Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a method for establishing a service cutover plan.
Referring to fig. 1, there is shown a flow chart of a first embodiment of the method for establishing a service cutover plan according to the present invention.
In a first embodiment, the method for establishing a service cutover plan includes:
in step S10, a cutover group is created in the cutover plan.
Step S20, dividing the service parameters into a plurality of first parameter groups based on the dependency relationship between the service parameters in the first service to be cutover.
Step S30, adding the first parameter group to the created cutover group.
Before network cutover, a complete cutover plan needs to be created, and the cutover plan includes a complete service parameter of a first service to be cutover and a service parameter of a second service created in advance. The first service refers to a service already existing in the existing network before the execution of the cutover action, and the second service refers to a service which is pre-established in the network management and is ready to replace the first service in the cutover process.
In the present embodiment, a cutover plan for establishing a PTN network is taken as an example for explanation, and in other embodiments, other network cutover may be performed. The PTN network includes various emulated services, such as emulated ethernet services, emulated TDM (time-division multiplexing) services, etc., and generally, there is a complex dependency relationship between service parameters in the services to be cut, and these parameters cannot be separated during the cutting. For example, the service parameters such as ethernet service in the emulated ethernet service, working pseudo wire on which the ethernet service depends, OAM of the working pseudo wire, protection pseudo wire, OAM of the protection pseudo wire, and pseudo wire protection group. In this embodiment, a cutover parameter group is used as a minimum unit for resource sharing, and when a cutover plan is established, service parameters are divided into a plurality of first parameter groups based on a dependency relationship among services in first services to be cutover, for example, each unprotected tunnel to be cutover and its OAM configuration (if any) form one cutover parameter group; each pair of working, protection tunnel and its OAM configuration (if any), protection group configuration (if any) together form a cutover parameter set; each emulation service to be cutover, along with its working pseudowire/working multi-segment pseudowire, protection pseudowire/protection multi-segment pseudowire (if any), and pseudowire OAM configuration (if any), pseudowire protection group configuration (if any), collectively form a cutover parameter set.
The method comprises the steps of establishing a relation table among a plurality of service parameters of the service to be cut, judging the dependence relation, and judging the dependence relation according to the relation table when grouping.
Step S40, dividing the service parameters into a plurality of second parameter groups based on the pre-created dependencies between the service parameters in the second service.
Step S50, adding the second parameter set to the created cutover group.
The parameter set is an atomic unit that cannot be subdivided in the segmentation process, and is divided into a first parameter set and a second parameter set. The first parameter group refers to the parameter group of the service to be cut existing in the network before the cutting action is executed, and the second parameter group refers to the parameter group which is pre-established in the network management and is ready to replace the first parameter group in the cutting process. And in one segmentation group, after confirming that the creation of the first parameter group is completed, forming the service parameters with the dependency relationship in the pre-created second service into a second parameter group, and adding the created first parameter group and the created second parameter group into the same segmentation group.
In the present embodiment, the first parameter group and the second parameter group may be paired or not paired. If the parameters are paired, the resources released by the first parameter set in the cutting-over pair can only be pre-supported by the paired second parameter set, and other second parameter sets can not be pre-supported. And a cutting pair forms a minimum cutting and replacing action, in the process, the service connection relation represented by the first parameter group is removed from the equipment and replaced by the service connection relation represented by the second parameter group, and if an error occurs in the cutting process, the cutting pair automatically rolls back to a state before the cutting operation is started.
If the cutover parameter group is directly added into the cutover group under the condition of no pair, at this time, the resource is shared in the whole range of the cutover group, that is, the resource released by any first parameter group in the group can be pre-supported by any second parameter group in the cutover group.
Further, after completing the creation of a cutover group, the user may determine whether to continue to create the cutover group in the cutover plan according to the requirement, and if so, continue to perform steps S10 to S50 until the cutover plan is completed.
It should be noted that a plurality of cutover groups may together form a cutover plan. The various cutting groups in the cutting plan have no operational interdependence relationship, and the cutting plans are formed by the cutting groups and are more used for the purpose of artificial planning. If all the cutover parameter sets are all included in the same cutover plan, the user management is inconvenient due to the large number of the cutover parameter sets, and the user can create a plurality of cutover groups according to the requirement. Also, the user may select the number of parameter sets in a cutover group. The cutting or rolling back can be carried out based on the whole cutting plan, and partial cutting groups in the cutting plan can be independently selected to carry out the cutting or rolling back operation.
