Description

一种实现业务迁移的方法及装置Method and device for realizing business migration 技术领域Technical field
本文涉及但不限于网络管理技术，尤指一种实现业务迁移的方法及装置。This document relates to, but is not limited to, network management technology, and more particularly to a method and apparatus for implementing service migration.
背景技术Background technique
随着信息时代的到来，为了让用户享受到高质量的网络，通讯运营商向用户提供端到端的业务服务。运营商在使用网管软件创建端到端的业务后，需要保证业务稳定连续工作。在实际应用中，由于网络拓扑经常发生变迁，例如：设备搬迁、设备替换、节点内的单板迁移和端口迁移等，要保证网络变迁时业务不中断，需要将业务迁移到变迁后可用的网络中。当前，业务迁移的方法主要通过技术人员通过逐条的修改业务，将每条业务重新指定路由路径进行业务迁移，业务迁移需要满足路由约束为：禁止经过变迁前网络拓扑，必须经过变迁后网络拓扑。With the advent of the information age, in order to allow users to enjoy high-quality networks, communication operators provide end-to-end business services to users. After the network management software is used to create end-to-end services, the carrier needs to ensure stable and continuous service. In the actual application, the network topology is frequently changed, for example, equipment relocation, equipment replacement, board migration and port migration in the node, etc., to ensure that services are not interrupted during network transition, and services need to be migrated to the network after the transition. in. Currently, the service migration method is performed by the technical personnel to modify the service one by one, and each service is re-designated with a routing path to perform service migration. The service migration needs to meet the routing constraint: the network topology before the transition is prohibited, and the network topology after the transition must pass.
相关的业务迁移方法存在以下问题：1、在业务量巨大的情况下，单条修改业务要耗费大量的时间和人力，无法满足业务迁移的时限要求；2、人工修改业务的路由约束，存在选错路由的问题；3、人为进行单条业务修改存在关联业务被遗漏而导致关联业务中断的问题；4、没有提示需要搬迁哪些设备、单板或端口，设备维护人员很容易误操作，导致业务中断。当前的网络管理技术还提供了其它业务迁移功能，包括：扩容、缩容、业务割接、网元内端口迁移等，但是应用范围都很受限。扩容只适用于增加网元的情况；缩容只适用于减少网元的情况；业务割接只适用于指定业务的切换；网元内端口迁移只适用于同一网元内部的业务迁移。The related service migration methods have the following problems: 1. In the case of a large amount of traffic, a single modification of the service takes a lot of time and manpower, and cannot meet the time limit of the service migration; 2. The routing constraint of manually modifying the service has a wrong selection. The problem of routing; 3. The problem of the interruption of the associated service due to the omission of the associated service is caused by the failure of the associated service; 4. The device maintenance personnel are easily mishandled and the service is interrupted because there is no indication of which devices, boards or ports need to be relocated. The current network management technology also provides other service migration functions, including: capacity expansion, capacity reduction, service cutover, and intra-network port migration, but the application scope is limited. The capacity expansion is only applicable to the situation where the NE is added. The capacity reduction is only applicable to the network element. The service switching is only applicable to the switching of the specified service. The port migration in the NE is only applicable to the service migration within the same NE.
综上，相关的业务迁移方法由于单条修改业务复杂，在时间、准确性、关联业务处理及误操作的问题，网络管理技术的其他业务迁移功能，只针对不同种类的特殊情况进行分别处理，并不适合拓扑变迁时，可能出现多种情况的业务迁移。In summary, the related service migration method is complicated by different services, and the other business migration functions of the network management technology are processed separately for different types of special situations in terms of time, accuracy, associated service processing, and misoperation. When it is not suitable for topology transition, there may be multiple situations of business migration.

下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.
图1为本发明实施例实现业务迁移的方法的流程图，如图1所示，包括：FIG. 1 is a flowchart of a method for implementing service migration according to an embodiment of the present invention. As shown in FIG. 1 , the method includes:
步骤100、根据需要进行业务迁移的路由的起始节点和终止节点，遍历拓扑变迁前起始节点和终止节点相同的所有业务；Step 100: Start and terminate the route of the service migration according to the requirement, and traverse all the services of the same start node and the terminating node before the topology transition;
本步骤中，遍历拓扑变迁前起始节点和终止节点相同的所有业务。这里，遍历过程主要针对业务数据服务器中包含有网络拓扑中的所有业务信息，业务数据服务器为相关的服务器。In this step, all services with the same starting node and terminating node before the topology transition are traversed. Here, the traversal process is mainly for the business data server including all the business information in the network topology, and the business data server is the related server.
可选的，本步骤之前还包括：Optionally, before this step, it also includes:
网络拓扑变迁时，确定需要进行业务迁移的路由的起始节点和终止节点。 When the network topology changes, determine the start node and the termination node of the route that needs to perform service migration.
