from UP to DOMN, at this time, the interface with the state UP in the state observation table has only E and F, and the sum of the bandwidths of the interfaces is 4G. Judging whether the sum of the bandwidths can simultaneously satisfy the first n services with the highest priority, wherein the sum of the bandwidths (namely 4G) needs to be compared with the sum of the access bandwidths of the service A, B, C, and the comparison sequence from the high-priority service to the next is as follows:

e + F ═ 4G > C ═ 1G, so the bandwidth of the highest priority C service can be effectively guaranteed, and continue to compare;

e + F ═ 4G > B + C ═ 3G, so the sum of the highest priority service C and the second best priority service B can also be effectively guaranteed, and continue to compare;

and E + F is 4G < A + B + C is 6G, and the bandwidth is insufficient when the three services exist simultaneously. The reason is that the service a with lower priority is added at the time of comparison.

Step S1022: and judging that the services with the priority ranked at the nth bit and the lower priority are all the residual services.

That is, corresponding to the above-mentioned operation procedure that E + F is 4G < a + B + C is 6G, and in this case, when three services exist simultaneously, the bandwidth is insufficient.

In this case, the service a with the 3 rd priority is determined as the remaining service, and it is determined that the service with the lowest priority needs to be subjected to VRRP handover.

Step S1023: and adding 1 to the value of n, and returning to the judging step.

And returning to the step S1021, and continuously judging whether the sum of the bandwidths can simultaneously meet the first n services with the highest priority.

That is, the bandwidth of the C service with the highest priority can be effectively guaranteed since the E + F is equal to 4G > C is equal to 1G, and the comparison is continued; and E + F ═ 4G > B + C ═ 3G, so the sum of the highest priority service C and the second priority service B can be effectively guaranteed, and the operation step of the next comparison is continued.

In step S103, the main/standby switching is performed on the VRRP groups corresponding to the remaining services, which specifically includes:

continuing with the above example, based on the value of the status field, the value of the status field is 1, and the VRRP group of the remaining service is determined to be the VRRP group corresponding to service a.

And then, performing active-standby switching on the VRRP groups corresponding to the rest services, namely performing active-standby switching on the VRRP group corresponding to the service A.

Continuing with the above example, similarly, when the E-exit fails again, step S1021 is executed again: a comparison is made according to the description of the method above,

f ═ 2G > C ═ 1G, so the bandwidth of the highest priority C service can be effectively guaranteed, and continue to compare;

f is 2G and B + C is 3G, and at this time, the sum of the highest priority service C and the second best priority service B cannot be effectively guaranteed, and the bandwidth is insufficient. The reason is that the sub-optimal priority service B is added to the comparison.

Step S1022 is executed again: in this case, service a and service B are the remaining services, and the interface fields of both service a and service B are changed to DOWN. And updating the initial value 100 of the state field of the service B in the state observation table to the configuration 2 of the VRRP group corresponding to the service B.

And informing the VRRP group to switch after the state of the state observation table is changed, wherein because Status is 2, the service A is switched and the switching-back condition is not triggered to keep the current state, the service B is in accordance with the switching condition to trigger VRRP switching, and the corresponding VRRP group is not switched if the service C is not in accordance with the switching condition.

Similarly, when the F outlet fails again, step S1021 is executed again: a comparison is made according to the description of the method above,

since 0G < C is 1G, the bandwidth of the highest priority C service cannot be effectively guaranteed, and the bandwidth is insufficient.

Step S1022 is executed again: in this case, service a, service B, and service C are the remaining services, and the interface fields of service a, service B, and service C are all changed to DOWN. And updating the initial value 100 of the state field of the service B in the state observation table to be the configuration 3 of the VRRP group corresponding to the service C.

After the service that can be satisfied by the sum of the bandwidths at the same time is determined in step S102, the remaining service, i.e., the remaining service, that is, the service remaining from the sum of the bandwidths is also determined at the same time. Under the condition, the VRRP groups corresponding to the rest services are selected to carry out the main-standby switching, so that the main-standby switching of the specific VRRP groups is pertinently realized, the rest services are switched to the standby equipment, and the normal operation of the services on the standby equipment is further ensured.

In order to monitor the state of the uplink interface in real time, the VRRP linkage switching method further includes: and a state observation table is preset, and in order to facilitate the state monitoring of each service, a virtual observation group is established for each service on the equipment. For example, in a VRRP access networking, three services A, B, C exist in a downlink access, corresponding bandwidths are 3G, 2G, and 1G, respectively, and priorities are C, B, A from high to low. The upstream interfaces have equivalent outlets D, E, F, each with a bandwidth of 2G, and the upstream interface D, E, F is added to the virtual observation group, while the downstream traffic A, B, C is added to the virtual observation group according to its respective traffic priority.

And, the state observation table includes a state field and a plurality of interface fields, and the value of the interface field is related to the state of the uplink interface. Continuing the description of the above example, since all of the D, E, F are uplink interfaces, all of the values of the interface field D, E, F are UP, and in the implementation process, the number of the interface field may be expanded according to the number of the added uplink interfaces; the status field is specifically determined according to the bandwidth of each uplink interface and the sum of the interface bandwidths of the VRRP group linked with the virtual observation group.

