Description

网络接入设备的配置方法及装置 技术领域
本申请涉及但不限于通信技术领域。
背景技术
分发点模块(Distribution Point Unit，简称为：DPU)设备(即The node that resides at the DP in the Fiber To The Distribution Point architecture)属于网络综合接入设备模块中的一种，是面对最终用户的网络综合接入设备；该设备下接用户终端，上连服务商网络，由服务提供商提供多种网络服务。
DPU设备部署地点多样化，一般部署在小区，街道，路边等，部分设备采用用户反向供电方式，这类设备运行受限于用户上线数，用户下线会出现设备掉电离线，在这种情况下，使用相关技术中直接配置管理技术(即直接在设备配置界面上配置)存在一定的问题，当运营商开通用户业务时，设备并不在线，配置无法下发到设备执行，从而导致开通业务失败，影响设备运营维护。
业内一般方法是保证设备上电，或者派遣工程人员到现场进行配置，但是这些方法的有很多缺点：设备的部署受到电源限制，很多设备部署在非临近用户地方，不容易找到合适的电源；派遣工程人员现场开通业务，对于部署点繁多的接入设备，非常耗费时间和人力；用户业务变更，需要现场工程人员配置支持，响应慢。
为了解决上述问题，相关技术中提供了一种通信设备的数据离线配置方法，该方法是将设备配置信息转换为可人工修改编辑的数据库文件格式，然后将修改后的文件再逆转换为设备配置信息文件，导入设备的一种离线配置方法，但是该方案并不能解决设备不在线时，对设备进行管理的问题。
相关技术中还提供了一种离线数据的配置方法，在该方案中，系统分为前台设备和后台设备，通过直接在后台设备上内置命令解析模块等，进行直接命令配置，保证在前台设备未准备就绪情况下的后台设备配置，然而，该 技术在后台设备不在线的情况下，无法对设备进行管理。

本发明的实施方式
下文中将结合附图对本发明的实施方式进行详细说明。需要说明的是，在不冲突的情况下，本文中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸根据一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本发明实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
图1为本发明实施例提供的一种网络接入设备的配置方法的网络架构示意图，本发明实施例可以运行于图1所示的网络架构上，如图1所示，该网络 架构包括：网管服务器101、配置服务器102(也可以称为：网管服务器)、网络接入设备103以及用户设备104，其中，存储服务器可以设置在配置服务器102上。
如图1所示，网络接入设备103和配置服务器102的系统架构图，维护人员通过网管服务器101，例如为运营支撑系统(Operation Support System，简称为：OSS)服务器下发配置指令，开通用户业务；配置指令将传输到配置服务器102的北向接口，该配置服务器102例如为网络管理系统(Network Management System，简称为：NMS)，该配置服务器102内置永久配置存储管理代理(PMA)，配置指令由配置服务器102存储及解析后下发到网络综合接入设备DPU中，从而用户驻地设备(Customer Premises Equipment，简称为：CPE)设备正常上网，并享受服务商提供的网络服务。
本发明实施例的技术方案，其主要包括将网络集中接入设备配置数据信息保存在不中断电源的高可靠性网管设备的永久配置存储管理代理(Persistent Management Agent，简称为：PMA)中。
根据配置变更的频度特点，将设备配置文件分为三类配置文件形式，并利用配置订阅和发布机制，及时将最新配置下发到设备执行，该配置文件的传输使用安全文件传输协议(Secure File Transport Protocol，简称为：SFTP)。
本发明实施例中的网络接入设备的配置信息存储于高可靠性的服务器的PMA(即上述图1所述的存储服务器)中，PMA同时作为一个SFTP服务器端，监控用户配置的变更，同时发布配置变更信息。
