Description

业务节点主备切换方法和装置 技术领域  Service node active/standby switching method and device
本发明涉及通讯领域， 特别是涉及一种业务节点主备切换方法和装置。 背景技术  The present invention relates to the field of communications, and in particular, to a service node active/standby switching method and apparatus. Background technique
业务节点（Service Node, SN )也可以称为用户业务控制设备， 例如宽 带远端接入服务器（ Broadband Remote Access Server, BRAS )或业务路由 器（ Service Router, SR )等， 随着通过 SN接入宽带的用户数量越来越多、 以及宽带用户对宽带高可靠性的要求越来越高， 运营商对用户备份接入的 要求也越来越高。 因此， SN间广泛使用了用户信息备份技术。  A service node (SN) may also be referred to as a user service control device, such as a Broadband Remote Access Server (BRAS) or a Service Router (SR), etc., with access to the broadband through the SN. The number of users is increasing, and the requirements for broadband high reliability of broadband users are getting higher and higher, and operators are increasingly demanding backup access for users. Therefore, user information backup technology is widely used among SNs.
在现有技术中， 用户备份技术是指双机热备份或多机热备份， 接入节 点（Access Node, AN )接入多个上行 SN, 主用 SN的接入端口和备用 SN 的备份端口——对应， 主备 SN 釆用虚拟路由冗余协议 ( Virtual Router Redundancy Protocol , VRRP ) 和双向转发检测 ( Bidirectional Forwarding Detection, BFD )技术来切换状态。 主用 SN把接入用户信息同步到备用 SN,备用 SN在收到主用 SN传递的用户信息时，立刻将该用户信息以用户 表的方式下发到接口模块。 当主用 SN的接入端口接入用户的链路故障时， 备用 SN切换成主用 SN, 用户流量同时发生切换， 切换后用户的上下行流 量都通过备用 SN转发， 备用 SN基于已备份的用户信息对用户业务流进行 控制和管理。  In the prior art, the user backup technology refers to dual-system hot backup or multi-machine hot backup, and the access node (AN) accesses multiple uplink SNs, the primary SN access port and the backup SN backup port. —— Correspondingly, the active and standby SNs use the Virtual Router Redundancy Protocol (VRRP) and Bidirectional Forwarding Detection (BFD) technologies to switch states. The primary SN synchronizes the access user information to the standby SN. When receiving the user information transmitted by the primary SN, the standby SN immediately sends the user information to the interface module in the form of a user table. When the access port of the primary SN access port is faulty, the standby SN is switched to the primary SN, and the user traffic is switched at the same time. After the handover, the uplink and downlink traffic of the user is forwarded through the standby SN, and the standby SN is based on the backed up user. Information controls and manages user traffic.
目前，现有技术中是将主备切换协议和 SN下行到 AN的端口或链路状 态进行关联， 并通过链路连通性探测的方式， 当探测到 SN下行 AN的链路 或者 SN端口发生故障时， 进行主备 SN的切换。  Currently, in the prior art, the active/standby switchover protocol is associated with the port or link state of the SN downlink to the AN, and the link connectivity detection mode is used to detect that the link of the SN downlink AN or the SN port is faulty. At the same time, the master/slave SN is switched.
在现有技术中， 链路探测技术不能够探测到主用 SN设备的内部异常， 例如， 在主用 SN的中央处理器、 内存的利用率过高时， 也会造成用户转发 异常， 但由于探测不到主用 SN设备的内部异常， 链路状态仍然显示正常， 不会进行 SN主备切换， 从而导致用户转发或者用户接入的异常。 发明内容 In the prior art, the link detection technology cannot detect the internal abnormality of the primary SN device. For example, when the central processor of the primary SN and the memory usage are too high, the user may also forward the abnormality. However, since the internal abnormality of the primary SN device is not detected, the link status is still normal and the SN is not performed. The master/slave switchover causes the user to forward or the user accesses an exception. Summary of the invention

为了解决现有技术中探测不到主用 SN设备的内部异常而导致的用户 转发或者用户接入异常的问题， 本发明提供了一种业务节点主备切换方法 和装置， 以下结合附图以及实施例， 对本发明实施例的技术方案进行进一 步详细说明。 应当理解， 此处所描述的具体实施例仅仅用以解释本发明， 并不限定本发明。 In order to solve the problem that the internal abnormality of the primary SN device is not detected in the prior art The present invention provides a service node active/standby switching method and apparatus. The technical solution of the embodiment of the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
方法实施例  Method embodiment
根据本发明的实施例， 提供了一种业务节点主备切换方法， 图 1 是本 发明实施例的业务节点主备切换方法的流程图， 如图 1 所示， 根据本发明 实施例的业务节点主备切换方法包括：  According to an embodiment of the present invention, a service node active/standby handover method is provided. FIG. 1 is a flowchart of a service node active/standby handover method according to an embodiment of the present invention. As shown in FIG. 1, a service node according to an embodiment of the present invention is provided. The active/standby switching methods include:
步骤 101 , 通过主备状态切换协议建立业务节点的主备关系， 将主备状 态与主用业务节点的***状态相关联， 并配置***状态的异常阔值； 其中， 主备状态切换协议可以包括以下之一： 虚拟路由冗余协议、 多机架链路聚 合协议。也就是说， 在步骤 101中， 主备 SN可以通过诸如 VRRP这种主备 状态切换协议建立主备关系，但主备状态切换协议并不限制于 VRRP,也可 以是多机架链路聚合 ( MC-LAG )协议。  Step 101: Establish an active/standby relationship of the service node by using the active/standby state switching protocol, and associate the active/standby state with the system state of the active service node, and configure an abnormal threshold of the system state. The active/standby state switching protocol may include One of the following: Virtual Routing Redundancy Protocol, Multi-Rack Link Aggregation Protocol. That is, in step 101, the active and standby SNs can establish an active/standby relationship through an active/standby state switching protocol such as VRRP, but the active/standby state switching protocol is not limited to VRRP, and may also be multi-chassis link aggregation ( MC-LAG) protocol.
