- CORBA is a standard object-oriented application architecture specification developed by the OMG Object Management Organization. It consists of an Object Request Broker (ORB), an object service, a public facility, a domain interface, and an application interface. At its core is the Object Request Broker ORB, which provides a mechanism by which objects can transparently make requests and receive responses.
- ORB Object Request Broker
- the disadvantage of the CORBA interface is that it is too large and complicated. The debugging of the docking is difficult and the scalability is poor. When the interface changes, both sides of the docking must be recompiled, and the development cost is high.
- the FTP interface refers to the information generated by the network management timer.
- the integrated network management system uses the FTP protocol. Get these files and parse them in the specified format.

Description
一种实现北向接口的方法及装置
技术领域
本发明涉及通信系统的网络管理领域, 尤其涉及一种实现北向接口的方 法及装置。
背景技术
随着电信产业的高速发展, 电信网络的规模不断扩大, 设备种类和组网 方式也越来越复杂和多样化。 目前, 各个运营商的设备往往是由多家不同厂 商的设备共同组成, 每个厂商都有自己设备的网元管理系统 (Element Management System, EMS ) , 但是这些网元管理系统之间无法提供统一的接 口信息模型和数据指标, 对网络的集中管理带来了困难。
针对上述问题, 为了实现对全网的统一管理, 局方希望能够在目前分散 的网管系统的基础上建立综合的网络管理系统( Network Management System, NMS ) , 这就要求各个厂商在自己特有的网元管理系统中, 提供面向综合网 络管理系统的统一接口, 即北向接口。 北向接口可以屏蔽各个网元管理系统 和设备之间的差异性, 实现对不同厂商、 不同网络类型的一体化管理, 降低 网络管理的复杂度。
目前常见的北向接口协议有 CORBA (公共对象请求代理体系结构) 、 FTP (文件传输协议) 、 XML ( SOAP/Web Service ) 、 SNMP (简单网络管理 协议)和 TL1 (交易语言 1 ) 。 其中:
CORBA是由 OMG对象管理组织制订的一种标准的面向对象的应用程序 体系规范。 由对象请求代理(ORB ) 、 对象服务、 公共设施、 域接口和应用 接口组成。 其核心部分是对象请求代理 ORB, ORB提供了一种机制, 通过这 种机制,对象可以透明的发出请求和接收响应。 CORBA接口的缺点是过于庞 大和复杂, 对接调试困难并且扩展性差, 当接口发生变化时, 对接双方都要 重新编译, 开发成本高。
FTP接口是指网管定时将需要的信息生成文件, 综合网管通过 FTP协议
获取这些文件并按照指定的格式进行解析。 FTP接口方式适合于上层网管向 下层网管获取大数据量的情况, 不适于实时性要求较高的情况, 也不适用于 上层网管对 EMS进行操作的情况。
XML ( SOAP/Web Service )是一种轻量的、 简单的、 基于 XML的协议, 它被设计成在 WEB上交换结构化的信息。 XML接口的缺点是冗余数据大, 传输效率较低, 消息中使用的 XML每次都必须做解析, 解析效率相对较低, 而且权限控制比较麻烦。