本发明实施例中的网络接入设备的配置信息存储在三种配置文件中，该三种配置文件分别是预配置文件，基础配置文件和增量配置文件，通过对这三类配置文件的离线管理，形成本发明实施例的配置方法。
首先对三类配置文件进行描述：
(1)、预配置文件(即默认配置文件)，该配置文件中的配置一般作为出厂配置，例如，预置设备互联网协议(Internet Protocol，简称为：IP)地址，预置PMA地址等。预配置文件不需要在PMA上进行存储，仅保存在设备本地闪存(Flash EEPROM Memory，简称为：FLASH)中。
(2)、基础配置文件，该基础配置文件中存储着同类设备的通用配置，这部分配置改动的频率很小，存储于PMA上；更改基础配置文件的建议操作方式包括：
a)、直接手工修改基础配置模板，存放到PMA服务器上。
b)、通过网管界面，上传一台运行中网络接入设备DPU的配置，得到DPU运行配置文件后，手工修改作为基础配置文件，存放到对应PMA服务器上。
(3)、增量配置文件，对于频繁修改的配置信息规划到增量配置文件中，每个端口用户开通的数据，可通过北向接口设置，及网管平台设置；增量配置文件存储于PMA上，DPU本地保留镜像。增量配置文件使用通用描述语言进行描述，例如使用扩展标记语言(eXtensible Markup Language，简称为：XML)，该增量配置文件中，包含用户开通业务及取消业务的所有配置信息。
在本发明实施例中提供运行于上述网络架构的网络接入设备的配置方法，图2为本发明实施例提供的一种网络接入设备的配置方法的流程图，如图2所示，本实施例提供的网络接入设备的配置方法可以包括如下步骤，即步骤210～步骤230：
步骤210，在网络接入设备启动之后，网络接入设备向存储服务器发送用于订阅配置文件的请求；
步骤220，网络接入设备接收存储服务器响应该请求发布的配置文件信息，其中，存储服务器配置在配置服务器中，配置文件信息中包括基础配置文件的信息和增量配置文件的信息，基础配置文件用于记录网络接入设备的通用配置信息，增量配置文件用于记录用户变更业务的配置信息；
步骤230，网络接入设备根据配置文件信息，更新网络接入设备的配置。
本发明实施例提供的网络接入设备的配置方法，通过在网络接入设备启动之后，向配置服务器订阅配置文件，配置服务器中的存储服务器发布配置文件信息，从而网络接入设备根据该配置文件的信息更新配置；本实施例实现了及时更新离线配置。
通过上述实施例的技术方案，可以实现网络接入设备的离线配置及时同 步和更新；避免工程人员到每个站点对网络接入设备(即DPU设备)进行配置更新操作；配置服务器管理下属所有DPU设备的配置和状态信息，提供网络管理员或者运营维护人员友好的操作界面。
在上述实施例中，DPU设备启动之后，向PMA服务器(即配置服务器)订阅配置信息，PMA服务器发布配置信息，并推送到DPU设备侧；DPU设备根据推送信息，确认是否需要下载并更新配置。上述实施例中的基础配置文件和增量配置文件均存储于高可靠性的服务器设备中，通过配置发布和订阅方式，实现网络接入设备的配置及时同步和更新。
可选地，图3为本发明实施例提供的另一种网络接入设备的配置方法的流程图。在图2所示实施例的基础上，配置文件信息中还可以包括配置文件名和文件服务器信息，步骤230所述的网络接入设备根据配置文件信息，更新网络接入设备的配置的实现方式为，包括步骤231～步骤232：
步骤231，网络接入设备根据配置文件名检测该网络接入设备的配置是否有更新；
步骤232，网络接入设备在检测出配置有更新时，从文件服务器信息指示的文件服务器下载已更新的配置文件并更新该网络接入设备的配置。
可选地，在本发明实施例中，步骤231所述的网络接入设备根据配置文件名检测该网络接入设备的配置是否有更新，可以包括：若配置文件名与网络接入设备的本地存储器中配置文件的文件名一致时，网络接入设备检测出没有更新；若配置文件名与网络接入设备的本地存储器中配置文件的文件名不一致时，网络接入设备检测出有更新。
