Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present invention relates to a method for upgrading a network element. The network element module in this embodiment is set on the SBA framework, and based on the SBA framework, the designed system for upgrading the network element includes: the system comprises a centralized network element network management system, a load balancer, a registration center and at least one network element module. To facilitate understanding of embodiments of the present invention, the SBA architecture is first described.
The centralized network element network management system is in communication connection with a registration center, the registration center is in communication connection with a load balancer, the load balancer is connected with each network element module in the SAB architecture, and the architecture of the SBA is shown in FIG. 1.
Since the SBA architecture virtualizes each function, the SBA architecture includes a plurality of network element systems, and each network element system has at least one network element module. Each network element module comprises at least 2 network element units of the same type, each network element unit is a network element component virtualized through network functions, in an SBA architecture, the network element units of the same type can realize the same service functions, and system files operated by the network element structures of the same type are the same. In order to efficiently reduce the damage when the upgrade error occurs, each network element unit is provided with one-to-one corresponding upgrade agents. The upgrade agent may be deployed in the network element module in the form of a virtual machine. In addition, as shown in fig. 1, the SBA architecture may further be provided with a file server, and the file server may be respectively connected to the centralized network element network management system and the upgrade agent of each network element unit. The file server may be used to store upgrade information, which may include system files or patch files to be upgraded.
It should be noted that the registry may be deployed in the network element system, or may be deployed outside the network element system. If the registry is deployed in the network element system, the registry can register each network element unit in the network element system, and if the registry is deployed outside the network element system, the registry can register and manage the network element units in the multiple network element systems, wherein the network element units have various forms, and can be application program interfaces with special functions or applications with special functions. In this example, the API is used as a network element unit to introduce the upgrading process for the network element module.
In this example, a registry is deployed in the network element system for registering and managing each network element unit in the network element system. The specific flow of the network element upgrading method is shown in fig. 2.
Step 101: and obtaining an upgrading instruction of the network element module to be upgraded, wherein the network element module to be upgraded comprises at least 2 network element units of the same category.
Specifically, the centralized network element management system is used for centrally managing each network element module and the registration center. The user can upload the upgrade information to the centralized network element network management system, and the upgrade information comprises: after the centralized element network management system receives the upgrade information, the upgraded system file or patch file configures corresponding version information for the received upgrade information, and stores the upgrade information and the corresponding version information in the centralized element network management system, such as in a database. After uploading the system file or the patch file to be upgraded, the user can set an upgrade scheme for the network element module to be upgraded according to actual needs, or the centralized network element management system can designate a corresponding upgrade scheme according to the network element module to be upgraded, wherein the upgrade scheme includes the upgraded system file or the patch file and corresponding version information. The centralized network element network management system sends an upgrading instruction to the registration center according to the upgrading scheme, the registration center receives the upgrading instruction sent by the centralized network element network management system, and simultaneously the centralized network element network management center sends upgrading information and corresponding version information to the file server, and the file server stores the version information corresponding to the upgrading information.
It should be noted that, because the version information of each network element unit in the same network element module is the same, the centralized network element network management system may send the upgrade instruction to the upgrade agent corresponding to each network element unit.
Step 102: the following processing is carried out for each network element unit: and sending a service migration instruction to the load balancer according to the upgrading instruction so that the load balancer migrates the services of the network element unit to other network element units of the same category, and upgrading the network element unit by the upgrading agent after the upgrading agent corresponding to the network element unit determines that the service migration is finished.
Specifically, each network element module includes at least 2 network element units, and upgrading the network element module requires upgrading each network element unit. The registry may discover the upgrade agent for each network element registered with the registry. The upgrading instruction comprises the following steps: version information, identification information of the network element module to be upgraded, and the like. The registry performs the following processing for each network element unit: and sending a service migration instruction to the load balancer according to the upgrading instruction, and migrating the service in the network element unit. For example, a network element module B to be upgraded includes two network element units, which are API1 and API2, respectively, if API2 is upgraded first, the registration center sends a service migration instruction for service migration to API2 to the load balancer, after receiving the service migration instruction for service in migration API2, the load balancer detects whether there is service traffic being processed in API2, if so, the load balancer may re-detect or wait to receive the prompt information sent by API2 after the service processing is completed after a preset time interval, and after detecting that there is no service processing or receiving the prompt information that the service processing is completed again, the load balancer transfers the subsequent service traffic to API1 of the same category to implement service migration. If the API2 is detected to have no service traffic being processed, the subsequent service traffic is directly transferred to the API1 of the same category, and the service migration is completed. It can be understood that if there are three network element units of the same category, the service of the network element unit to be upgraded can be transferred to any one of the other network element units of the same category.