It can be understood that the cutover plan created by the present embodiment may be completely deleted, or only the cutover group may be deleted. When the whole cutting plan is deleted, all the cutting groups and the second parameter group in the cutting plan are removed, and the service parameters in the first parameter group are restored to the state before being added into the cutting groups. When one or more cutover groups in the cutover plan are deleted, the cutover groups and the second parameter groups in the cutover groups are cleared, and the first parameter groups in the cutover groups are restored to the state before being added into the cutover groups. Under the condition that no operation dependency relationship exists between the cutting pairs, partial cutting pairs in the cutting group can be deleted independently; in the case that there is no binding relationship between the cutover parameter groups, part of the first parameter group in the cutover group may be deleted alone.
In the method for establishing a service cutover plan according to this embodiment, a first parameter group and a second parameter group are created in the cutover plan, the cutover parameter group is used as a minimum cutover unit, and a pre-cutover service object having a dependency relationship is included in the same first parameter group, so that service parameters in a cutover service can be completely added to the cutover plan.
Referring to fig. 2, a second embodiment of the method for establishing a service cutover plan according to the present invention is proposed based on the first embodiment. In the present embodiment, the following refinement steps are included in step S20:
step S201, comparing every two service parameters in the first service to be cut, and searching the service parameters with mutual dependency relationship;
step S202, the service parameters with the dependency relationship form the first parameter group respectively.
Generally, when performing network service cutover, it is necessary to perform cutover on all service parameters in the network service, and there often exists dependency relationships between the service parameters, for example, between a working tunnel and a protection tunnel, a working tunnel OAM, a protection tunnel OAM, and a tunnel protection group, and it is necessary to form the service parameters of the service before the cutover into a first parameter group. Therefore, when creating the first parameter group, the service parameters with dependency relationship are searched for in all pre-cut services, in this embodiment, the service parameters with dependency relationship may be searched for in a pairwise comparison manner, and in other embodiments, the searching may be performed in a front-to-back search manner according to the arrangement order of the pre-cut services.
Further, step S20 further includes:
in step S203, when there is an independent service parameter having no dependency relationship with other service parameters in addition to the service parameter forming the first parameter group, the independent service parameter is used as the first parameter group.
In other embodiments, when there are independent service parameters having no dependency relationship with other service parameters in addition to the service parameters forming the first parameter group, the independent service parameters may be formed into a single first parameter group; or, when there are independent service parameters having no dependency relationship with other service parameters in addition to the service parameters forming the first parameter group, the independent parameters are randomly added to the first parameter group formed by the service parameters having the dependency relationship.
In the method for establishing a cutover plan according to this embodiment, when grouping the service parameters of the service to be cutover based on the dependency relationship, the independent service parameters that do not have dependency relationship with other service parameters are also used as the first parameter group, so as to ensure the integrity of the cutover plan.
Further, referring to fig. 3, a third embodiment of the method for establishing a service cutover plan according to the present invention is proposed based on the first embodiment. In this embodiment, after step S50, the method further includes:
step S60, binding the second service having the bearing relationship among the plurality of second parameter sets.
Because there is a certain dependency relationship between the tunnel and the emulation service having a bearer relationship during creation and deletion, for example: the tunnel must be created before the emulated service, and the emulated service must be deleted before the tunnel, so it should be noted that, when the second service is created in advance, service layer service parameters, such as a working tunnel and a corresponding protection tunnel (if any), are created first, and client layer service parameters, such as a working pseudo wire, carried on the service layer service parameters are created.
And after grouping the service parameters of the second service based on the dependency relationship, binding the service layer service parameters and the client layer service parameters with the bearing relationship among the second parameter groups. In this case, the cutover composition is a substantial cutover minimum unit, and if an error occurs during the cutover process, the entire cutover set automatically rolls back to a state before the cutover operation is started.