此外， ***状态可以包括以下至少之一： 硬件运行状态、 软件运行状 态、 设备***告警。 也就是说， 对于主备状态和***状态的关联， 既可以 包括和设备级的***运行状态， 例如 CPU、 或内存使用情况关联， 也可以 包括和设备某一硬件的运行状态相关联， 例如， 可以和交换网板运行状态 关联， 还可以和设备某一功能模块的运行状态关联。 此外， 在主备切换协 议和***状态相关联时， 可以选择同时关联多个不同的***状态， 这些状 态之间的逻辑关系可以是 "与" 或者 "或" 的关系。  In addition, the system status can include at least one of the following: hardware operating status, software operating status, device system alarm. That is to say, the association between the active and standby states and the system state may be associated with the system operating state of the device level, such as CPU or memory usage, or may be associated with the running state of a certain hardware of the device, for example, It can be associated with the running status of the switching stencil and can also be associated with the running status of a functional module of the device. In addition, when the active/standby switchover protocol is associated with the system state, you can choose to associate multiple different system states at the same time. The logical relationship between these states can be "or" or "or".
综上所述， 在步骤 101中， 主备 SN可以将设备的***运行状态、 重要 告警和主备状态切换协议关联， 并配置相应的临界阀值（即， 上述异常阔 值）。  In summary, in step 101, the active and standby SNs can associate the system running status, important alarms, and active/standby status switching protocols of the device, and configure corresponding threshold thresholds (ie, the above abnormal thresholds).
步骤 102, 根据主用业务节点的当前***状态、 异常阔值、 以及主备关 系， 通过主备状态切换协议进行业务节点主备切换。 Step 102: According to the current system state of the active service node, an abnormal threshold, and a primary and secondary switch The active/standby switchover of service nodes is performed through the active/standby state switching protocol.
也就是说， 当设备***状态严重异常达到临界阀值或者有相关严重告 警产生时， SN联动主备状态切换协议对 SN进行主备切换； 当原主用 SN 设备***运行状态恢复正常或者严重告警消失时， SN联动主备状态切换协 议回切主备状态。 在实际应用中， 主备状态与***状态的关联， 可以选择 切换和回切使用不同的条件去关联主备 SN状态切换。 例如， 切换条件 A 导致主备切换（即， 主用 SN切换到备用 SN ), 切换条件 B导致回切（即， 备用 SN切换到主用 SN )。  That is, when the critical state of the device system reaches a critical threshold or a serious alarm occurs, the SN-linked active/standby state switching protocol performs the active/standby switchover of the SN; when the original active SN device system is restored to normal or the critical alarm disappears. The SN and the active/standby state switching protocol switch back to the active/standby state. In actual applications, the association between the active and standby states and the system state can be selected to switch and switch back to use different conditions to associate the active and standby SN state switches. For example, handover condition A results in an active/standby switchover (ie, the primary SN switches to the standby SN), and handover condition B results in a failback (ie, the standby SN switches to the primary SN).
具体可以进行处理：  Specifically can be processed:
确定达到第一切换条件， 根据业务节点的主备关系通过主备状态切换 协议进行业务节点主备切换， 其中， 第一切换条件为： 确定主用业务节点 的当前***状态出现告警或主用业务节点的当前***状态的异常值大于或 等于异常阔值；  Determining that the first switching condition is reached, and performing the active/standby switchover of the service node by using the active/standby state switching protocol according to the active/standby relationship of the service node, where the first handover condition is: determining that the current system state of the active service node has an alarm or a primary service The abnormal value of the current system state of the node is greater than or equal to the abnormal threshold;
确定达到第二切换条件， 根据业务节点的主备关系通过主备状态切换 协议进行业务节点主备回切， 其中， 第二切换条件为： 确定主用业务节点 的当前***状态的告警消失或主用业务节点的当前***状态的异常值小于 异常阔值。  The second switching condition is determined, and the active/standby switchback protocol is used to perform the active/standby switchback of the service node according to the active/standby relationship of the service node, where the second handover condition is: determining that the current system state alarm of the active service node disappears or the primary The outlier value of the current system state with the service node is less than the abnormal threshold.