可选地，在本发明实施例中，步骤232所述的网络接入设备从文件服务器信息指示的文件服务器下载已更新的配置文件并更新该网络接入设备的配置的实现方式可以为：一方面，网络接入设备在配置文件名与本地存储器中配置文件的文件名中的更新时间信息不一致时，下载已更新的配置文件，并根据该已更新的配置文件更新配置，其中，更新时间信息用于表示配置文件已更新；另一方面，网络接入设备在配置文件名与本地存储器中配置文件的文件名中的更新时间信息不一致，下载已更新的配置文件，使用该已更新的配置文件覆盖本地存储器中的配置文件，并根据该已更新的配置文件更新 配置，同样，更新时间信息用于表示配置文件已更新，其中，配置文件中的时间戳不一致，也就是在线时间信息不一致，说明设备存在中间不在线过程，需要根据已更新的配置文件来更新配置，即在线时间信息用于表示在配置配置文件的过程中网络接入设备有不在线过程。
可选地，在网络接入设备启动之后、且在网络接入设备向配置服务器发送订阅配置文件的请求之前，本实施例提供的方法还可以包括：网络接入设备加载网络接入设备的本地存储器中的默认配置文件；网络接入设备执行默认配置文件，建立网络接入设备与存储服务器的通信。

可选地，如图4所示，本实施例提供的方法可以包括如下步骤，即步骤301～步骤313：
步骤301，加载预配置文件。在系统启动之后，执行该步骤。
步骤302，执行预配置文件获得DPU设备的IP地址。
步骤303，检测本地基础配置镜像是否存在。
若存在，则执行步骤304；若不存在，则执行步骤307。
步骤304，加载基础配置文件。

若存在，则执行步骤306；若不存在，则执行步骤307。
步骤306，加载增量配置文件。

当网络接入设备(即DPU设备)上电后，设备向配置服务器(即PMA服务器)发送协议报文，进行配置订阅。所有用户配置，都经过PMA服务器处理，PMA服务器对存储在服务器硬盘上的配置文件更新，并同时根据订阅设备列表进行配置发布流程。
步骤308，DPU设备下载已更新的基础配置文件和增量配置文件。
步骤309，检测文件名时间戳B是否更新。
若有更新，则执行步骤S310；若未更新，则不执行任何操作，随后转到步骤301。
步骤310，下载配置文件。
步骤311，检测文件名时间戳A是否更新。
若有更新，则执行步骤312；若未更新，则执行步骤313。
步骤S312，下载已更新的配置文件并更新配置。
步骤S313，下载已更新的配置文件并更新配置，并使用下载的已更新的配置文件覆盖本地文件，随后转到步骤301。
在实际应用中，用户配置DPU设备需要经过PMA服务器处理，PMA服务器将更新配置文件，如果DPU设备不在线，则需要更新配置文件A和B两个时间信息；如果DPU设备在线能正常配置，则只需要更新配置文件B时间信息；DPU设备对于PMA服务器发布的配置文件处理方法为，如果时间戳A与本地镜像不一致，表示需要同步配置文件，还需要重新配置DPU设备的端口配置；如果时间戳A一致，时间戳B不一致，表示只需要同步文件。
可选地，为了更容易检测配置信息的变化，配置文件文件名设计如下，这样DPU设备只要根据PMA服务器发布的配置文件名信息就可以进行已更新的配置文件的下载和更新判定了。例如，基础配置文件命名可以为：Basic_1502101200_1502121200-dpu.xml，其中包含两个时间戳信息，即时间戳A和时间戳B，时间戳A为：1502101200，意思为上一次探测到DPU设备不在线时间为2015年2月10日12点0分，时间戳B为：1502121200，意思为上一 次配置文件内容变化时间为2015年2月12日12点0分；时间戳A更新说明网元DPU设备中间存在不在线过程，网元DPU设备需要重新加载配置文件，时间戳B更新说明配置文件变化，网元DPU设备需要从SFTP服务器(SFTP Server)下载已更新的配置文件镜像。
可选地，在本发明实施例中，步骤210所述的网络接入设备向配置服务器发送用于订阅配置文件的请求的实现方式可以包括：网络接入设备周期性向该配置服务器发送该请求。
可选地，在本发明实施例中，网络接入设备周期性向该配置服务器发送该请求可以包括：网络接入设备周期性向该配置服务器发送用于订阅配置文件的请求；或者还可以包括：网络接入设备周期性查询文件服务器上的配置文件信息，其中，该文件服务器的信息为网络接入设备在存储服务器第一次发布配置文件信息时获得；在查询到的配置文件信息和存储服务器上一次发布的配置文件信息不一致时，重新向该配置服务器发送该请求。