Referring to fig. 4, a cutover group is created by adding a simulated TDM service before cutover to the cutover group 1.1 in a non-paired manner as an example:
and searching the TDM service, the working pseudo wire, the OAM of the working pseudo wire, the protection pseudo wire, the OAM of the protection pseudo wire and the pseudo wire protection group in the simulation TDM service to form a first parameter group 1.1.1.
Adding a working tunnel based on the working pseudo wire in the first parameter group 1.1.1 to the cutover group 1.1 in a non-pairing mode, and searching an OAM (operation administration and maintenance) group, a protection tunnel and an OAM (operation administration and maintenance) group and a tunnel protection group of the working tunnel by a system to form a first parameter group 1.1.2.
Adding a working tunnel based on the protection pseudo wire in the first parameter group 1.1.1 to the cutover group 1.1 in a non-pairing mode, and searching an OAM (operation administration and maintenance) of the working tunnel, a protection tunnel, an OAM (operation administration and maintenance) of the protection tunnel and a tunnel protection group by a system to form a first parameter group 1.1.3.
A second parameter set 1.1.4 is created, which includes a working tunnel, OAM of the working tunnel, protection tunnel, OAM of the protection tunnel, tunnel protection group.
A second parameter set 1.1.5 is created, which includes a working tunnel, OAM of the working tunnel, protection tunnel, OAM of the protection tunnel, tunnel protection group.
A second parameter set 1.1.6 is created, which comprises a TDM service, a working pseudowire, an OAM of the working pseudowire, a protection pseudowire, an OAM of the protection pseudowire, a pseudowire protection group. And binding the working tunnels in the second parameter group 1.1.4 by the working pseudo wires, and binding the working tunnels in the second parameter group 1.1.5 by the protection pseudo wires. The working tunnels in the second parameter set 1.1.4 are used for carrying the working pseudowires in the second parameter set 1.1.6, and the working tunnels in the second parameter set 1.1.5 are established for carrying the protection pseudowires in the second parameter set 1.1.6.
The method for creating a cutover plan provided by this embodiment binds cutover services having a bearing relationship between cutover parameter sets, and ensures the integrity of the cutover plan.
Referring to fig. 5, a fourth embodiment of the method for establishing a service cutover plan according to the present invention is proposed based on the first embodiment. In this embodiment, after step S50, the method further includes the following steps:
step S70, forming a cutover pair by the second parameter group added to the cutover group and the first parameter group added to the cutover group.
When a user creates a cutting parameter group in a cutting group, whether the group is created or not can be judged according to own requirements, when the group is created, an instruction for forming the cutting pair is sent, and a first parameter added into the cutting group is combined with a second parameter group to form the cutting pair.
The main purpose of this embodiment is to create a cutover pair, and a first parameter set and a second parameter set are added into the cutover pair to form the cutover pair, so that the resource released by the first parameter set in the cutover pair can only be pre-paid by the paired second parameter set, and the other second parameter sets cannot be pre-paid. And a cutting pair forms a minimum cutting and replacing action, in the process, the service connection relation represented by the first parameter group is removed from the equipment and replaced by the service connection relation represented by the second parameter group, and if an error occurs in the cutting process, the cutting pair automatically rolls back to a state before the cutting operation is started.
Referring to fig. 6, a cutover group is created by adding a pre-cutover emulated ethernet private line in the cutover group, and the ethernet service, working pseudo wire, OAM of the working pseudo wire, protection pseudo wire, OAM of the protection pseudo wire, and pseudo wire protection group in the emulated ethernet private line are searched to form a first parameter group, and the first parameter group is added into a newly formed cutover pair 2.1.1.
Adding a working tunnel based on a working pseudo wire before cutting in the cutting pair 2.1.1 to the cutting group 2.1 in a group-to-group mode, searching an OAM (operation administration and maintenance) and a protection tunnel of the working tunnel by a system, forming a first parameter group by protecting the OAM and the tunnel protection group of the tunnel, and adding the first parameter group into a newly formed cutting pair 2.1.2.
Adding a working tunnel based on which the pseudo wire is protected before the cutting in the cutting pair 2.1.1 to the cutting group 2.1 in a group-to-group mode, searching an OAM (operation administration and maintenance) and a protection tunnel of the working tunnel by a system, forming a first parameter group by the OAM and the tunnel protection group of the protection tunnel, and adding the first parameter group into a newly formed cutting pair 2.1.3.