优选地， 在实际应用中， 可以以修改业务节点优先级的方式通过主备 状态切换协议进行业务节点主备切换。  Preferably, in an actual application, the active/standby switchover of the service node may be performed by using the active/standby state switching protocol in a manner of modifying the priority of the service node.
此外， 在主备状态切换协议与设备***告警 （包括网管告警）相关联 的情况下， 可以由网管设备控制业务节点主备切换。 也就是说， 当主备状 态协议和某些严重相关的设备***告警关联时，可以由网管设备通过 SNMP 通知 SN主备状态切换。  In addition, when the active/standby state switching protocol is associated with the device system alarm (including the network management alarm), the network management device can control the active/standby switchover of the service node. That is to say, when the active/standby protocol is associated with some seriously related device system alarms, the network management device can notify the SN of the active/standby state switching through SNMP.
图 2是本发明实施例的业务节点主备切换方法的详细处理流程图， 如 图 2所示， 根据本发明实施例的技术方案包括如下处理： 步骤 201 , SN通过主备状态切换协议建立主备关系， 其中， 主备 SN 可以通过 VRRP建立主备关系； 2 is a detailed processing flowchart of a method for switching between active and standby of a service node according to an embodiment of the present invention. As shown in FIG. 2, the technical solution according to an embodiment of the present invention includes the following processing: Step 201: The SN establishes an active/standby relationship through the active/standby state switching protocol, where the active and standby SNs can establish an active/standby relationship through VRRP.
步骤 202, SN将设备***运行状态、或者设备某软 /硬件模块运行状态， 或者重要相关告警和主备状态关联， 并配置临界阀值；  Step 202: The SN associates the operating state of the device system, or the running status of a certain software/hardware module of the device, or an important related alarm with the active/standby state, and configures a critical threshold;
步骤 203 ,当设备***运行状态严重异常达到临界阀值或者有相关严重 告警产生时， SN联动主备状态切换协议对 SN进行主备切换；  Step 203: When the operating state of the device system is severely abnormal and reaches a critical threshold or a related serious alarm is generated, the SN performs an active/standby switchover between the SN and the active/standby state switching protocol.
步骤 204,当原主用 SN设备***运行状态恢复正常或者严重告警消失， SN联动主备状态切换协议回切主备状态。  Step 204: When the running status of the original active SN device system is normal or the serious alarm disappears, the SN linkage active/standby state switching protocol switches back to the active/standby state.
从上述处理可以看出， 本发明实施例将双机备份的切换机制和设备系 统状态相关联， 当发现设备状态严重异常或者某个严重告警产生时， 触发 设备的主备切换协议开始主备切换， 可以规避虽然由于***严重异常造成 无法切换的问题。  It can be seen from the foregoing that, in the embodiment of the present invention, the switching mechanism of the dual-system backup is associated with the system state of the device. When the device status is abnormally abnormal or a serious alarm is generated, the active/standby switching protocol of the triggering device starts the active/standby switchover. , can avoid the problem of being unable to switch due to serious abnormalities in the system.

That is to say, the establishing module 30 can establish an active/standby relationship through an active/standby state switching protocol such as VRRP, but the active/standby state switching protocol is not limited to VRRP, and may also be a multi-chassis link aggregation (MC-LAG) protocol. .
此外， ***状态可以包括以下至少之一： 硬件运行状态、 软件运行状 态、 设备***告警。 也就是说， 对于主备状态和***状态的关联， 既可以 包括和设备级的***运行状态， 例如 CPU、 或内存使用情况关联， 也可以 包括和设备某一硬件的运行状态相关联， 例如， 可以和交换网板运行状态 关联， 还可以和设备某一功能模块的运行状态关联。 此外， 在主备切换协 议和***状态相关联时， 可以选择同时关联多个不同的***状态， 这些状 态之间的逻辑关系可以是 "与" 或者 "或" 的关系。  In addition, the system status can include at least one of the following: hardware operating status, software operating status, device system alarm. That is to say, the association between the active and standby states and the system state may be associated with the system operating state of the device level, such as CPU or memory usage, or may be associated with the running state of a certain hardware of the device, for example, It can be associated with the running status of the switching stencil and can also be associated with the running status of a functional module of the device.

In practical applications, the active and standby states and system states For the association, the switching module 32 can select the switching and failback to use different conditions to associate the active and standby SN state switching. For example, the switching condition A causes the switching module 32 to perform the active/standby switching (ie, the primary SN switches to the standby SN), and the switching condition B causes the switching module 32 to perform the failback (ie, the standby SN switches to the primary SN).
切换模块 32具体可以进行处理：  The switching module 32 can be specifically processed:
切换模块 32确定达到第一切换条件， 根据业务节点的主备关系通过主 备状态切换协议进行业务节点主备切换， 其中， 第一切换条件为： 确定主 用业务节点的当前***状态出现告警或主用业务节点的当前***状态的异 常值大于或等于异常阔值；  The switching module 32 determines that the first switching condition is reached, and performs the active/standby switchover of the service node by using the active/standby state switching protocol according to the active/standby relationship of the service node, where the first switching condition is: determining that the current system state of the active service node is alarmed or The abnormal value of the current system state of the active service node is greater than or equal to the abnormal threshold;
