Description

一种在分组传送网中处理环网路径的方法、 网管及节点设备  Method, network management and node device for processing ring network path in packet transport network
技术领域 Technical field
本发明涉及 PTN (分组传送网, Packet Transport Network )传输设备的扩 缩环功能, 并且特别的, 涉及一种在分支传送网环型网络中不中断业务的处 理环网路径的方法、 信息处理方法、 网管及节点设备。  The present invention relates to a scaling loop function of a PTN (Packet Transport Network) transmission device, and in particular, to a method and an information processing method for processing a ring network path without interrupting services in a branch transport network ring network , network management and node equipment.
背景技术 Background technique
随着网络规模和数据业务量的不断增加, 需要传输网提供越来越大的传 输能力; 为了满足用户的需求, 传输产品需要提供较高的可扩展性, 包括容 量的扩展性和业务扩展性等。 而分组传输正好能够满足这种需求, 所以得到 了迅速发展。 在分组传输网中常用的技术是 T-MPLS (传送多协议标签交 换) , 它是 ITU-T (国际电信联盟远程通信标准化组织)标准化的一种分组 传送网技术, 是去掉了 MPLS ( Multi-Protocol Label Switching, 多协议标签交 换) 的 ip 无连接转发特性、 同时增加了端到端的 OAM ( Operation Administration and Maintenance, 操作、 管理和维护)和保护功能而形成的一 种传送协议。 在 T-MPLS传送网络中通常釆用网状拓朴结构, 在实际部署中 也证明: 环的应用和需求是十分普遍的, 所以环网的扩缩环功能也十分重 要。  As the network scale and data traffic continue to increase, the transmission network is required to provide more and more transmission capabilities. To meet the needs of users, transmission products need to provide high scalability, including capacity scalability and service scalability. Wait. Packet transmission is just enough to meet this demand, so it has developed rapidly. A commonly used technology in packet transmission networks is T-MPLS (Transport Multi-Protocol Label Switching), which is a packet transport network technology standardized by ITU-T (International Telecommunication Union Telecommunication Standardization Organization), which removes MPLS (Multi- Protocol Label Switching, Multi-Protocol Label Switching) A transport protocol that combines the ip connectionless forwarding feature with the addition of end-to-end OAM (Operation Administration and Maintenance) and protection. In the T-MPLS transport network, the mesh topology is usually used. In actual deployment, it is also proved that the application and requirements of the ring are very common, so the expansion and contraction function of the ring network is also very important.
在传统的 SDH ( Synchronous Digital Hierarchy, 同步数字体系)传输网络 中, 扩缩容的实现主要通过利用复用段环和交叉板实现。 而在 PTN设备中, 扩缩环过程中, 相关的网元软硬件的处理关系和逻辑更加复杂。 要进行较多 的数据和配置的修改, 各种配置信息之间还存在关联关系或依赖限制条件, 必须要按正确的步骤进行配置信息下发。 另外扩缩环时, 是在原来已经承载 了业务的链路上插入或去掉一个网元, 相应的链路物理上肯定会被断掉, 所 以必须要有备用链路才能保证业务的不中断, 即设备要支持保护功能。  In the traditional SDH (Synchronous Digital Hierarchy) transmission network, the implementation of the expansion and contraction is mainly realized by using the multiplex section ring and the cross board. In the PTN device, the processing relationship and logic of the related network element software and hardware are more complicated during the expansion and contraction process. To perform more data and configuration changes, there is a relationship between the various configuration information or restrictions. You must follow the correct steps to deliver the configuration information. In addition, when a ring is expanded or expanded, a network element is inserted or removed on the link that has already carried the service, and the corresponding link is physically disconnected. Therefore, a backup link must be provided to ensure uninterrupted service. That is, the device needs to support the protection function.
发明内容 本发明在上述的背景下, 为满足日益增长的容量扩展需求, 提出了一 种在保证不中断现有业务的条件下, 完成对环形网络扩缩环, 即增加或删除 一个或多个节点的方法和系统。 并且大家简化用户的操作流程, 提高扩缩环 的安全性和快捷性。 Summary of the invention In the above background, in order to meet the increasing capacity expansion requirement, an extension ring of a ring network, that is, adding or deleting one or more nodes, is proposed under the condition of ensuring that the existing service is not interrupted.

实施例一  Embodiment 1
本实施例提供一种在分组传送网中进行扩环的方法, 通过网管和节点设 备的配合处理流程, 把复杂的扩环功能操作简易化、 并提高扩环过程的正确 性和安全性, 为用户提供安全可靠的扩环功能。 下面结合具体实施例对本发 明作进一步的说明。 The embodiment provides a method for expanding a ring in a packet transmission network, which facilitates the operation of a complex expansion function and improves the correctness of the expansion process through a cooperation process between the network management system and the node device. Sex and security, providing users with a safe and reliable expansion function. The invention will now be further described in conjunction with specific embodiments.