And creating a second parameter group for the cut-over pair 2.1.2, wherein the second parameter group comprises a cut-over work tunnel, OAM of the work tunnel, a protection tunnel, OAM of the protection tunnel and a tunnel protection group.
And creating a second parameter group for the cut-over pair 2.1.3, wherein the second parameter group comprises a cut-over work tunnel, OAM of the work tunnel, a protection tunnel, OAM of the protection tunnel and a tunnel protection group.
And creating a second parameter group for the cut-over pair 2.1.1, wherein the second parameter group comprises the Ethernet private line service after cut-over, the working pseudo-line, the OAM of the working pseudo-line, the protection pseudo-line, the OAM of the protection pseudo-line and the pseudo-line protection group. Wherein, the cut-off working tunnel in the working pseudo wire binding cut-off pair 2.1.2 protects the cut-off working tunnel in the pseudo wire binding cut-off pair 2.1.3.
For the cutover pairs in the cutover group, provided that there is no operational dependency between them, such as: all the pairs are emulation service cutover pairs, or although the tunnel cutover pair and the emulation service cutover pair exist at the same time, the tunnel cutover pair and the emulation service cutover pair do not have a bearing relationship, and then the cutover or rollback can be initiated for a single cutover pair at the moment.
It can be understood that the user may create a hybrid cutover group according to the requirement, and in the cutover group, the first parameter group and the second parameter group may be created to be paired or not paired to adapt to various cutover requirements in the network operation and maintenance.
The method for creating a cutover plan provided by the embodiment creates the first parameter group and the second parameter group in a pairing mode, so that the resource sharing range is more controllable, the control granularity of cutover and rollback actions is finer, the method is flexible and convenient, and the cutover parameter groups can be flexibly paired or not paired as required, thereby being suitable for various cutover requirements in network operation and maintenance.
The invention also provides a device for establishing the service cutover plan.
Referring to fig. 7, a functional module diagram of a first embodiment of the apparatus for creating a service cutover plan according to the present invention is shown.
In this embodiment, the apparatus for establishing a service cutover plan includes:
a cutover group module 10 for creating a cutover group in a cutover plan.
The first grouping module 20 is configured to divide the service parameters into a plurality of first parameter groups based on a dependency relationship between the service parameters in the first service to be cutover.
A first adding module 30, configured to add the first parameter group to the created cutover group.
Before network cutover, a complete cutover plan needs to be created, and the cutover plan includes a complete service parameter of a first service to be cutover and a service parameter of a second service created in advance. The first service refers to a service already existing in the existing network before the execution of the cutover action, and the second service refers to a service which is pre-established in the network management and is ready to replace the first service in the cutover process.
In the present embodiment, a cutover plan for establishing a PTN network is taken as an example for explanation, and in other embodiments, other network cutover may be performed. The PTN network includes various emulated services, such as emulated ethernet services, emulated TDM (time-division multiplexing) services, etc., and generally, there is a complex dependency relationship between service parameters in the services to be cut, and these parameters cannot be separated during the cutting. For example, the service parameters such as ethernet service in the emulated ethernet service, working pseudo wire on which the ethernet service depends, OAM of the working pseudo wire, protection pseudo wire, OAM of the protection pseudo wire, and pseudo wire protection group. In this embodiment, the cut-over parameter group is used as a minimum unit for resource sharing, when a cut-over plan is created, the cut-over group module 10 creates a cut-over group in the cut-over plan, and the first grouping module 20 divides the service parameters into a plurality of first parameter groups based on the dependency relationship among the services in the first services to be cut over, for example, each unprotected tunnel to be cut over and its OAM configuration (if any) form one cut-over parameter group; each pair of working, protection tunnel and its OAM configuration (if any), protection group configuration (if any) together form a cutover parameter set; each emulation service to be cutover, along with its working pseudowire/working multi-segment pseudowire, protection pseudowire/protection multi-segment pseudowire (if any), pseudowire OAM configuration (if any), pseudowire protection group configuration (if any), collectively form a cutover parameter set, which the first adding module 30 adds to the cutover plan created by the cutover group module 10.