After the API2 service migration is completed, after the upgrade agent corresponding to the API2 receives a service migration completion instruction sent by the load balancer, upgrade information is obtained according to the upgrade instruction, where the upgrade information includes: and storing the files to be upgraded or the patch files. If the file to be upgraded or the patch file is stored in the database of the network element module, the upgrade agent directly extracts the file to be upgraded or the patch file from the database of the network element module, and if the file to be upgraded or the patch file is stored in the file server, the file to be upgraded or the patch file can be downloaded from the file server according to the version information in the upgrade instruction. And the upgrading agent upgrades the network element unit according to the acquired upgrading information.
In an example, before the upgrade of the network element unit, the upgrade agent corresponding to the network element unit may backup the system file in the network element unit, and after the backup is completed, upgrade the network element unit, and if the upgrade fails, the upgrade agent will read the backed-up system file again and rerun the backed-up system file.
In one example, after determining that the network element is upgraded, a traffic restoration instruction is sent to the load balancer to divert migrated traffic back to the network element by the load balancer. For example, if the upgrade to API2 is completed, the registry sends a traffic restoration instruction to the load balancer, which, upon receiving the traffic restoration instruction, transfers subsequent traffic back to API 2.
It can be understood that after the upgrade is completed for each network element in the network element module, the upgrade for the network element module is finished.
The whole network element upgrading process is described below with reference to fig. 1:
the centralized network element network management system executes S0, sends the upgrade information and the version information to the file server, and the file server stores the upgrade information and the version information; the centralized network element network management system executes the step S1, issues an upgrading instruction to the registration center, and simultaneously executes the step S2, and sends the upgrading instruction to an upgrading agent of the API 2; after receiving the upgrade instruction, the upgrade agent of the API2 performs step S3 to download corresponding upgrade information from the file server according to the version information in the upgrade instruction. After receiving the upgrade instruction, the registry performs step S4 to send a service migration instruction to the API2 to the load balancer; the load balancer executes step S5 to transfer the traffic flow from the API2 to the API 1; after determining that the service transfer in the API2 is completed, the upgrade agent performs step S6 to upgrade the API2 according to the upgrade information.
Compared with the prior art, the network element module to be upgraded comprises at least two network element units of the same type, the upgrading operation is respectively carried out on each network element unit, the service on the current network element unit is transferred to other network elements of the same type by sending a service migration instruction to the load balancer, an additional backup network element module is not required to be reset, the service flow of the network element module to be upgraded is backed up, and the cost and the complexity of network element upgrading are reduced; meanwhile, the service of the network element unit is migrated before upgrading, so that the problem of service interruption in the upgrading process is solved, the network element equipment does not need to be modified due to the adoption of a software upgrading mode, the difficulty of network element upgrading is reduced, the network element is not needed to be upgraded on site manually due to the adoption of software upgrading, and the upgrading efficiency is improved.
A second embodiment of the present invention relates to a method for upgrading a network element. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in a second embodiment of the present invention, the automatic upgrade of the expanded network element module is performed. The specific flow of the network element upgrading method is shown in fig. 3.
Step 201: and receiving a registration request of the newly added network element module, wherein the registration request comprises the version information of the newly added network element module.
Specifically, in the SBA architecture, a network function software manager (VNFM) may be used to perform capacity expansion, and the upgrade agents of each network element unit in the newly added network element module obtain version information of the system file operated by each network element unit, and send a registration request to the registration center, where the registration request includes: the version information of the newly added network element module; certainly, for each network element unit of the same category in the same newly added network element module, the version of the system file operated is the same, and the registration request sent by the upgrade agent corresponding to each network element unit can be used as the registration request of the newly added network element module. The registration center receives the registration request of the newly added network element module.
Step 202: and judging whether the version information of the newly added network element module belongs to the latest version information, if so, executing the step 203, and otherwise, executing the step 204.
Specifically, the registry detects whether the version information of the system file running in the newly added network element module belongs to the latest version information, if so, step 203 is executed, otherwise, step 204 is executed. For example, if the version information of the system file running in the network element module APIV1 is V1 and the latest version information is V2, it is determined that the version information of the newly added network element module is not the latest version information.
Step 203: and if the version information is determined to be the latest version information, registering the newly added network element module.
Specifically, if the version information is determined to be the latest version information, the information of the network element module is registered, and the newly added network element module is allowed to access the registration center, so that the registration center can discover and manage the upgrade agents corresponding to each network element unit in each network element module.
Step 204: and if the version information is determined to belong to the old version information, determining the newly added network element module as the network element module to be upgraded.
Step 205: and obtaining an upgrading instruction of the network element module to be upgraded.
In one example, after determining that the newly added network element module is the network element module to be upgraded, the registration center directly generates an upgrade instruction of the network element module to be upgraded. The upgrade instruction includes an identifier of the newly added network element module, latest version information, and the like.
Step 206: the following processing is carried out for each network element unit: and sending a service migration instruction to the load balancer according to the upgrading instruction so that the load balancer migrates the services of the network element unit to other network element units of the same category, and upgrading the network element unit by the upgrading agent after the upgrading agent corresponding to the network element unit determines that the service migration is finished.