环网组网的常见拓朴如图 4所示, PE1-P2-PE4-P3 ( PE: 表示用户接入节 点; P表示中间节点)这 4个网元组成一个环网结构, 为 PE1 -P3-PE4之间的 业务配置环网保护。 扩环的过程是在环网的 2个直连的网元之间增一个或多 个网元节点, 比如在 PE1和 P3之间增加网元 PP; 而缩环的过程正好相反, 比如把 PE1和 PE4之间的网元 P2去掉。  The common topology of the ring network is shown in Figure 4. PE1-P2-PE4-P3 (PE: indicates the user access node; P indicates the intermediate node). The four network elements form a ring network structure, which is PE1 - P3. - Configure the ring network protection between PEs. The process of expanding the ring is to add one or more network element nodes between two directly connected network elements of the ring network, for example, adding a network element PP between PE1 and P3; and the process of shrinking the ring is just the opposite, for example, PE1 The network element P2 between PE4 and PE4 is removed.
下面以在 PE1和 P3之间加入 PP网元节点进行扩环为例, 对本发明实施 步骤进行详细的说明, 如图 5所示, 可以包括下面步骤:  The following is a detailed description of the implementation steps of the present invention by adding a PP network element node between PE1 and P3. As shown in FIG. 5, the following steps may be included:
210: 网管对选中的网元(包括增加进来的网元 )进行锁定, 不允许其他 网管进行配置等操作。  210: The NMS locks the selected NEs (including the added NEs), and does not allow other NMSs to perform configuration operations.
网管必须检查节点设备和网管的数据是一致的, 并且配置信息都正确才 能允许进入扩环的处理流程。 进入流程后,  The NMS must check that the data of the node device and the NMS are consistent, and the configuration information is correct to allow the process to enter the extended ring. After entering the process,
220: 网管接收到用户的扩环指令;  220: The network management system receives the user's expansion command;
具体地, 网管界面提示用户选择需要扩环的链路和端口, 用户可以选择 Specifically, the network management interface prompts the user to select a link and a port that need to be expanded, and the user can select
PE1和 P3间直接相连的一个或多个端口。 One or more ports directly connected between PE1 and P3.
230: 网管对相关节点的配置信息分别进行处理;  230: The network management processes the configuration information of the related nodes separately.
根据用户选择的端口, 自动计算出所有与所述端口有关的受影响的业务 等配置信息, 并根据加入网元 PP的基础信息(包括 IP和 MAC (媒体接入控 制)信息等 ) , 完成对 PE1和 P3中配置信息的计算和修改。 并根据计算出的 配置信息为网元 PP创建必须的配置信息, 如隧道、 业务等。 所有数据都生 成后, 暂存这些配置信息。  According to the port selected by the user, all the configuration information about the affected service related to the port is automatically calculated, and the basic information (including the IP and MAC (Media Access Control) information, etc.) of the added network element PP is completed. Calculation and modification of configuration information in PE1 and P3. Based on the calculated configuration information, create configuration information, such as tunnels and services, for the NE. After all data is generated, these configuration information is temporarily stored.
240: 对所有影响的业务进行强制倒换;  240: Forced switching of all affected services;
对当前业务流程在扩环端口上的业务进行倒换, 使其切换倒换 PE1-P2-PE4 的方向去。 以保证在修改 PE1-P3 方向的配置时不造成业务中 断。 倒换成功后, 按特定的顺序下发配置给三个网元 PE1 , PP和 P3。  The service of the current service process is switched on the expansion port to switch the direction of PE1-P2-PE4. To ensure that the configuration in the PE1-P3 direction is modified without causing service interruption. After the switchover is successful, the configuration is delivered to the three network elements PE1, PP, and P3 in a specific order.
250: 如果所有网元都下发配置成功, 则扩环成功, 并把三个网元的配 置数据保存到网管数据库。 本发明实施例还提供一种信息处理方法, 如图 6所示, 可以包括下面步 骤: 250: If all the NEs are successfully configured, the expansion is successful, and the configuration data of the three NEs is saved to the NMS database. An embodiment of the present invention further provides an information processing method, as shown in FIG. 6, which may include the following steps:
S21、 节点设备接收到网管下发的配置信息后, 对该配置信息进行校 验;  S21. After receiving the configuration information delivered by the network management system, the node device performs the verification on the configuration information.
S22、 通过校验后, 根据所述配置信息按预定顺序进行配置。  S22. After passing the verification, the configuration is performed according to the configuration information in a predetermined order.
扩环时修改的配置信息很多, 需要根据命令不同调用相应的配置模块进 行数据处理。  There are a lot of configuration information modified when expanding the ring. You need to call the corresponding configuration module to process data according to different commands.
步骤 S21中, 对该配置信息进行校验包括:  In step S21, the verifying the configuration information includes:
判断网管下发的配置信息与本地存储的配置信息不一致情况下, 如判断 所述配置信息包括的数据正确, 且所述数据满足业务的关联关系和依赖条 件, 则视为所述配置信息通过校验。  If it is determined that the configuration information delivered by the network management system is inconsistent with the configuration information stored locally, if the data included in the configuration information is correct, and the data meets the association relationship and the dependency condition of the service, the configuration information is regarded as being passed through the school. Test.