The method comprises the steps of establishing a relation table among a plurality of service parameters of the service to be cut, judging the dependence relation, and judging the dependence relation according to the relation table when grouping.
And the second grouping module 40 is configured to group the service parameters into a plurality of second parameter groups based on the pre-created dependency relationship between the service parameters in the second service.
A second adding module 50, configured to add the second parameter set to the created cutover group.
The parameter set is an atomic unit that cannot be subdivided in the segmentation process, and is divided into a first parameter set and a second parameter set. The first parameter group refers to the parameter group of the service to be cut existing in the network before the cutting action is executed, and the second parameter group refers to the parameter group which is pre-established in the network management and is ready to replace the first parameter group in the cutting process. In a cutover group, after confirming that the creation of the first parameter group is completed, the second grouping module 40 groups the service parameters in the pre-created second service into a plurality of second parameter groups based on the dependency relationship, and the second adding module 50 adds the second parameter groups into the cutover group.
In the present embodiment, the first parameter group and the second parameter group may be paired or not paired. If the parameters are paired, the resources released by the first parameter set in the cutting-over pair can only be pre-supported by the paired second parameter set, and other second parameter sets can not be pre-supported. And a cutting pair forms a minimum cutting and replacing action, in the process, the service connection relation represented by the first parameter group is removed from the equipment and replaced by the service connection relation represented by the second parameter group, and if an error occurs in the cutting process, the cutting pair automatically rolls back to a state before the cutting operation is started.
If the cutover parameter group is directly added into the cutover group under the condition of no pair, at this time, the resource is shared in the whole range of the cutover group, that is, the resource released by any first parameter group in the group can be pre-supported by any second parameter group in the cutover group.
Further, after completing creation of a cutover group, the user may determine whether to continue to create the cutover group in the cutover plan according to the requirement, and if the cutover group needs to continue to be created, continue to create the cutover group until the cutover plan is completed.
It should be noted that a plurality of cutover groups may together form a cutover plan. The various cutting groups in the cutting plan have no operational interdependence relationship, and the cutting plans are formed by the cutting groups and are more used for the purpose of artificial planning. If all the cutover parameter sets are all included in the same cutover plan, the user management is inconvenient due to the large number of the cutover parameter sets, and the user can create a plurality of cutover groups according to the requirement. Also, the user may select the number of cutover parameter sets in a cutover group. The cutting or rolling back can be carried out based on the whole cutting plan, and partial cutting groups in the cutting plan can be independently selected to carry out the cutting or rolling back operation.
It can be understood that the cutover plan created by the present embodiment may be completely deleted, or only the cutover group may be deleted. When the whole cutting plan is deleted, all the cutting groups and the second parameter group in the cutting plan are removed, and the service parameters in the first parameter group are restored to the state before being added into the cutting groups. When one or more cutover groups in the cutover plan are deleted, the cutover groups and the second parameter groups in the cutover groups are cleared, and the first parameter groups in the cutover groups are restored to the state before being added into the cutover groups. Under the condition that no operation dependency relationship exists between the cutting pairs, partial cutting pairs in the cutting group can be deleted independently; in the case that there is no binding relationship between the cutover parameter groups, part of the first parameter group in the cutover group may be deleted alone.
The apparatus for creating a service cutover plan according to this embodiment creates a first parameter group and a second parameter group in the cutover plan, takes the cutover parameter group as a minimum cutover unit, and incorporates a pre-cutover service object having a dependency relationship into the same first parameter group, so that the service parameters in the cutover service can be completely added to the cutover plan.
Referring to fig. 8, a second embodiment of the apparatus for establishing a service cutover plan according to the present invention is proposed based on the first embodiment. In the present embodiment, the first grouping module 20 includes the following refinement units:
the searching unit 210 is configured to compare every two service parameters in the first service to be cutover, and search the service parameters having a dependency relationship with each other;
an adding unit 220, configured to form the first parameter group with the service parameters having the dependency relationship with each other, respectively.