The values of the status fields are related to the values of the interface fields, and the values of the status fields represent the VRRP groups corresponding to the remaining services. Specifically, the following relationship is established between the value of the status field and the value of each interface field, and the configuration of the VRRP group corresponding to the downlink service A, B, C is as follows:

VRRP A track watch1 status 1

VRRP B track watch1 status 2

VRRP C track watch1 status 3

the value of the status field represents the VRRP group corresponding to the remaining service, and it is shown from the above configuration that when only one of the upstream interfaces D, E, F has a failure, the service a needs to be switched between the master and the slave; when only one uplink interface fails, the service A needs to be switched between the main service and the standby service; when two uplink interfaces fail, the services A and B need to be switched between the main and standby; the service A needs to be switched between the main service and the standby service; when there are three uplink interface failures, the services A, B and C need to be switched between master and slave, so as to ensure that the sum of the bandwidths of the uplink interfaces on the master device is greater than the sum of the bandwidths of the services that need to be processed, and the services that cannot be satisfied on the master device are handed over to the slave device for processing.

In the implementation process, the state field and the plurality of interface fields of each uplink interface are given initial values to indicate the current state of each uplink interface. In the initial state, the state observation table of the upstream interface D, E, F is set as follows:

TABLE 1

Index

F type

Status

UP

100

Here, it should be noted that, before the master-slave switching of the VRRP group, a default value is set for the value of the state field, where the default value is greater than the value of the state field corresponding to the highest priority service of the service, as shown in table 1, the size of the default value may be flexibly customized according to needs, in this embodiment, as shown in table 1 above, the state value, i.e., the status value, is 100, and is greater than the status values 1, 2, and 3 of the VRRP group corresponding to the service A, B, C, so that none of the three services A, B, C triggers the master-slave switching of the VRRP group.

Corresponding to the case where the service a is the remaining service in step 1022. And updating the initial value 100 of the state field of the service A in the state observation table to be the configuration 1 of the VRRP group corresponding to the service A.

The state observation table at this time is as follows:

Here, it should be noted that, before the VRRP group performs the active/standby switching, a default value is set for the value of the status field, and when the service a is the remaining service, the value of the status field related to the value of each current interface field is obtained, as shown in table 2 above, the value of the status field of the VRRP group corresponding to the service a is 1, so the VRRP group corresponding to the service a performs the active/standby switching.

Corresponding to the service a and the service B being the remaining services in the above step 1022, the interface fields of both the service a and the service B are changed to DOWN. And updating the initial value 100 of the state field of the service B in the state observation table to the configuration 2 of the VRRP group corresponding to the service B.

The state observation table at this time is as follows:

Here, it should be noted that, before the primary/standby switching of the VRRP group is performed, a default value is set for the value of the status field, and in the case that the services a and B are the remaining services, the value of the status field related to the value of each current interface field is obtained, as shown in table 3 above, the value of the status field of the VRRP group corresponding to the services a and B is 2, so that the VRRP groups corresponding to the services a and B are both subjected to the primary/standby switching.

And informing the VRRP group to switch after the state of the state observation table is changed, wherein because Status is 2, the service A is switched and the switching-back condition is not triggered to keep the current state, the service B is in accordance with the switching condition to trigger VRRP switching, and the service C is not switched if the service C is not in accordance with the switching condition.

Corresponding to the case where the service C is the remaining service in step 1022. And updating the initial value 100 of the state field of the service C in the state observation table to be the configuration 3 of the VRRP group corresponding to the service C.

The state observation table at this time is as follows:

Here, it should be noted that, before the primary/standby switching of the VRRP group is performed, a default value is set for the value of the status field, and in the case that the services A, B and C are the remaining services, the value of the status field related to the value of each current interface field is obtained, as shown in table 4 above, the value of the status field of the VRRP group corresponding to the service A, B and C is 3, so that the VRRP groups corresponding to the services A, B and C both perform the primary/standby switching.

And after the state of the state observation table is changed, informing the VRRP group to switch, wherein because Status is 3, the services A and B are switched, and the switching-back condition is not triggered to keep the current situation, and the service C meets the switching condition to trigger the switching of the VRRP group.

In addition, the VRRP linkage switching method further includes: and if the uplink interface fails, changing the value of the interface field corresponding to the failed uplink interface from the normal value to the failure value. For example, when the upstream interface D fails, the value of the interface field is changed from the original UP to DOWN; when the uplink interface E also fails, the value of the interface field is also changed from the original UP to DOWN, etc. Through the change of the state, related workers can know the running condition of the uplink interface in time, and the method is convenient and fast.

In addition, the VRRP linkage switching method further includes: after the fault of the uplink interface is repaired, the process that the VRRP group performs the main/standby switching back is the reverse process of the main/standby switching, namely the service switching back is performed according to the value of the state field.

In summary, the VRRP linkage switching method provided in this embodiment is applied to a VRRP access network including a plurality of VRRP groups, and includes: firstly, if the uplink interface of the VRRP access networking is failed, acquiring the bandwidth sum of the non-failed uplink interface, secondly, judging a plurality of services which can be simultaneously met by the bandwidth sum, wherein the priorities of the services are all higher than those of the rest services, then, carrying out active/standby switching on the VRRP group corresponding to the rest services, and in order to facilitate the effective switching of the VRRP group, also presetting a state observation table, establishing a state field and a plurality of interface fields in the state observation table, updating the state field and the interface fields in real time after the judgment, determining the VRRP group which needs to be subjected to the active/standby switching according to the value of the state field, and by the processing method, the effective active/standby switching of the VRRP group can be carried out in the VRRP access networking under the condition that the bandwidth of the uplink interface is reduced, namely, by the setting of the state field and the interface field in the state observation table, the method simply, conveniently and efficiently records the measurement condition of the VRRP access networking transmission service capability and the judgment condition of the service priority level, so that the VRRP group corresponding to the service with the low priority level is switched between the master and the slave, the method is convenient and rapid, and the real-time performance of the service is ensured on the premise of not influencing the service.