SNMP是由 IETF定义的一套基于 UDP的网络管理协议, 简单易用, 是 事实上的网络管理工业标准。 SNMP基于 Manager/Agent模型进行管理,釆用 管理信息基础 (Management Information Base, MIB )和相关的命令集进行信 息交互, SNMP Tra 是 SNMP协议中的消息主动上报机制。 SNMP接口的缺 点在于综合网管 NMS不能通过 EMS直接进行命令行接口 (Command Line Interface, CLI )方式的命令下发业务操作。 目前传统的命令行接口 CLI已经 成为大多数设备厂商普遍支持的接口, 因此釆用命令行接口的方式对网元进 行配置是目前网管系统釆用的主流技术手段。
TL1是一种基于 TCP连接的标准的电信管理协议, TL1对接简单, 调试 方便, 扩展性好, 易于理解和使用。 为了支持综合网络管理系统进行业务下 发, 需要在网元管理系统中提供 TL1北向接口, TL1北向接口一方面用于接 收 TL1命令请求, 另一方面用于完成 TL1命令到具体 CLI命令的适配和转换 过程, 实现与具体网元的交互, 运营商釆用 TL1协议进行业务下发在电信领 域成为首选, 从实际的使用情况来看, TL1 目前已经成为使用最为广泛的北 向接口协议。
现有 TL1北向接口开发的特点是:针对每个 TL1命令,开发者(应用侧) 都要关注 TL1协议本身的处理问题, 包括 TL1协议格式的解析、 TL1命令到 具体设备命令的映射, 消息响应格式的包装和返回等。 因此这种开发模式带 来了如下问题:
( 1 )开发门槛较高, 开发者的关注点太多, 开发者不仅仅要关注业务逻 辑本身, 还要关注 TL1协议信息的解析, TL1命令的权限、 安全控制和日志 等其他问题, 因此, 这种开发模式不利于关注点的分离, 开发的效率低, 维
护起来也比较困难。
( 2 )传统的 TL1北向接口缺乏对 TL1消息的集中控制。 由于开发者本 身的差异性, 其消息返回的风格迥异, 消息结构的一致性较差。
( 3 )可扩展性不足, 当网元版本升级或者新增加一种新类型的网元时, 网管的北向接口程序必须进行同步升级。
( 4 ) TL1消息处理的自动化程度不高。 现有的开发模式大多使用不同的 业务处理类处理不同的 TL1命令,没有建立 TL1命令到具体 CLI命令的自动 映射和组装机制, 动态适应性较差。 发明内容

综上所述,本实施方式对于 TL1命令,可以根据网元类型和版本的不同, 动态生成 CLI命令下发给到网元, 对于 TL1命令也能够动态加载不同的业务 逻辑处理类处理, 因而弥补了当网元版本升级时, EMS北向接口也需要重新 进行开发的不足, 使得北向接口的开发和维护成本大大降低, 并且, 本实施 方式对 TL1命令釆用统一的消息处理和命令下发机制,以及釆用统一的安全、 曰志和事务管理,提高了开发效率;对于新增的 TL1命令,无需重新修改 EMS 网管的代码, 只需修改知识库的配置文件, 即可完成 EMS的调整, 可以达到 快速地响应客户需求的目的。 附图概述
图 1为 TL1北向接口的应用场景图;
图 2为本实施方式的实现北向接口的装置的功能框图;
图 3为本实施方式的实现北向接口的方法的处理流程图。 本发明的较佳实施方式
本实施方式的北向接口的实现方法及装置能够动态自适应地实现 TL1北 向接口的功能, 针对上层网管的请求, 结合本地知识库和网元类型进行动态 推理决策, 智能地生成与网元交互的 CLI命令, 并提供统一的消息处理和返 回机制。 同时可以灵活地注入具体的业务逻辑处理类, 对特殊的 TL1请求进 行处理。 TL1 北向接口的消息处理过程对业务逻辑处理类是透明的, 便于集 中精力处理业务逻辑, 实现了关注点的有效分离。 本实施方式实现的 TL1北
向接口具有良好的动态自适应能力, 可以显著地提高北向接口的开发效率, 快速响应客户的需求变化。
下面结合附图和具体实施实例对本发明进一步描述。
图 1为 TL1北向接口在 EMS中的位置和应用场景, 本实施方式的 TL1 北向接口部署在 EMS的服务器端, 接收上层的 NMS的 TL1北向请求, 并完 成 TL1请求到 CLI命令的转换和适配, 实现对网元的配置。
图 2为本实施方式的实现北向接口的装置, 包括: 鉴权实体、 语法分析 实体、 请求适配实体、 命令映射组装实体、 业务处理实体以及命令下发实体, 其中:
鉴权实体负责对所接收的所有 TL1请求进行统一的权限控制, 拒绝非法 请求。
语法分析实体负责消息 "^文的语法检测, 过滤异常消息。
请求适配实体负责请求的频繁度分析, 防止恶意攻击行为, 并根据 TL1 知识库动态决策是否生成 CLI命令 /命令组, 或者将请求分派到业务处理实体 进行处理。