Generally, when performing network service cutover, it is necessary to perform cutover on all service parameters in the network service, and there often exists dependency relationships between the service parameters, for example, between a working tunnel and a protection tunnel, a working tunnel OAM, a protection tunnel OAM, and a tunnel protection group, and it is necessary to form the service parameters of the service before the cutover into a first parameter group. Therefore, when creating the first parameter group, the service parameters with dependency relationship are searched in all pre-cutover services, in this embodiment, the searching unit 210 searches the service parameters with dependency relationship in a pairwise comparison manner, and the adding unit 220 adds them into the created cutover group. In other embodiments, the search may be performed in a front-to-back search manner according to the ranking order of the services before the cutting.
Further, the first grouping module 20 further includes:
an independent parameter unit 203, configured to take the independent service parameter as the first parameter group when there is an independent service parameter that has no dependency relationship with other service parameters, in addition to the service parameter forming the first parameter group.
In other embodiments, the independent parameter unit 203 may also form the independent service parameters into a single first parameter group when there are independent service parameters that have no dependency relationship with other service parameters in addition to the service parameters forming the first parameter group; alternatively, when there is an independent service parameter that has no dependency relationship with any other service parameter in addition to the service parameter forming the first parameter group, the independent parameter unit 203 randomly adds the independent parameter to the first parameter group formed by the service parameters having the dependency relationship.
The apparatus for creating a cutover plan according to this embodiment, when grouping the service parameters of the service to be cutover based on the dependency relationship, similarly uses the independent service parameters that do not have dependency relationship with other service parameters as the first parameter group, thereby ensuring the integrity of the cutover plan.

step S60, binding the second service having the bearing relationship among the plurality of second parameter sets.
Because there is a certain dependency relationship between the tunnel and the emulation service having a bearer relationship during creation and deletion, for example: the tunnel must be created before the emulated service, and the emulated service must be deleted before the tunnel, so it should be noted that, when the second service is created in advance, service layer service parameters, such as a working tunnel and a corresponding protection tunnel (if any), are created first, and client layer service parameters, such as a working pseudo wire, carried on the service layer service parameters are created.
And after grouping the service parameters of the second service based on the dependency relationship, binding the service layer service parameters and the client layer service parameters with the bearing relationship among the second parameter groups. In this case, the cutover composition is a substantial cutover minimum unit, and if an error occurs during the cutover process, the entire cutover set automatically rolls back to a state before the cutover operation is started.

And binding the working tunnels in the second parameter group 1.1.4 by the working pseudo wires, and binding the working tunnels in the second parameter group 1.1.5 by the protection pseudo wires. The working tunnels in the second parameter set 1.1.4 are used for carrying the working pseudowires in the second parameter set 1.1.6, and the working tunnels in the second parameter set 1.1.5 are established for carrying the protection pseudowires in the second parameter set 1.1.6.
The apparatus for creating a cutover plan provided in this embodiment binds cutover services having a bearing relationship between cutover parameter sets, so as to ensure the integrity of the cutover plan.

The main purpose of this embodiment is to create a cutover pair, and a first parameter set and a second parameter set are added into the cutover pair to form the cutover pair, so that the resource released by the first parameter set in the cutover pair can only be pre-paid by the paired second parameter set, and the other second parameter sets cannot be pre-paid. And a cutting pair forms a minimum cutting and replacing action, in the process, the service connection relation represented by the first parameter group is removed from the equipment and replaced by the service connection relation represented by the second parameter group, and if an error occurs in the cutting process, the cutting pair automatically rolls back to a state before the cutting operation is started.
Referring to fig. 6, a cutover group is created by adding a pre-cutover emulated ethernet private line in the cutover group, and the ethernet service, working pseudo wire, OAM of the working pseudo wire, protection pseudo wire, OAM of the protection pseudo wire, and pseudo wire protection group in the emulated ethernet private line are searched to form a first parameter group, and the first parameter group is added into a newly formed cutover pair 2.1.1.

Wherein, the cut-off working tunnel in the working pseudo wire binding cut-off pair 2.1.2 protects the cut-off working tunnel in the pseudo wire binding cut-off pair 2.1.3.
For the cutover pairs in the cutover group, provided that there is no operational dependency between them, such as: all the pairs are emulation service cutover pairs, or although the tunnel cutover pair and the emulation service cutover pair exist at the same time, the tunnel cutover pair and the emulation service cutover pair do not have a bearing relationship, and then the cutover or rollback can be initiated for a single cutover pair at the moment.