即, 将网管下发的配置信息和节点设备当前本地的配置信息进行分析比 较, 对于没有变化的配置不做处理, 仅对有变化的配置信息进行增加、 删除 和修改等操作, 尽可能地减少对业务的影响。  That is, the configuration information sent by the network management system and the current local configuration information of the node device are analyzed and compared, and the configuration that has not changed is not processed, and only the changed configuration information is added, deleted, and modified, and the operation is reduced as much as possible. The impact on the business.
还必须对数据有效性和正确性的严格检查, 如果下发的配置信息中存在 错误, 则需要返回错误, 并提示明确的错误信息; 如果数据是正确的, 还需 要分析数据是否满足业务的关联关系和依赖条件, 比如配置伪线绑定隧道 时, 必须先配置好隧道; 如果这 2个条件有任何一个步骤出错, 则需要把前 面改动的配置还原为原来的配置。  You must also strictly check the validity and correctness of the data. If there is an error in the configuration information delivered, you need to return an error and prompt an explicit error message. If the data is correct, you need to analyze whether the data meets the service association. Relationships and dependencies, such as configuring a pseudowire binding tunnel, must first configure the tunnel; if any of these two conditions are faulty, you need to restore the previously changed configuration to the original configuration.
本实施例中, PE1、 P3和新加入的网元 PP的主控模块则根据具体场景和 各种业务内部逻辑关系, 调整配置的顺序, 然后按正确的顺序下发给线卡进 行处理。  In this embodiment, the main control modules of PE1, P3, and the newly added NEs are adjusted according to the specific scenarios and internal logic relationships of various services, and then sent to the line card for processing in the correct order.
配置的顺序是很关键的, 如果下发顺序不正确, 线卡的处理需要根据配 置顺序进行关联处理, 如果配置步骤存在错误, 很容易导致业务的中断, 所 以这里主控和线卡的配合至关重要。  The order of configuration is critical. If the order of delivery is incorrect, the processing of the line card needs to be processed according to the configuration order. If there is an error in the configuration step, it is easy to cause service interruption. Therefore, the master and line card are matched here. It is important.
线卡根据收到的配置信息, 进行处理并下发到驱动, 使配置信息生效, 如果下发失败, 需要把前面改动的配置还原为原来的配置; 如果成功, 配置 信息生效, 主控板存储该配置信息, 进行存库处理。 图 7为本发明实施例的网管扩环时下发配置的流程图, 网管需要对扩环 相关的网元进行配置的下发, 并保证配置下发的顺序, 以业务工作方向的扩 容为例说明: The line card is processed and sent to the driver according to the received configuration information. The configuration information takes effect. If the configuration fails, the configuration changed to the original configuration. If the configuration succeeds, the configuration information takes effect. This configuration information is used for repository processing. FIG. 7 is a flowchart of a configuration for transmitting a network management pipe in an embodiment of the present invention. The network management system needs to perform the configuration of the network element related to the expansion of the network, and the order of the configuration is as follows. :
410: 网管首先向 PE1和 P3下发强制倒换命令;  410: The NMS sends a mandatory switching command to PE1 and P3.
把业务流程强制切换到保护通道, 这样修改工作方向的配置信息时, 才 能不影响业务。  Forcibly switch the business process to the protection channel so that the configuration information of the working direction can be modified without affecting the service.
420: 网管先下发对 PE1网元的配置信息的修改;  420: The network management device first sends a modification to the configuration information of the PE1 network element.
在配置信息的下发顺序中, 需要考虑各类配置信息间的关联依赖关系, 比如端口、 ip 和 mac地址等基础配置信息必须先下发修改, 否则后面修改 vlan等上层配置时就可能会出错。  In the order in which the configuration information is sent, you need to consider the association dependencies of various types of configuration information. For example, the basic configuration information such as port, ip, and mac address must be sent and modified first. Otherwise, the upper layer configuration such as vlan may be modified later. .
并且在下发修改隧道的配置时, 主控需要完成修改隧道的下一跳的同时 完成对保护组下一跳的修改, 且必须保证隧道的下一跳和保护组的下一跳一 致。  When the configuration of the tunnel is modified, the master needs to complete the modification of the next hop of the tunnel and complete the modification of the next hop of the protection group. The next hop of the tunnel and the next hop of the protection group must be consistent.
430: 下发为网元 PP新建的业务配置信息, 为原来工作方向为 PE1-P3 的业务打通在路径 PE1-PP-P3上传输的通路, 即打通新的工作通道。  430: The service configuration information that is newly created by the network element PP is opened, and the service that is transmitted on the path PE1-PP-P3 is opened for the service whose original working direction is PE1-P3, that is, the new working channel is opened.
440: 下发网元 P3的配置信息, 下发的信息和处理处理流程与 420步类 似。  440: The configuration information of the network element P3 is sent, and the information and processing flow sent are similar to step 420.