This step is substantially the same as step 102 in the first embodiment, and will not be described herein.
The following describes the process of automatically performing network element upgrade under the condition of capacity expansion with reference to fig. 4:
a VNFM executing step S21, where a network element module with a system file version of V1 is expanded, the network element module includes two network element units, the network element unit takes API as an example, the network element module includes API1 and API2, the upgrade agent of API1 executes step S22, a registration request is initiated to a registration center, the registration request includes currently used version information, the registration center detects that the version information is not the latest version information, then it determines that the newly added network element module is a network element module to be upgraded, and then the registration center executes step S23, generates an upgrade instruction, and sends the upgrade instruction to the upgrade agent of API 1; the registry also executes step S24, and sends a service migration instruction to the load balancer; after receiving the service migration instruction, the load balancer migrates the service in the API1 to the API2, since the API1 is not used at this time, the load balancer may directly migrate the service to the API2, and then the upgrade agent of the API1 downloads the upgrade information from the file server, and performs step S26, and upgrades the API1 according to the upgrade information. Similarly, the API2 is upgraded according to the process, and the upgrade of the newly added network element module is completed.
In the method for upgrading a network element provided in this embodiment, the registry may automatically detect version information of the newly added network element module under the condition of capacity expansion, and if it is detected that the version information of the newly added network element module belongs to the old version information, the newly added network element module is automatically upgraded without manual intervention, thereby improving the efficiency of network element upgrading.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
A third embodiment of the present invention relates to a method for upgrading a network element, where a network element module to be upgraded includes at least two network element units of the same category, each network element unit has a corresponding upgrade agent, and the method for upgrading a network element is applied to an upgrade agent, and a specific flow of the method for upgrading a network element is shown in fig. 5.
Step 301: and determining the upgrading information of the network element unit according to the upgrading instruction of the network element module to be upgraded.
The system comprises a centralized network element network management system, a registration center, a load balancer and an SBA architecture, wherein the centralized network element network management system is in communication connection with the registration center, the registration center is in communication connection with the load balancer, the load balancer is connected with each network element module in the SAB architecture, each function is virtualized by the SBA architecture, so that the SBA architecture comprises a plurality of network element systems, and each network element system comprises at least one network element module. Each network element module comprises at least 2 network element units of the same type, each network element unit is a network element component virtualized through network functions, in an SBA architecture, the network element units of the same type can realize the same service functions, and system files operated by the network element units of the same type are the same. In order to reduce the damage caused by the occurrence of the upgrade error, each network element unit is provided with a one-to-one corresponding upgrade agent, and the network element unit is used for realizing the designated function and can have various forms, for example, an application program interface or an application. The upgrade agent may be deployed in the network element module in the form of a virtual machine.
The upgrading instruction can be issued by a centralized network element network management system or a registration center. If the centralized network element network management system determines the network element module to be upgraded, the centralized network element network management system can issue an upgrading instruction to the registration center and the upgrading agent of each network element unit in the network element module to be upgraded. Or after the register center receives the upgrade order, the register center sends the upgrade order to the upgrade agent of the network element unit of the network element module to be upgraded.
In another example, for the newly added network element module obtained by capacity expansion, if the registration center determines that the newly added network element module is the network element module to be upgraded, the registration center generates an upgrade instruction and issues the upgrade instruction to the upgrade agent.
In the SBA architecture, a network function software manager (VNFM) may be used to perform capacity expansion, and the upgrade agents of each network element unit in the newly added network element module obtain version information of the system file operated by each network element unit, and send a registration request to the registration center, where the registration request includes: the version information of the newly added network element module; certainly, for each network element unit of the same category in the same newly added network element module, the version of the system file operated is the same, and the registration request sent by the upgrade agent corresponding to each network element unit can be used as the registration request of the newly added network element module. The registration center receives the registration request of the newly added network element module. The registration center detects whether the version information of the newly added network element module belongs to the latest version information, and if so, the newly added network element module is registered. If the version information is determined to belong to the old version information, determining the newly added network element module as the network element module to be upgraded; for example, if the version information of the system file operated in the network element module APIV1 is V1 and the latest version information is V2, it is determined that the version information of the system file operated by the newly added network element module is not the latest version information.
After the upgrade agent of each network element unit of the network element module to be upgraded receives the upgrade instruction, the upgrade information can be downloaded from the file server according to the version information in the upgrade instruction, and the upgrade information includes an upgrade file or a patch file and is used for upgrading the network element unit.
In addition, for each network element unit of the network element module to be upgraded, the registration center sends a service migration instruction of the network element unit to the load balancer, the service in the network element unit is migrated to other network element units of the same type, and after the load balancer migrates the service traffic of the network element unit, the registration center sends prompt information of the completion of service migration to the upgrade agent of the network element unit.