本发明实施例提供的网络接入设备的配置方法，网络接入设备和配置服务器之间保持心跳，进行周期性的配置文件订阅和发布；该保持心跳不仅可以及时发现配置文件更新并从配置服务器上进行下载同步；该保持心跳包括但不限于网络接入设备和配置服务器保存周期性心跳，也可以是网络接入设备和文件服务器保存心跳，当发现上一次发布的文件变化时，再向配置服务器进行订阅，并根据存储服务器发布的信息及时发现配置文件更新并从配置服务器上进行下载同步。
在网络接入设备中内置一个SFTP客户端(SFTP Client)和SFTP服务器(SFTP Server)进行周期性交互，当发现上一次下载在网络接入设备的配置文件在SFTP服务器上已不存在时，说明配置文件有更新，网络接入设备需要重新订阅配置文件，网管配置服务器将发布新的配置文件和SFTP信息反馈给网络接入设备，网络接入设备进行下载更新。
网络接入设备检测基础配置和增量配置是否有更新，发现有基础配置更新，则在基础配置文件下载到本地后，覆盖本地基础配置镜像，下载增量配置并解析覆盖；当仅发现增量配置有更新，下载，解析增量配置，然后执行增量配置。
通过上述实施例，网络接入设备中包括预配置文件，基础配置文件和增量配置文件，网络接入设备和配置服务器的配置文件订阅和发布流程构成一种离线配置管理方法。
下面结合图5对本发明实施例提供的网络接入设备的配置方法进行详细描述。
如图5所示，为本发明实施例提供的网络接入设备的配置方法的交互流程图。本实施例提供的方法可以包括如下步骤，即步骤401～步骤404：
步骤401，网络接入设备(即DPU设备10)周期性向永久配置存储管理代理(PMA服务器20)发送用于订阅配置文件的订阅请求；
步骤402，PMA服务器20发布对应的配置文件信息，并推送给DPU设备10；
步骤403，DPU设备10获取PMA服务器20推送的配置文件信息和SFTP信息；
步骤404，DPU设备10向SFTP服务器30发送配置请求，该配置请求用于请求执行配置下载并更新。
在本实施例的一个可选地实现方式中，可以包括如下步骤，即步骤405～步骤407：
步骤405，网络接入设备(即DPU设备10)周期性查询SFTP服务器30上的配置文件，SFTP服务器30信息为DPU设备10在PMA服务器20第一次发布并推送配置文件信息时获得。
如果配置文件和PMA服务器20上一次发布的配置文件不一致，则重新向PMA服务器20发起订阅请求。
步骤406，PMA服务器20发布对应的配置文件信息，并推送给DPU设备10。
步骤407，DPU设备10根据推送的配置文件信息和SFTP信息，向SFTP服务器30发送配置请求，进行配置下载并更新。
与相关技术中的离线配置技术相比，本发明实施例提供的网络接入设备 的配置方法的有益效果为：通过采用发布订阅方式，提高配置的及时更新；因为配置更新都是文件形式，网管接入设备配置量普遍较大，根据配置变更频度设计三类配置文件，不需要每次都更新整个配置文件，减少每次需要变更的配置量；通过网管接入设备检测配置文件是否仍然存在，如果不存在才进行新的订阅，较少订阅/发布配置文件的协议交互，减轻配置服务器集中式管理负荷；将前一次的配置文件镜像保存在设备本地存储器中，如果配置未发生变更，不需要每次都进行配置下载过程，提升效率；配置更新自动化，开通用户业务更新配置不需要设备在线，降低运营维护成本和提高运维效率。
通过本发明实施方式提供的方法，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件。基于这样的理解，本发明实施例的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明实施例和可选实施方式提供的方法。

步骤520：存储服务器响应该请求并向网络接入设备发布配置文件信息，其中，存储服务器配置在配置服务器中，配置文件信息用于网络接入设备更新配置，配置文件信息中包括基础配置文件的信息和增量配置文件的信息，基础配置文件用于记录网络接入设备的通用配置信息，增量配置文件用于记录用户变更业务的配置信息。