业务处理实体负责对于有特殊处理需求的命令进行处理。
命令下发实体负责将 CLI命令 /命令组下发到具体的网元以及读取网元的 响应信息。
为实现本实施方式的方法需要预先建立权限控制文件和知识库。
建立权限控制文件, 对上级网管中的不同的用户进行分权分域管理。 权 限控制文件可以配置多个不同的用户, 不同用户可以拥有不同的操作权限。 权限控制文件包括用户、 用户能够执行的操作以及操作设备所属的域。 权限 控制文件不仅可以配置允许用户执行的 TL1命令条目, 也可以配置允许用户 操作的 MOC实例的范围。
以下面的 XML的权限控制文件为例予以具体说明。
<?xml version="1.0" encoding="UTF-8"?>
<user name="admin" alloperation="true" alldomain="tme"/>
<user name="test">
<operations>
<operation>
<operation tl 1 name="IP-BND-ACLLN -PORT">
</operation>
</operations>
<domain>
<ipranges startip="10.40.111.0" endip="10.40.111.102" />
<ipgrp ip=" 10.40.111.106"/>
</domain>
</user>
在上面的权限控制文件中, 建立了 admin和 test两个用户。
alloperation="tme"表示 admin用户可以下发所有的北向接口支持的 TL1 命令。
alldomain="true"表示 admin用户可以对所有的 MOC实例进行操作。
test用户则只能执行 "IP-BND-ACLLNK-PORT"命令, 同时该用户只能在 domain约束的 MOC实例范围中下发 TL1命令。 MOC实例的范围可以是单独 的一个网元, 也可以是一组网元。
建立半结构化或者结构化知识库, TL1北向接口可以根据接收到的 NMS 的北向 TL1请求, 通过知识库进行综合性的推理决策, 动态生成具体的 CLI 命令下发到设备。
知识库中存储有以下内容:
( 1 ) TL1命令到网元 CLI命令的转换相关信息。
( 2 ) 网元版本与具体 CLI命令的映射关系。
( 3 ) TLl命令到具体业务逻辑类的映射关系。
具体地, 知识库的建立有两种方式, 一种是使用数据库的方式建立结构 化知识库, 另一种是使用配置文件的方式建立半结构化的知识库。
下面以 TL1命令' ΊΡ-TLl-ACLLINK-PORT"为例,说明以配置文件的方式 建立知识库:
<?xml version:" 1.0" encoding="UTF-8"?>
<Command TLl -command="IP-TLl -ACLLINK-PORT"
commandFormat="IP-B D-ACLL K-PORT:: (DIP=device-ip/DNAME=device-name): CT AG::IFNAME=port name,ACLID=acl number,DIRECTION=direction; "
useEMS="false" maxfreg=10 businessClassName=" ">
<TLl-param>
<param index:" 1" name="IFNAME" value="" type="0" range=""/>
<param index="2" name="ACLID" value="" type=" 1 " range="200-299"/> <param index="3" name="DIRECTION" value="" type=" 1 " range="0-l"/>
</TLl-param>
<CLI neVersion="V4.08.30-V4.08.32" MOC="CTN90,CTN95">
<cliCommand index:" 1 " value="interface $ {paraml } "/>
<cliCommand index="2" value="ip access-group ${param2} $ {param3 } "/>
</CLI>
<CLI neVersion="V4.08.23" MOC=" Switch— 89">
<cliCommand index:" 1 " value="int $ {paraml } "/>
<cliCommand index="2" value="ip access-group ${param2} $ {param3 } "/>