其中，需要进行业务迁移的路由的起始节点即步骤100中的起始节点，需要进行业务迁移的路由的终止节点即步骤100中的终止节点。The starting node of the route that needs to perform the service migration is the starting node in step 100, and the terminating node of the route that needs to perform the service migration is the terminating node in step 100.
其中，通讯运营商根据业务的起点和终点，确定需要进行业务迁移的路由的起始节点和终止节点。业务的起点就是需要进行业务迁移的路由的起始节点，业务的终点就是需要进行业务迁移的路由的终止节点。The communication carrier determines the start node and the termination node of the route that needs to perform service migration according to the starting point and the end point of the service. The starting point of the service is the starting node of the route that needs to be migrated, and the end point of the service is the terminating node of the route that needs to perform service migration.
步骤101、从遍历的起始节点和终止节点相同的所有业务中确定进行迁移的业务；Step 101: Determine a service to be migrated from all services in which the traversed start node and the terminating node are the same;
需要说明的是，确定进行迁移的业务主要根据成本、地理环境、施工条件、业务本身需求等进行判断确定，对于不同用户而言，其参考的因素往往不同，因此需要技术人员对遍历出来的所有业务进行分析判断，遍历出所有业务的同时，相当于向用户直接或间接显示了上述信息，或者本领域技术人员也可以将相关参考信息进行整理显示，供用户查看，进而确定进行迁移的业务。It should be noted that the business that determines the migration is mainly determined according to the cost, geographical environment, construction conditions, and the needs of the business itself. For different users, the reference factors are often different, so all the technicians need to traverse. The service performs analysis and judgment, and traverses all the services, which is equivalent to directly or indirectly displaying the above information to the user, or the related art information can be displayed and displayed by the user for viewing by the user, thereby determining the service to be migrated.
步骤102、根据确定进行迁移的业务的外键，查询获得迁移相关参数信息；这里，查询过程主要针对业务数据服务器进行，获得迁移相关参数信息。In step 102, the query obtains the migration related parameter information according to the foreign key of the service that is determined to be migrated. The query process is performed on the service data server to obtain the migration related parameter information.
可选的，迁移相关参数信息包括：确定进行迁移的业务的工作保护关系、带宽共享关系和业务迁移后网络拓扑的带宽资源使用率。Optionally, the mobility related parameter information includes: determining a working protection relationship of the service to be migrated, a bandwidth sharing relationship, and a bandwidth resource usage rate of the network topology after the service migration.
步骤103、根据查询获得的迁移相关参数信息指定迁移的业务的路由约束到变迁后的网络拓扑中；Step 103: Specify, according to the migration related parameter information obtained by the query, a routing constraint of the migrated service to the network topology after the transition;
需要说明的是，指定迁移的业务的路由约束到变迁后的网络拓扑主要是向用户显示查询获得的迁移相关参数信息后，用户根据迁移相关参数信息进行路由分析后，输入外部指令指定迁移的业务的路由约束到变迁后的网络拓扑中。It should be noted that after the route constraint of the specified service is changed to the network topology after the transition, the user displays the migration-related parameter information obtained by the query, and after the route analysis is performed according to the migration-related parameter information, the user inputs the external command to specify the migrated service. The routing is constrained to the network topology after the transition.
本步骤中，迁移的业务的路由约束包括迁移的业务的路由必须经过(或禁止经过)某个网元、某块单板、或某个端口等。In this step, the route constraint of the migrated service includes the route of the migrated service, or the egress of a certain network element, a board, or a port.
步骤104、根据指定约束路由进行路由计算后，确定进行迁移的业务的迁移。 Step 104: After performing route calculation according to the specified constraint route, determine the migration of the migrated service.
可选的，完成确定进行迁移的业务的迁移后，本发明实施例方法还包括：Optionally, after the method for determining the migration of the migrated service is completed, the method of the embodiment of the present invention further includes:
反馈业务迁移完成的信息，根据业务迁移完成的信息，对拓扑变迁涉及的设备、和/或单板、和/或端口进行变迁硬件的迁移处理。The information about the completion of the service migration is processed by the migration hardware of the device, and/or the board, and/or the port involved in the topology change according to the information about the service migration.
其中，业务迁移完成的信息包括：变迁前网络拓扑上的设备、单板或端口已经失效。The information about the completion of the service migration includes the failure of the device, board, or port on the network topology before the transition.
其中，进行变迁硬件的迁移出来包括：进行设备、单板或端口的搬迁操作。The migration of the transition hardware includes: performing the relocation operation of the device, the board, or the port.
本发明方法由于遍历获得了拓扑变迁前起始节点和终止节点相同的所有业务，从中确定进行迁移的业务，避免了关联业务的错漏；通过外键查询迁移相关参数信息，快速而准确的实现了路由约束的指定，降低了单条修改业务的复杂度。对不同种类的业务均可进行迁移，提高了业务迁移的效率。The method of the present invention obtains all the services of the same starting node and the terminating node before the topology transition, and determines the service to be migrated from the traversal, thereby avoiding the error of the associated service; and the parameter information of the migration through the foreign key query, which is quickly and accurately realized.