</CLI>
<Value-Map>
<map name="DIRECTION" nmsValue=" 1 " emsMapValue="in" />
<map name="DIRECTION" nmsValue="2" emsMapValue="out" />
</Value-Map>
</Command>
如图 3所述本实施方式将 TL1命令转换为 CLI命令的方法, 包括:
301 : EMS接收到 NMS的 TL1命令请求后, 从该请求中解析得到 NMS 上当前的用户名称、 EMS下网元的设备类型、设备 IP地址、 TL1命令名称以 及输入的命令参数和参数值的哈希映射表(name ValueHashTable ) ;
302: 北向接口中的鉴权实体根据用户名称、 命令名称, 解析权限控制文 件对用户和 TL1命令进行鉴权;
303: 如果鉴权通过, 则执行步骤 304; 否则, 执行步骤 313;
304:鉴权实体调用语法分析实体进行 TL1命令的语法分析,语法分析实 体根据知识库中该 TL1命令的命令格式,对接收到的 TL1命令进行语法分析;
305: 语法分析实体判断语法分析是否通过, 通过则执行步骤 306进行请 求频繁度分析; 否则, 执行步骤 313;
306:语法分析实体调用请求适配实体,请求适配实体对 TL1命令的请求 频繁度进行分析, 以防止非授权用户恶意攻击带来的安全问题;
每条命令的 TL1请求频度阔值存储在知识库中, 如上述配置文件描述的 maxfreg=10表示每分钟超过 10次的 TL1命令请求, EMS拒绝进行进一步操 作。
307:请求适配实体判断 TL1命令的请求频繁度分析是否通过,通过则执 行步骤 308; 否则, 执行步骤 313;
308:请求适配实体根据知识库中配置的该 TL1命令的处理方式标识,判 断 TL1命令的具体处理方式;
309: 如果是釆用透传处理, 则执行步骤 310; 否则, 执行步骤 312;
知识库中的 "useEMS"为 TL1 命令' ΊΡ-TLl-ACLLINK-PORT"的处理方式 标识, useEMS="false"表示釆用透传处理, useEMS="true"表示从 businessClassName中读取业务逻辑处理类的路径,釆用业务逻辑处理类处理。
310:请求适配实体将 TL1命令委托给命令映射和组装实体,命令映射和 组装实体将 TL1命令组装为 CLI命令;
命令组装的详细步骤如下:
步骤 A1: 根据网元信息 (如 IP地址)读取网元的 MOC和版本信息, 根 据 MOC和版本信息从知识库中的 TL1命令与 CLI配置集的映射关系信息中 查找 TL1命令对应的 CLI配置集;
CLI配置集即为上述配置文件中 cliCommand对应的 value值集。 TL1命 令与 CLI配置集的映射关系信息中 TL1命令至少对应一个以 MOC信息和版 本信息标识的 CLI配置集。
步骤 A2: 针对 TL1命令对应的 CLI配置集, 自上而下扫描 cliCommand 的 ¥&11½值( CLI命令),如果当前扫描到的 CLI命令中含有配置参数( aram ), 则执行步骤 A3; 否则,将当前扫描到的 cliCommand的 value值加入待下发的 CLI命令组中;
步骤 A3:解析出步骤 A2中的配置参数的参数索引 (即 cliCommand中的 param后面的数字, 如 paraml中的 1 ) , CLI参数索引和 TL1命令参数的映 射关系存储在知识库的 TLl-param节点中, 参数索引对应的 TL1命令参数的 参数值可以通过 nameValueHashTable表直接查找到, nameValueHashTable表 中保存有命令参数与参数值的映射关系信息, 将得到的 TL1命令参数的参数 值替换 cliCommand的$ ^ &11^}部分, 并将替换后的内容加入待下发的 CLI 命令组中;
注意: 在知识库中对于一些 TL1 命令还包含参数值映射关系信息 ( <value-map> ) , 在 nameValueHashTable表中查找到参数名称的值后, 如果 在 <value-map>标签之间能找到该参数名称, 则需要釆用该参数的值 ( nmsValue的映射值 )对应的 emsMap Value替换 CLI命令模板的 ${paramx} 部分。
当完成针对一网元版本和 M0C下的全部 cliCommand扫描后, 即完成了 CLI命令组的构造。
311 : 命令下发实体将 CLI命令组下发到对应的网元, 下发成功后, 进行 操作日志的记录。
312: 业务处理实体读取知识库中 businessClassName中的业务逻辑处理 类的路径, 执行具体的业务逻辑处理类进行处理;
313: 构建 TL1响应消息, 返回给上层网管系统 NMS。
本实施方式中还可以对 TL1知识库进行扩充, 实现对知识库的管理。 TL1知识库存储在网管系统的服务器端。 TL1知识库的扩充可以使用客 户端的图形用户界面进行输入, 这使得网管可以在运行中动态扩充知识库, 因此, 本实施方式对 NMS的动态请求具有较强的动态适应性, 包括 TL1命 令名称、 命令语法格式、 TL1参数名称、 TL1参数类型和 TL1参数范围等。 CLI命令、 CLI参数与 TL1参数的映射关系和 NMS参数与 EMS参数的映射 关系。
基于数据库的知识库的组织方式与基于配置文件的知识库的组织方式是 ——对应的, 基于数据库的知识库具体的组织方式如下, 可以分为以下四个 表。
表一: TL1命令基本属性表
表二: TLl参数表
IP-B D-ACLL K Switch_89 V4.08.23 2 ip
-PORT access-group
${param2}
${param3}
表四: NMS与 EMS参数值映射关系表
下面以 IP-BND-ACLLNK-PORT命令, 基于数据库方式的知识库为例说 明将 TL1命令转换为 CLI命令的方法, 包括:
步骤 B1 : 解析得到命令名称 IP-BND-ACLLNK-PORT, 根据 DIP (设备 IP )得到 MOC 类型以及具体的网元版本, 各个 TL1 参数的值分别为: IFNAME=gei_2/l , ACLID=200 , DIRECTION=0, 将参数名称和值的映射关 系存储到哈希表( nameValueHashTable ) 中;
步骤 B2 : 根据 MOC 类型以及网元版本, 扫描表三中命令 IP-BND-ACLLNK-PORT 对应的 CLI 命令模板 interface ${paraml} , 根据 interface ${paraml}对应的索引 1查找表二, 得到索引 1对应 IFNAME (端口 名称),从 nameValueHashTable中查找 IFNAME的值 gei_2/l替换 ${param 1 } , 得到 CLI命令 interface gei— 2/1加入 CLI命令组;
类似地, 查找到 ACLID的值 200替换掉 ${param2}, 查找到 DIRECTION 的值 0, 通过读取表 4 ( NMS与 EMS参数值映射关系表)转换为 in, 替换掉
$ {param3 } , 生成第二条命令 ip access-group 200 in力口入到 CLI命令组; 步骤 B3: 调用命令下发实体将 CLI命令组的命令下发到具体的网元。 通过步骤 B1和 B2得到具体的命令组如下:
interface gei— 2/1 ;
ip access-group 200 in。
该 CLI命令的功能是将 ACL绑定物理接口 gei— 2/1入方向。
从以上步骤可以看出, 本实施方式根据上层网管 EMS的 TL1请求可以 基于知识库推理决策自动生成 CLI命令组, 同时也可以将请求分派给具体的 业务逻辑类处理, 其统一的消息解析和安全管理机制实现了关注点的有效分 离, 可以大大提高北向接口的开发效率, 同时也具有较好的扩展性和通用性。
显然, 本领域的技术人员应该明白, 上述的本发明的各实体、 各步骤可 以用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 或 者将它们分别制作成各个集成电路实体, 或者将它们的多个实体或者步骤制 作成单个集成电路实体来实现。 这样, 本发明不限制于任何特定的硬件和软 件结合。
以上所述仅为本发明的实施例而已, 并不用于限制本发明, 对于本领域 的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则 之内, 所做的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围 之内。
工业实用性

类处理, 因而弥补了当网元版本升级时, EMS北向接口也需要重新进行开发 的不足,使得北向接口的开发和维护成本大大降低,并且,本实施方式对 TL1 命令釆用统一的消息处理和命令下发机制, 以及釆用统一的安全、 日志和事 务管理, 提高了开发效率; 对于新增的 TL1命令, 无需重新修改 EMS网管 的代码, 只需修改知识库的配置文件, 即可完成 EMS的调整, 可以达到快速 地响应客户需求的目的。
